Many diseases classified as complex and of multifactorial origin, such as cancer, diabetes, and hypertension respond better
to treatments consisting of several drugs. But multiple dosing of medicines and the increasing risk of drug interactions and side
effects lead to the development of patient non-compliance to composite therapy. Polypharmacology emerged through research
in multifunctional compounds and has helped resolve these problems. Such new chemical entities (linked to more effectively
fighting disease) must interact with various receptors, triggering multiple biological effects, that when united fight the disease
more effectively, these are the Multi-target drugs in drug discovery (MTDD). Selective modulators of certain targets or closely
related groups of targets, in fact, act via modulation of multiple proteins with diverse functions. Multi-target drugs against selected
multiple targets improve therapeutic efficacy, safety, and resistance profiles by collective regulation of the primary therapeutic
target, together with related compensatory elements and resistance activities. New multifunctional compounds have
emerged as a modern trend in drug research that are reinforced by studies based on big data, where global view investigations
of multiple causes and effects are a growing trend. This issue, Recent Medicinal Chemistry Studies for Multitarget Agents-Part II,
brings manuscripts from different countries reporting recent research studies in multi-target drugs.
Pain is an unpleasant sensation that have complex and various causative etiology. Modern drug discovery focuses on identifying
potential molecules that target multiple pathways with safer profile compared to those with a single target. Current treatment
of pain and inflammation with the available therapeutics has a number of major side effects. Pain is one of the major clinical
problems that needs functional therapeutics which act on multiple targets and with low toxicity. Curcumin, a naturally occurring
polyphenolic compound from Curcuma longa, has been used for years in Ayurvedic, Chinese, and in many other systems
of traditional medicine. Pre-clinical data published thus far, demonstrated that curcumin possesses multi-target biological
functions, suggesting its potential use to cure different diseases. However, there is no or little systematic review on its potential
use in pain and inflammation with underlying mechanisms for such activities. Accordingly, the aim of the review of Dr Mubarak
and co-workers, Curcumin and its Multi-target Function Against Pain and Inflammation: An Update of Pre-clinical Data,
was to update the pre-clinical data of curcumin and its multiple targeting pathways for analgesic and anti-inflammatory action,
and to further propose a molecular mechanism. Literature study was conducted using different known databases including
Pubmed, Sci-finder, Google scholar, and Science Direct. Available pre-clinical data suggest the ameliorating effect of curcumin
in pain and inflammation is rendered through the modulation of a of pain pathways including inhibition of a number of proinflammatory
mediators, inhibition of oxidative stress and Cox-2, down-regulation of Ca2+/calmodulin-depend protein kinase
II (CaMKIIα) and calcium channels like transient receptor potential (TRP), modulation of metabotropic glutamate receptor-2
(mGlu2), modulation of monoamine system, inhibition of JAK2/STAT3 signaling pathway, remodeling of extracellular matrix
proteins, inhibition of apoptosis, inhibition of JNK/MAPK and ERK/CREB signaling pathway, and activation of opioid system.
Taken all together, it is evident that curcumin is one of the promising safe natural polyphenolic molecules that target multiple
molecular pathways in pain, and can be beneficial in the treatment and management of pain and inflammation.
Parkinson’s disease is one of the most common adult-onset, a chronic disorder involving neurodegeneration, progressively
leading to deprivation of dopaminergic neurons in substantia nigra, causing a subsequent reduction of dopamine levels in the
striatum resulting in tremor, myotonia, and dyskinesia. Genetics and environmental factors are believed to be responsible for
the onset of Parkinson’s disease. The exact pathogenesis of Parkinson's disease is quite complicated and the present anti-
Parkinson's disease treatments appear to be clinically insufficient. Comprehensive researches have demonstrated the use of
natural products such as ginseng, curcumin, ashwagandha, baicalein, etc. for the symptomatic treatment of this disease. The
neuroprotective effects exhibited by these natural products are mainly due to their ability to increase dopamine levels in the
striatum, manage oxidative stress, mitochondrial dysfunction, glutathione levels, clear the aggregation of α-synuclein, induce
the autophagy and decrease the pro-inflammatory cytokines and lipid peroxidation. The paper entitled Herbal Resources to Combat a Progressive & Degenerative Nervous System Disorder- Parkinson’s Disease, of Dr Shen et al, reviewed various natural
product studies conducted by the scientists to establish the role of natural products (both metabolite extracts as well as
pure metabolites) as adjunctive neuroprotective agents.
Alzheimer’s disease is a common and most chronic neurological disorder (NDs) associated with cognitive dysfunction.
Pathologically, Alzheimer’s disease (AD) is characterized by the presence of β-amyloid (Aβ) plaques, hyper-phosphorylated
tau proteins, and neurofibrillary tangles, however, persistence oxidative-nitrative stress, endoplasmic reticulum stress, mitochondrial
dysfunction, inflammatory cytokines, pro-apoptotic proteins along with altered neurotransmitters level are common
etiological attributes in its pathogenesis. Rivastigmine, memantine, galantamine, and donepezil are FDA approved drugs for
symptomatic management of AD, whereas tacrine has been withdrawn because of hepatotoxic profile. These approved drugs
only exert symptomatic relief and exhibit poor patient compliance. In the current scenario, the number of published evidence
shows the neuroprotective potential of naturally occurring bioactive molecules via their antioxidant, anti-inflammatory, antiapoptotic
and neurotransmitter modulatory properties. Despite their potent therapeutic implications, concerns have arisen in
context to their efficacy and probable clinical outcome. Thus, to overcome these glitches, many heterocyclic and cyclic hydrocarbon
compounds inspired by natural sources have been synthesized and showed improved therapeutic activity. Computational
studies (molecular docking) have been used to predict the binding affinity of these natural bioactive as well as synthetic
compounds derived from natural sources for the acetylcholine esterase, α/β secretase Nuclear Factor kappa-light-chainenhancer
of activated B cells(NF-kB), Nuclear factor erythroid 2-related factor 2(Nrf2) and other neurological targets. The
review of Dr Iqubal et al, Current Quest in Natural Bioactive Compounds for Alzheimer’s Disease: Multi-Targeted-Designed-
Ligand Based Approach with Preclinical and Clinical Based Evidence, discussed the molecular etiology of AD, focused on the
pharmacotherapeutics of natural products, chemical and pharmacological aspects and multi-targeted designed ligands
(MTDLs) of synthetic and semisynthetic molecules derived from the natural sources along with some important on-going clinical
Lack of adequate sleep is a major source of many harmful diseases related to heart, brain, psychological changes, high
blood pressure, diabetes, weight gain etc. The 40 to 50 % of the world’s population is suffering from poor or inadequate sleep.
Insomnia is a sleep disorder in which individual complaint of difficulties in starting/continuing sleep at least four weeks regularly.
It is estimated that 70% of the heart diseases are generated during insomnia sleep disorder. The main objective of this
study to determine the all work conducted on insomnia detection and to make a database. We used two procedures including
network visualization techniques on two databases including PubMed and Web of Science to complete this study. Dr Khan and
co-workers found 169 and 36 previous publications of insomnia detection in the PubMed and the Web of Science data-bases,
respectively. They analyzed 10 datasets, 2 databases, 21 genes, and 23 publications with 30105 subjects of insomnia detection.
The work, Progress in Detection of Insomnia Sleep Disorder: A Comprehensive Review, has revealed the future way and gap
so far directed on insomnia detection and has also tried to provide objectives for the future work to be proficient in a scientific
and significant manner.
Artificial Intelligence revolutionizes the drug development process that can quickly identify potential biologically active
compounds from millions of candidate within a short period. The review of Dr Nayarisseri and co-workers, Artificial Intelligence,
Big data and Machine Learning approaches in Precision Medicine & Drug Discovery, is an overview based on some
applications of Machine Learning based tools such as GOLD, Deep PVP, LIB SVM, etc. and the algorithms involved such as
support vector machine (SVM), random forest (RF), decision trees and Artificial Neural Networks (ANN), etc in the various
stages of drug designing and development. These techniques can be employed in SNP discoveries, drug repurposing, ligandbased
drug design (LBDD), Ligand-based Virtual Screening (LBVS) and Structure-based Virtual Screening (SBVS), Lead
identification, quantitative structure-activity relationship (QSAR) modeling, and ADMET analysis. It is demonstrated that
SVM exhibited better performance in indicating that the classification model will have great applications on human intestinal
absorption (HIA) predictions. Successful cases have been reported which demonstrate the efficiency of SVM and RF model in
identifying JFD00950 as a novel compound targeting against a colon cancer cell line, DLD-1 by inhibition of FEN1 cytotoxic
and cleavage activity. Furthermore, a QSAR model was also used to predict flavonoid inhibitory effects on AR activity as a
potent treatment for diabetes mellitus (DM), using ANN. Hence, in the era of big data, ML approaches evolved as a powerful
and efficient way to deal with the huge amounts of generated data from modern drug discovery to model small-molecule drugs,
Gene Biomarkers, and identifying the novel drug targets for various diseases.
We, the Guest-Editors, would like to express our gratitude to the many authors who contributed to this special issue, reporting
investigations in various aspects of RECENT MEDICINAL CHEMISTRY STUDIES FOR MULTITARGET AGENTSPART
The basic principle of action of a drug is based on model lock and key, where is desirable the highest possible affinity for a
target avoiding no side effects. For many years it was desirable‘one drug for one target for one disease’, however the
researchers observed that complex diseases are best addressed when treated with drugs multi-targets. However, in the recent
years the researches try find polypharmacology- drugs that act on multiple rather than single targets against complex diseases,
such as oncology, psychiatry and antiinfectives. Examples are: the fluoroquinone that inhibits two of the multiple penicillinbinding
proteins to induce cell death; anti-psychotic drugs exhibit activities in serotonin and dopamine receptors; the protein
kinase inhibitors, including sunitini (Sutent) and imatini (Gleevec) against cancer. In the searches, new drugs against a specific
target of one disease have been found to be active against another target of a different disease and/or reduce the resistance. All
additional activities of these drugs should be explored in repositioning them for new therapeutic applications. This special issue
was dedicated to multi-target chemicals (drugs, organic compounds, nanoparticles), including (but limited to) those with
dual (or multiple) mechanisms of action [1-10].
Our manuscript entitled In silico study examining new phenylpropanoids targets with antidepressant activity, conducted a
brief review of new important targets for antidepressant activity, to select potentially active phenylpropanoids, using Molegro
Virtual Docker and Ossis Data Warris, and thus, to verify which substance is more promising for antidepressant activity.
Curcumin, a major active principle of Curcuma longa. There are more than 1700 citations in the Medline reflecting various
biological effects of curcumin. Most of these biological activities are associated to the antioxidant, anti-inflammatory and antitumor
activity of the molecule. Several reports suggest various targets of natural curcumin that includes growth factors, growth
factor receptor, cytokines, enzymes and gene regulators of apoptosis. This review focuses on the improved curcumin derivatives
that targets the cancer and inflammation. The detailed analysis of structure activity relationship (SAR) and common synthesis
of curcumin-based derivatives are discussed in review of Dr Veena et al, Design of New Improved Curcumin Derivatives
to Multi-targets of Cancer and Inflammation. Utilising the predictions of in silico coupled with validation reports of in
vitro and in vivo studies have concluded many targets for curcumin. Among them, cancer related inflammation genes regulating
curcumin-based molecules are very promising target to overcome hurdle in the multimodality therapy of cancer. Physcion
and physcion 8-O-β-D-glucopyranoside (PG) are bioactive natural anthraquinones which exert anti-inflammatory and anticancer
properties with minimum or no adverse effects, this is the study of Dr Shah et al, entitled Physcion and Physcion 8-O-β-
D-glucopyranoside: Natural Anthraquinones with Potential Anti-cancer Activities.
Plant-derived compounds such as gallic acid and tannic acid are effective potentiators of various antibiotics including novobiocin,
chlorobiocin, coumermycin, fusidic acid, and rifampicin, resulting in a 4-fold increase in the potencies of these antibiotics.
Several lines of research, as discussed in the review Antibiotic potentiation of natural products: A promising target to
fight pathogenic bacteria, of Drs Mahomoodally & Sadeer. For this reason, the search for more efficient combinations should
be an ongoing process with the aim to extend the life of the ones that we have and maybe preserve the life for the ones that is
yet to come.
The study of Dr Tarannum et al entitled To Explore the Potential Targets and Current Structure-based Design Strategies
Utilizing co-crystallized Ligand to Combat HCV explored the various targets of HCV involved in the mechanism(s) of the
disease initiation and progression and to focus on the mode of binding of ligands, which are co-crystallized at the active cavity
of different HCV targets.
Dr Pirolla and co-workers discussed therapeutic targets involved in Alzheimer’s disease (AD) as well as the available drugs
and their synthetic routes. Bioactive com-pounds under development are also exploited to illustrate some recent research advances
on the medicinal chemistry of AD, including structure-activity relationships for some targets. The importance of multitarget
approaches, including some examples from our research projects, guides new perspectives in the search of more effective
drug candidates. Their review, Alzheimer's Disease: Related Targets, Synthesis of Available Drugs, Bioactive Compounds
Under Development, and Promising Results Obtained from Multi-target Approaches, comprises the period between 2001 and early 2020. The neuroprotective effects exhibited by natural products are mainly due to their ability to increase dopamine levels
in the striatum, manage oxidative stress, mitochondrial dysfunction, glutathione levels, clear the aggregation of α-
synuclein, induce the autophagy and decrease the pro-inflammatory cytokines and lipid peroxidation.
We, the Guest-Editors, would like to express our gratitude to the many authors who contributed to this special issue, reporting

Although the recent wide adoption of minimal invasive procedures for major oncological pelvic surgery and benign prostatic
hyperplasia (BPH) has provided improved functional and oncological outcomes, post-op sexual dysfunction rates remain
high. Can the postoperative use of phosphodiesterase type 5 inhibitors (PDE5i) offer remedy of erectile function after oncologic
pelvic surgery and do we have evidence for newer PDE5i categories? What is the impact of ablative surgery for BPH to sexual
dysfunction and what treatment choices urologists have in their armamentarium? Moreover, at a time where endourology is
flourishing is there a still place for phytotherapy and herbal agents for the management of kidney stones? Do the pros of neoadjuvant
chemotherapy (NAC) for muscle-invasive bladder cancer (MIBC) outweight the cons and furthermore are there new
effective and safe categories of chemotherapeutic drugs currently available for chemotherapy resistant patients? The above
questions have been thoroughly discussed in the current issue.
Lombardo et al.  have presented a detailed systematic review of the available literature regarding the efficacy of the already
established but also of newer PDE5i on the management of post-pelvic surgery erectile dysfunction (ED). PDE5i have
revolutionized the field of ED management by providing a handful of appealing characteristics including high efficacy rates,
excellent safety profile, good adherence to treatment and ease of use. Thus, despite the low, according to the authors, efficacy
of the four different PDE5is (sildenafil, tadalafil, vardenafil and avanafil) on post-pelvic surgery ED, these drugs still represent
the first-line treatment option (1). Nevertheless, the present systematic review concluded that although some patients may benefit
from the aforementioned PDE5is none of them can be clearly recommended as monotherapy for penile rehabilitation after
pelvic surgery. Moreover, the authors highlight that despite the encouraging preclinical and clinical evidence regarding the
efficacy of oro-dispersible (ODT) PDE5i formulations and new types of PDE5i, such as udenafil, lodenafil and mirodenafil,
the effect of these formulations in post-pelvic surgery erectile function has not been evaluated yet. Thus, there is a necessity for
future well-designed randomized clinical trials (RCTs) in order to clarify the role of these new compounds and ODT formulations
in the management algorithm of post-pelvic surgery ED.
Although to a much smaller degree compared to pelvic oncologic surgery, ED occurs even after surgical treatment of Benign
Prostatic Hyperplasia (BPH). In this scope, a narrative review by Mykoniatis et al.  assessed the prevalence, potential
pathophysiologic pathways and the proposed management of sexual dysfunction following ablative surgical techniques for
BPH. The techniques reviewed included photoselective vaporization of the prostate (PVP), transurethral needle ablation (TUNA),
transurethral microwave therapy (TUMT), convective water vapor energy ablation (REZUM®) and Aquablation®. Regarding
ED pathophysiologic mechanisms, it seems that PVP, TUNA, TUMT and REZUM, by being minimally invasive techniques,
avoid the direct cavernosal nerve damage intraoperatively due to posterolateral capsular perforation which may happen
during TURP procedure. However, the indirect thermal injury of cavernosal nerves and/or bladder neck nerves and also the
partial disruption of ejaculatory ducts represent potential ED and ejaculatory dysfunction (EjD) mechanisms after these surgical
techniques. On the contrary, Aquablation® by using physiological saline for tissue ablation and real-time penetration depth
control could potentially have a beneficial effect on postoperative erectile function. After reviewing the available data authors
reported that PVP, TUMT and TUNA have no impact or a mildly negative impact on erectile function and comparable or lower
rates of postoperative EjD, compared to TURP. Moreover, REZUM and Aquablation® techniques led to either no change or
even to amelioration of EF postoperatively (2). As potential preventive methods for the rare case of sexual dysfunction after
BPH surgery authors suggest the avoidance of intraoperative manipulation of crucial structures regarding ejaculatory (bladder
neck or ejaculatory ducts) and erectile (neurovascular bundles) functions. In cases of new or worsening ED or EjD postoperatively
then the already recommended treatment options are proposed. In other words, oral PDE5i as first line treatment, followed
by intracavernosal injection of alprostadil in cases of failure and penile prosthesis implantation as a permanent solution
for refractory to conservative treatment ED. Regarding EjD the proposed treatment options include medical therapy with aagonists
(pseudoephedrine), surgical reconstruction of the bladder neck, sperm retrieval from the urine, electroejaculation,
prostatic massage, penile vibratory stimulation and surgical sperm retrieval (2).
In another interesting review article available in the current CDT issue Emiliani et al.  performed a comprehensive review
of publications evaluating the efficacy of various phytotherapeutic and herbal agents for the prevention of kidney stones.
Despite the high number of commercially available phytotherapeutic agents for kidney stone, only a small number of relevant
clinical studies have been published with the majority of which including small number of participants and no active comparator
arm. According to the available data analyzed in this review Phyllanthus niruri and theobromine are currently the most
studied and most promising options for lithiasis prevention without having serious side effects (3). Specifically, Phyllanthus
niruri is accompanied by the most robust scientific evidence compared to other phytotherapies and is reported to interfere with
calcium oxalate crystallization and also reduce hyperuricosuria and hyperoxaluria. Moreover, it seems to play another benefi-cial role in lithiasis by positively affecting the success rates of shock wave lithotripsy through reduction of crystallization. Regarding
uric acid stones management studies evaluating the efficacy of theobromine have shown encouraging results as the use
of this supplement led to reduction of uric acid crystallization. Nevertheless, authors highlight the need for future RCTs in order
to furtherly evaluate the effect of these agents in the management of kidney stones (3). In an era where the majority of research
targets to stone treatment rather than stone prevention, the present review by reporting the potential key role of phytotherapies
in the latter may be of special interest both for endo-urologists and patients suffering from recurrent kidney stone
The last article published in the current issue by Calo et al.  is a systematic literature review evaluating the efficacy and
safety of the already established in the clinical practice but also of novel neoadjuvant therapeutic regimens for MIBC. Prospective
and retrospective studies published in the last 15 years were included. Platinum-based regimens remain the gold standard
of neo-adjuvant chemotherapy (NAC) with its main representatives being the combinations of methotrexate-vinblastineadriamycin-
cisplatin (MVAC), gemcitabine-cisplatin (GC), cisplatin-methotrexate-vinblastine (CMV) and cisplatinmethotrexate.
According to the available metanalytic data reported in the present review MVAC offers an improvement in the
absolute disease-free survival rate by 9% while CMV treatment results in a 16% reduction in mortality and also offers a 6%
improvement in the 10-year overall survival. Moreover, NAC regimens including gemcitabine showed comparable oncological
outcomes with MVAC. Interestingly, several studies showed no negative effect of NAC on perioperative morbidity and hospitalization
time (4). The new kids on the block for neoadjuvant treatment of MIBC, which are not cisplatin-eligible, are immunotherapeutic
agents targeting the PDL-1 pathways showing promising efficacy and safety results. The authors underline that
the establishment of biomarkers able to predict NAC response is a research field of high priority as it will enable clinicians to
select MIBC patients who will benefit the most while at the same time avoid delaying cystectomy for patients unlikely to respond.
Urologists are required to manage a wide spectrum of conditions ranging from the typical male patient with uncomplicated
lower urinary tract symptoms (LUTS) to advanced malignancies of the urinary tract that require extirpative, debilitating surgery
and multidisciplinary team management. Medical and surgical therapy are used either sequentially or complimentary to one
another for a variety of urological diseases. Advanced and challenging surgery is necessary in cases where medical therapy fails
while on the other hand medical therapy is used to alleviate complications and amend shortcomings of surgical interventions.
Recently, unprecedented evolutions in drug development as well as in surgical devices and techniques have created dilemmas
as to the optimal management of a variety of urological diseases. This special issue of CDT aims to investigate those interactions
between drugs and surgery in the treatment of the most common urological conditions; lower urinary tract symptoms and
When it comes to LUTS, medical therapy has historically been considered as the cornerstone of treatment, with ablockers
being the choice for first-line therapy either in combination with 5-ARIs or more commonly as sole treatment. Considering
that LUTS’s complex pathophysiology is not always related to the enlarged prostate, urologist have come to realize
that patients seeking treatment for LUTS are to a different extend bothered by storage and/or voiding symptoms, rendering
their therapeutic approach challenging. Since the “one-size-fits-all” rule does not apply to the pharmacological management
of LUTS, given the wide heterogeneity in the etiology and phenotype of patients with LUTS it appears inevitable that in
clinical practice, most of the patients will be advised to opt for combination therapy of an a-blocker with 5-a-reductase inhibitors
(5-ARIs) or antimuscarinics. Furthermore, assuming that BPH will progress for the majority of patients, combination
therapy with a-blockers and 5ARIs is a reasonable choice in an effort to lessen the risks of retention and prostate surgery
by decreasing prostate size.
On the other hand and while the limits of pharmacotherapy for BPH are still not very clear, patients do not stay for long on
BPH medications, especially on combination therapies, and this has a negative effect on the rates of hospitalization and BPH
surgery. Interestingly, a recent survey has shown that although most men were satisfied with their current medical therapy for
BPH, the majority (61%) were willing to participate in an alpha-blocker discontinuation trial. In addition to low adherence to
BPH medication, longstanding issues of their long-term efficacy, safety and negative impact on libido, ejaculation and quality
of life on sexually active patients further complicate their use.
The recent advent of innovative minimally invasive surgical techniques has further fueled the debate as to whether medical
treatment should remain the first line therapy for patients with LUTS/BPH and if so for which patients. Minimally invasive
surgical therapies (MISTs) including Prostatic Urethral Lift (PUL), transurethral water vapor therapy (Rezūm), iTIND and
Aquablation, have started gaining ground over conventional surgical modalities, namely TURP. MISTs confer several inherent
advantages, mainly preservation of sexual and ejaculatory function and avoidance of long-term use of drugs targeting patients
who opt for a quick, safe, reasonably durable, and less invasive procedure that will improve LUTS with minimal morbidity and
negligible side effects.
It could be argued that MITSs represent an equally good choice as medical therapy as first line treatments of BPH-related
LUTS sparing the drug-related side effects of orthostatic hypotension, asthenia and sexual dysfunction. Although no direct
studies exist comparing medical therapy to MISTs, Symeonidis and Sountoulides in the current issue offer a narrative review of
the available literature and provide an indirect comparative assessment of drugs versus MISTs for obstructive LUTS. Interestingly
improvements in symptoms and QoL favored MISTs over medical therapy, with the majority of drugs failing to demonstrate
a clear superiority . Despite these encouraging results, MISTs long-term durability is unknown given the relatively
short follow up time (maximum 5 years) of relevant studies. There is no doubt that further clinical studies are required for obtaining
solid evidence before definite conclusions are made about the place of MISTs in clinical practice and even more so as
first line treatment of BPH-related LUTS.
There is a handful of urological conditions where medical therapy is used to alleviate surgical outcomes or manage postoperative
side effects or complications. This holds true for persistent LUTS post-radical prostatectomy since bladder dysfunction
affects more than a third of the patients undergoing prostate cancer surgery. Although post-radical prostatectomy overactive
bladder (post-RP OAB) has a non-negligible incidence ranging from 15.2-37.8% with a negative effect on patient’s quality
of life, few studies have been conducted in order to evaluate response of post-RP OAB to pharmacotherapy.
Sakalis and Gkotsi in the present issue have presented an excellent and detailed overview of the available evidence on the
challenging management of post-RP OAB. Given the lack of relevant studies, current practice in post-RP OAB is mostly driven
by the outcomes of medical treatment of the general population with OAB symptoms. A stepwise management algorithm is
proposed starting with lifestyle modifications, behavioral therapy and pelvic floor muscle exercises which can result in up 50%
improvement in symptoms. There is evidence that post-RP OAB may respond well to intravesical Botox injection provided that
the patient is aware of the increased risk for the need of intermittent self-catheterization .
Although there are no studies on the efficacy of oral medications on the specific subgroup of patients with post-RP OAB
symptoms, anticholinergics and PDE-5 inhibitors are used in this scenario. Also no studies in the post-RP OAB setting have
examined the role of mirabegron, even though its efficacy in the general population with OAB appeared to be comparable to
that of anticholinergics . Duloxetine, a serotonin-noradrenaline reuptake inhibitor effective for SUI post RP, is known to
suppress bladder activity in animal studies however no studies have examined its efficacy in storage LUTS post-RP. The few
patients with refractory post-RP OAB should seek more invasive and complicated surgical procedures, namely urinary diversion
or augmentation cystoplasty.
This issue of CDT also deals with the management of patients with OAB refractory to bladder training and pharmacotherapy.
Despite the availability of different classes of anticholinergics and recently b3-agonists, patient adherence to medical treatment
of OAB remains low. According to a recent real world study on OAB patients on oral medications patient adherence was
low after 1 year of treatment with adherence being better for mirabegron than for anticholinergics. The cause of this low adherence
to therapy can be attributed to a number of reasons including patient’s unreasonable expectations from treatment, low
compliance due to side effects and reduced efficacy of drugs over time.
Several minimally invasive surgical procedures are available for patients with drug-resistant OAB. These therapies include
intravesical botulinum toxin type A, posterior tibial nerve stimulation, and sacral neuromodulation without any clear superiority
of one over another. The treatment algorithm for refractory OAB is dependent on several factors, including age, comorbidity,
patient preference, surgical expertise, and financial concerns. However intravesical Botox injections is usually the first choice
in cases of failure of medical therapy as the procedure is more familiar to the average urologist and requires less expertise and
Therefore, as Botox injections for refractory to oral medications OAB are increasingly gaining ground in every day urological
practice, Apostolidis et al. in the current issue of CDT have presented a very interesting and updated overview of the current
indications, precautions, outcomes and reasons for failure of intravesical Botox injections .
According to Apostolidis et al. preoperative patient assessment is key for the identification of the best candidates for Botox
as well as for appropriate patient consultation. Patients scheduled for Botox injections should be made aware of the risk of urinary
tract infections, incomplete bladder emptying or even urinary retention and hence will need to be prepared and trained for
the possibility of the need of, even temporary, intermittent self-catheterization.
Although the definition of Botox failure is not clear Apostolidis et al. have proposed measures to avoid Botox failure by
increasing the dose or shortening of injection intervals, particularly in neurogenic patients, switching to a different toxin or adding-
on anticholinergics or b-3 agonists. In case of persistent non response, treatment with percutaneous tibial nerve stimulation
or sacral neuromodulation are the next steps in the treatment algorithm . Research in the field should focus on identification
of pathogenetic mechanisms of failure, while clinical questions to be answered include the effect of previous anticholinergic
treatment on Botox efficacy as well as whether repeated treatments result in a progressive decline or shorter duration in Botox
The last article published in the current issue discusses the interactions between medical and surgical therapy in advanced
renal cancer. Cytoreductive nephrectomy is no longer the standard of care for patients with mRCC and intermediate-poor prognosis
following the results of two major RCTs, namely the CARMENA and SURTIME trials. Modern era targeted therapy with
TKIs, mTOR inhibitors and recently, immune checkpoint inhibitors should be the first option for the management of patients
with mRCC with cytoreductive surgery reserved for cases with either local symptoms from the tumor or following adequate
response to systematic treatment. Greco et al. discuss the evolution of medical therapies for mRCC from the era of interleukin-
2 and IFN-a to targeted therapies and towards immunotherapy . There is evidence that treatment with a combination of immunotherapeutic
agents, ipilimumab and nivolumab, is optimal to sunitinib for intermediate and poor risk patients. In this scenario,
the role of cytoreductive nephrectomy may be expected to change again. The authors also provide insights into the current
treatment algorithm for mRCC relevant to the optimal role, indications and sequencing of cytoreductive nephrectomy with
medical therapy .
A systematic analysis published just recently  shows that the prevalence of inflammatory bowel diseases (IBD) increased
considerably from 1990 to 2017 in many regions of the world. Moreover, the number of IBD cases worldwide has reached
nearly 7 million. Along come millions of dollars spent on anti-IBD drug development, as well as patient care. Altogether, IBD
has become a major social and economic burden for healthcare systems globally.
Coping with the matter needs better diagnosis and treatment, which require primarily better understanding of the disease.
This special issue discusses diagnostic and therapeutic potential of a wide range of molecules and approaches, from in vitro
engineered stem cells to nutritional support, which may visualize IBD or affect its pathogenesis at the earliest stages possible.
The issue starts with a review of the role of free fatty acid receptors in IBD and colitis-associated colorectal cancer . Next,
Binienda et al.  focus on the immune and epithelial stem cells, in view of both, their diagnostic and therapeutic potential.
Tarasiuk and Eibl  examine the possible value of probiotics, prebiotics and symbiotics as well as nutritional support in treatment
of IBD. Then, Stavely et al.  study bilateral relationships between the enteric nervous system and inflammation, including
the effects and mechanisms of inflammation-induced enteric neuronal loss and plasticity. Additionally, they explore the role
of enteric neurons in preventing antigenic/pathogenic insult and immunomodulation. Zatorski and Nakov  explain the principles
and methodology in fecal microbiota transplantation used as a treatment of IBD and verify its efficacy. In the paper of
Wang et al. , the concept of exosomes as a cell-free therapeutic approach is given full focus. The issue concludes with the
paper by Makaro et al. , who discuss the current state of knowledge regarding genetic differences between sporadic and colitis-
associated colorectal cancer and analyze the data from studies regarding the correlations between colitis-associated colorectal
cancer and the presence of Single Nucleotide Polymorphisms.
As of today, IBD is as seen a chronic and relapsing disease and it may still take several decades to cope with successfully.
However, articles presented in this Special Issue give hope to patients that finding early detection options and an efficient cure
In 1994, The American Journal of Pathology published a key article reporting that hypoxic retina produces vascular endothelial
growth factor (VEGF), sug- gesting a role for VEGF in ocular neovascularization .
Subsequently, several studies have demonstrated that VEGF is not only necessary but also sufficient to induce new vessels
growth in the eye .
Based on these robust scientific data, Napoleone Ferrara at Genentech (South San Francisco, CA) developed the first humanized
anti-VEGF antibody designed to block all VEGF isoforms (bevacizumab). This antibody was approved by the Food
and Drug Administration (FDA) in 2004 for the treatment of colon cancer in combination with chemotherapy. In the same year,
FDA also approved an RNA aptamer that binds and neutralizes VEGF165 (Pegaptanib - Macugen) for the treatment of neovascular
age-related macular degeneration (nAMD). Afterwards ranibizumab (Lucentis) in 2006 and aflibercept (Eyelea) in 2011
were approved for the same disease. Moreover, bevacizumab, although licensed only for treating different types of cancers, has
been used off-label in ophthalmology worldwild.
With time, the use of these drugs was extended to many ocular conditions, including pathologic myopia, diabetic retinopathy,
retinal vein occlusions, neovascular glaucoma, retinopathy of prematurity, idiopathic choroidal and corneal neovascularization.
Anti-VEGF therapy has improved visual outcomes in many eye diseases and has changed the standard of care in ophthalmology
in the last 15 years.
The aim of this thematic issue is to retrace the story of anti-VEGF therapy for ocular diseases, showing the results obtained
both in clinical trials and real life:
• Battaglia Parodi M. et al. discuss the use of anti-VEGF molecules to treat two important complications of retinal dystrophies:
choroidal neovascularization and macular edema ;
• Vilela M.A.P reviews the results of anti-VEGF therapy in retinal vein occlusions ;
• Giannaccare G. et al. highlight the efficacy and safety of the adoption of anti-VEGF agents into the daily clinical practice
for the management of corneal neovascularization ;
• Sorrentino F.S. et al. review recent advances by artificial intelligence for individualized anti-VEGF therapy in several eye
• The last paper (Campa C.) 5 new anti-VEGF drugs in an advanced stage of clinical development (conbercept, brolucizumab,
port delivery system with ranibizumab, abicipar pegol and faricimab) are presented .

Epigenetics is defined as heritable changes in gene expression that do not result from an alteration in the DNA sequence
itself . DNA/RNA modification, histone variants and modifications, and nucleosome positioning work together to determine
the epigenetic landscape of a cell. Until now, there is a growing awareness that epigenetic dysregulation plays a significant role
in many types of diseases, and that is fueling an increasing number of studies into drugs that target epigenetic regulators, and
several epigenetic targeted drugs have entered into clinic trials, including DNA methyltransferase inhibitor, bromo domain
reader inhibitor, histone acetylase or deacetylase inhibitor, histone methyltransferase or demethylase inhibitor, deubiquitinase
inhibitor or neddylation inhibitor.
Among these modifiers, several of them have been approved for clinical use. For examples, DNMT inhibitors 5-azacytidine
(5azaC) and 5-aza-2’-deoxycytidine (5azadC) have been approved for clinical use in haematological malignancies as myelodysplastic
syndrome (MDS), acute myeloid leukaemia (AML) and chronic myelomonocytic leukaemia (CMML) , vorinostat
(Zolinza, SAHA) earned FDA approval for the treatment of cutaneous T-cell lymphoma (CTCL) as histone deacetylase
(HDAC)1, 2, 3 and 6 inhibitor, panobinostat (Farydak) is the first HDAC inhibitor to gain approval for a nonlymphoma cancer,
a unique natural product Romidepsin isolated from the bacterium Chromobacterium violaceum gained approval to treat both
CTCL and peripheral T-cell lymphomas (PTCL) , tazemetostat (Tazverik, EPZ-6438, E7438) is the first epigenetic therapy
to gain FDA approval in a solid tumor by targeting the S-adenosylmethionine (SAM, AdoMet) binding pocket of H3K27 methyltransferase
Enhancer of zeste homolog 2 (EZH2) for epithelioid sarcoma treatment , et al. All these FDA approved drugs
indicate that epigenetic modifications are promising therapeutic targets for solid tumors and hematological malignancies.
Due to the fast-growing number of epigenetics and epigenetic targeted drugs, it is becoming a hot area in drug discovery for
cancer therapy. This thematic issue aims to review about epigenetic modification related drug target, drug discovery, assay development,
biological function, molecular modeling, target structure analysis, showing the progress of epigenetic modifications
as therapeutic targets.

Research on gynecological cancers particularly breast and tubo-ovarian cancers is evolving. Every year, randomized and
controlled trials in the area of women’s cancer provide considerable improvements in survival outcomes. Moreover, previously
known aggressive gynecological malignancies with poor outcomes are now reconsidered for novel treatments. However, drug
resistance is a serious challenge for this significant progress. Notably, predictive and prognostic biomarkers are increasingly
used to offer therapeutic decision-making in gynecological cancers especially with the remarkable advances in targeted therapies
in the last decade such as antiangiogenics, poly-ADP-ribose polymerase (PARP) inhibitors and immune-checkpoint blockers
[1-4]. With the emergence of precision medicine, the role of cancer biomarkers is promising as they enable the selection of
the best treatment options for the right patients. FDA-approved predictive biomarkers such as BRCA mutational status and programmed
death-ligand 1 (PD-L1) assays are enthusiastic examples of successful development of companion diagnostics. In this
special issue and as a part of the scientific activities of our recently launched Cancer Biomarkers Working Group, many basic
and clinical scientists from different countries were invited to participate in the review writing and share their experiences with
this hot topic. Various areas in cancer biomarkers were covered, including proteomic biomarkers, liquid biopsy, genomic signatures,
and other emerging biomarkers for several gynecological malignancies including breast cancer, ovarian cancer, endometrial
cancer, and other types. Biomarkers that have potential impact on predicting prognosis, survival, and therapy response are
discussed based on recently published findings from clinical trials and real-world studies. We strongly believe that our thematic
issue will provide clinically actionable information for evidence-based practice in modern cancer management and potential
perspectives for further research in gynecologic oncology.
In the present thematic issue of Current Drug Targets, we were fortunate to team up reputed scientists from clinical, translational,
and basic cancer research on gynecologic neoplasms to highlight important advances in this field of oncology:
1. Le Page et al. reviewed recent progress in biomarkers for serous ovarian cancer, particularly those who lead to new therapeutic
strategies encompassing PARP inhibitors, immunotherapy and antiangiogenic drugs and provided potential perspectives
for implementing personalized care in the future .
2. Lengyel et al. summarized the role of and clinical impact of PI3K-AKT-mTOR signaling in ovarian and endometrial cancers
and therefore, providing a rationale for further drug development in human clinical trials .
3. Tazzite et al. reviewed the genomic predictors of outcomes in triple-negative breast cancer with a special focus on platinumbased
chemotherapy which is the cornerstone in the management of this aggressive woman cancer .
4. Souid et al. reviewed predictive biomarkers for a promising marine-derived anticancer drug (trabectedin) that showed clinical
activity in various gynecological cancers with poor outcomes . The authors focused their discussion on the mechanisms
of action of trabectedin on multiple cancer hallmarks as well as the potential clinical outcomes from clinical trials and
the genomic predictors of therapy response.
5. Gouri et al. discussed the prediction of late recurrence and distant metastasis in early-stage breast cancer based on current
and emerging molecular signatures encompassing serum biomarkers and multigene profiling scores .
6. The last paper (El Bairi et al.) from our team aimed to discuss the potential of the human epididymis protein 4 (HE4) as a
promising prognostic biomarker for detecting recurrent epithelial ovarian cancer. This topic is highly important since the detection
of early recurrence considerably impacts the survival outcomes of this aggressive woman’s cancer .
Finally, we would like to express our sincere appreciation to the Editor in Chief Prof. Francis J. Castellino, editorial manager
K.M. Qamar, authors, reviewers, copy-editors and the entire editorial team of Current Drug Targets (Bentham Science Publishers)
for their professionalism and providing support to publish this thematic issue on this emerging topic in modern oncology.
The integrity of skeleton homeostasis is preserved by a balance maintaining between the activity of osteogenesis and osteoclastogenesis.
Document factors and stimuli have been determined involved in these two processes over the past century, however,
further understanding for exploring the physiological and pathological cellular processes are imperative requirement.
Here, in the current special theme issue, we have organize experts in the relevant fields to contribute novel understanding of
osteoclastogenesis, potential detective and therapeutic targets for skeleton diseases.
Five reviews included from the experts in the medical research and clinical therapeutic practice provided the novel understanding
for osteoclastogenesis relevant disease development and detection, osteoclastic cellular functional regulating,
intercellular signaling cascades and potential therapeutic natural compounds studies. Wang et al.  comprehensively reviewed
various diagnostic targets for its role diagnosis rate of spinal tuberculosis. In this review, authors specifically presented
the current novel progression of laboratory, imaging and gene detection in the diagnostic process of spinal tuberculosis
last several years.
Integrins in bone homeostasis, especially in osteoclastogenesis, have been taken as the novel and promising therapeutic drug
target for bone loss diseases, such as: osteolysis. However, its cellular mechanism is still elusive. Kong et al.  collected and
reviewed several novel studies on integrin and its sub-molecules ICAM-1 on bone homeostasis. Specifically, authors have focused
on the ICAM-1 which might play dual effects on osteoclastognesis by directly affecting the adhesion of mature osteoclast
and indirectly participates in the RANKL/RANK induced osteoclastic precursors differentiation. Although these results are still
conducted by a series of studies for further demonstration, exploring the role of ICAM-1 in osteoclastogenesis will definitely
provide promising therapeutic targets for treating bone loss diseases.
Besides that, inflammation is the most common pathology in many orthopedic diseases, such as: rheumatoid arthritis (RA),
osteoarthritis (OA) and inflammatory osteolysis. The leading factor of inflammation was considered as the differentiation of
monocyte and the polarization of macrophage. However, various cytokines and different cell models could regulate this progress
in some aspect. Liu et al. , therefore reviewed several cytokines and cell models, which lead to inflammatory orthopedic
diseases via regulating monocytes and macrophages. This review extensively explored the potential therapeutic and drug
targets for inflammatory induced bone diseases.
Liu et al.  reviewed the current novel research progress of RANKL and its downstream signaling pathways in bone cells,
and as an important drug target for its role in bone loss diseases. In this review, the authors also briefly introduced the current
application of several natural compounds for treating RANKL-mediated osteoclastic activation by modulating the RANKL signaling
pathway and their effects on the treatment and prevention of osteoporosis, OA and RA.
Finally, Wang et al.  extensively reviewed the naturally occurring compounds with less or no side effects, for their role in
the present clinical and fundamental study in osteoclastogenesis.
We hope this thematic issue will be beneficial for the vast readers and could serve as a good source of literature for scholars
in relevant study fields.
In continuation with computational advances in chronic diseases diagnostics and therapy – I , this part II consists of articles
which contribute to develop new ideas, algorithm design and rational drug discovery techniques to antiviral drug targets of
single-stranded ribonucleic acid (RNA) viruses, homeostasis in the cardiovascular system, ion channels as therapeutic targets
for type 1 diabetes mellitus and amyloid beta (Aβ) in Alzheimer's disease (AD).
Dinesh et al.  demonstrated that antiviral drug targets of single-stranded ribonucleic acid (RNA) viruses cause chronic
human diseases. RNA containing viruses associated with chronic diseases in humans are major threats to public health causing
high mortality globally. Extremely high mutation rates of RNA viruses make them deadliest and thus difficult to design an effective
drug. Chronic infections caused by human immunodeficiency virus (HIV-1) and hepatitis virus (HBV and HCV) lead to
acquired immunodeficiency syndrome (AIDS) and hepatocellular carcinoma, respectively, they are the primary cause of human
deaths. Effective preventive measures to limit chronic and re-emerging viral infections are absolutely necessary; and remains a
challenging issue. Antivirals usually inhibit different stages of the virus life-cycle, instead of killing them as in the case of the
bacterial antibiotics. Most often antiviral drugs are targeted against specific viral and host protein, whereas a few broadspectrum
drugs are available for targeting multiple viruses. In the recent past, an exponential increase in the number of available
three-dimensional protein structures and advancements in the in silico approaches, have paved the way to design and develop
several novel, highly specific small molecule inhibitors against protein drug targets. The present review briefly discussed
about selected single-stranded (ss) RNA genome containing human pathogenic viruses, causing chronic infections and are of
special importance for e.g. HIV-1, HCV, Flaviviruses, Ebola etc., their selected viral target proteins and an update about the
available small-molecule inhibitors or antivirals acting against them have also been discussed.
Singh and Karnik  clearly summarized homeostasis in the cardiovascular system maintained by physiological functions
of the renin angiotensin aldosterone system (RAAS). In pathophysiological conditions, over activation of RAAS leads to an
increase in the concentration of angiotensin II (AngII) and over activation of angiotensin type 1 receptor (AT1R) resulting in
vasoconstriction, sodium retention and change in myocyte growth. In the heart, it causes cardiac remodeling which results in
left ventricular hypertrophy, dilation and dysfunction which eventually leads to heart failure (HF). Inhibition of RAAS using
angiotensin converting enzyme inhibitors (ACEi) or angiotensin receptor blockers (ARBs) has shown to significantly reduce
morbidity and mortality due to HF. ACEi have been shown to have higher drug withdrawal rates due to discomfort when compared
to ARBs; therefore, ARBs are the preferred choice of physicians for the treatment of HF in combination with other antihypertensive
agents. Out of eight FDA approved ARBs, irbesartan and telmisartan are shown to have PPARϒ agonistic properties
resulting in improved insulin intolerance. Olmesartan treatment also improves insulin sensitivity and produces antiatherogenic
and anti-inflammatory effects in patients with diabetic nephropathy. All the ARBs demonstrate beneficial effects
similar to ACEi in the treatment of HF except the lower doses of losartan which leads to increase mortality in HF patients. Valsartan
in combination with sacubitril therapy has shown to be a promising therapy for HF. Eprosartan has an effect on the sympathetic
nervous system when compared to other ARBs and it is also able to reduce catecholamine release in animal models.
Therefore, eprosartan therapy may have an additional beneficial effect in the treatment of heart failure. However, eprosartan has
the shortest bioavailability (< 6 hours) when compared to other ARBs. Large numbers of studies that show beneficial effects on
animals have been reported but there are limited studies on humans. Hence, more human studies are warranted. Recently, crystal
structures of AT1R in inactive and active state structure have been solved. Using these crystal structures and cheminformatics
tools, exploring structures similar to eprosartan with an increase in bioavailability and affinity may enhance the treatment of
The review of Selvaraj et al.  demonstrated ion channels as therapeutic targets for type 1 diabetes mellitus. Ion channels
are integral proteins expressed in almost all living cells involved in muscle contraction and nutrient transport. It plays a critical
role in the normal function of the excitable tissues of the nervous system and regulates the action potential and contraction
events. Dysfunction of genes, which encodes ion channel proteins that disrupt the channel function, leads to a number of diseases,
which include type 1 diabetes mellitus (T1DM). Therefore, to understand the complex mechanism of ion channel receptors
it is necessary to facilitate the diagnosis and management of treatment. In this review, we summarizes the mechanism of
important ion channels involved in T1DM and the role in the regulation of insulin secretion along with the limitations for ion
channels as therapeutic targets. Furthermore, we discussed the recent investigations of mechanism regulating the ion channels
in beta cells, which suggest that ions channels are active participants in the regulation of insulin secretion.
Vijayan and C  discussed and summarized recent therapeutic strategies of amyloid beta (Aβ) in Alzheimer's disease
(AD). AD is one of the most common forms of dementia and has been a global concern for several years. Due to the multifactorial
nature of the disease, AD has become irreversible, fatal and imposes a tremendous socio-economic burden. Even though
experimental medicines suggested moderate benefits, AD still lacks an effective treatment strategy for the management of
symptoms or cure. Among various hypotheses which describe the development and progression of AD, the amyloid hypothesis
has been a long-term adherent to the AD due to the involvement of various forms of Aβ peptides in the impairment of neuronal
and cognitive functions. Hence, the majority of the drug discovery approaches in the past have focused on preventing the accumulation of Aβ peptides. Currently, there are several agents in the phase III clinical trials that target Aβ or the various macromolecules
triggering Aβ deposition. Here, the author discussed some of the state-of-the- art knowledge on the functional aspects
of the key players involved in the amyloid hypothesis. Furthermore, authors conferred about anti-amyloid agents present
in phase III clinical trials.
We hope multidisciplinary topics discussed with the theme issue will promote further discussions between the researchers
of computational advances in chronic diseases diagnostics and therapy.
As the guest editors, we would like to thank all the authors and co-authors for their excellent contributions. In addition, we
would like to thank a group of scientific experts in computation and chronic diseases diagnostics and therapy who offered their
strong comments and suggestions to improve the quality of this special issue. Finally, we would like to express our sincere appreciation
to the Editor in Chief Prof. Francis J. Castellino, editorial manager K.M. Qamar, copy-editors and all the editorial
staff in Current Drug Targets, Bentham Science Publishers for the excellent opportunity, and experience while working with
this thematic issue.
Recently, omics data explosion is transforming diagnostics research and healthcare industry, offering both opportunities and
challenges. Huge data of chronic disease diagnosis distributes equal IT challenges as in other fields, including data storage,
transfer, access control, and management. Another challenge is the computational modeling of complex biological systems.
High-throughput RNA-sequencing based transcriptomics, mass spectrometry based proteomics and nuclear magnetic resonance
spectroscopy-mass spectra based metabolomics are the most common popular statistical approaches that can be used for biomarker
detection of deadly diseases namely cancer, cardiovascular disease, and other chronic diseases, and to find out the composition
of material that the cells obtain from their micro-environment. Many recent studies have successfully applied network
models for describing and simplifying such complex systems. The proposed articles contribute to develop new ideas, algorithm
design and rational drug discovery techniques to chronic diseases (cancer and cardiovascular disease, etc.) diagnostics and therapy.
The first article demonstrated the importance of bioinformatics in anti-cancer drug discovery. High-throughput transcriptome
data were widely used in biomarker identification and drug prediction by integrating with drug-response data. In addition,
biological network theory and methodology were also successfully applied to the anti-cancer drug discovery, such as studies
based on protein-protein interaction network, drug-target network and disease-gene network. Moreover, the authors discussed
different bioinformatics approaches for predicting anti-cancer drugs and drug combinations based on the multi-omic data includes
transcriptomics, toxicogenomics, function genomics and biological network. Further, the authors overviewed the available
databases and current computational methods assisting in the development of novel cancer therapy strategies .
Loganathan et al.  summarized and discussed the computational and pharmacogenomics insights into hypertension treatment
towards rational drug design and optimization strategies. Among hypertension-related signaling mechanisms, the reninangiotensin-
aldosterone system is the leading genetic target for hypertension treatment. Identifying a single drug that acts on
multiple targets is an emerging strategy for hypertension treatment and could be achieved by discovering potential targets with
less mutation and highly conserved regions. Expanding pharmacogenomics research to include patients with hypertension receiving
multiple antihypertensive drugs could assist in identifying the genetic markers of hypertension. However, available
evidence on pharmacogenomics role in hypertension is limited and primarily focused on candidate genes. Genetic association
studies have identified single nucleotide polymorphisms affecting drug responses. To understand how genetic traits alter drug
responses, computational screening of mutagenesis can be utilized to observe drug response variations at the protein level,
which can help identify new inhibitors and drug targets to manage hypertension. Rational drug design facilitates the discovery
and design of potent inhibitors. However, further research and clinical validation are required before novel inhibitors can be
clinically used as antihypertensive therapies.
Fu et al.  systematically reviewed in light of this, the label-free quantification proteomics (LFQ) and diabetic marker selection
methods have been applied to elucidate the underlying mechanisms associated with insulin resistance, explore novel
protein biomarkers, and discover innovative therapeutic protein targets. Firstly, different popular quantification measurements
and proteomic quantification tools have been applied to the diabetes studies which are comprehensively discussed. Secondly, a
number of popular manipulation methods including transformation, pretreatment (centering, scaling, and normalization), missing
value imputation methods and a variety of popular feature selection techniques applied to diabetes proteomic data are overviewed
with objective evaluation on their advantages and disadvantage. Finally, the guidelines for the efficient use of the computation-
based LFQ technology and feature selection methods in diabetes proteomics are proposed. Finally, the authors have
provided guidelines for the researchers who are engaged in proteomics biomarker discovery and by properly applying these
proteomic computational advances, more reliable therapeutic targets can be found in the field of diabetes mellitus.
Calcium (Ca2+) ion is a major intracellular signaling messenger, controlling a diverse array of cellular functions like gene
expression, secretion, cell growth, proliferation, and apoptosis. This review aims to provide the key structural and mechanical
insights of stromal interaction molecule (STIM), ORAI1 and other molecular modulators involved in Ca2+ release-activated
Ca2+ (CRAC) channel regulation. Understanding the structure and function of the protein is the foremost step towards improving
the effective target specificity by limiting their potential side effects. The major mechanism controlling the Ca2+ homeostasis
is store-operated CRAC channels. Following Ca2+ depletion in the Endoplasmic reticulum (ER) store, STIM1 interacts with
ORAI1 and leads to the opening of the CRAC channel gate and consequently allows the influx of Ca2+ ions. A plethora of
studies reported that aberrant CRAC channel activity due to loss-or-gain-of-function mutations in ORAI1 and STIM1 disturbs
this Ca2+ homeostasis and causes several autoimmune disorders. Hence, it is clearly defined that the therapeutic target of
CRAC channels provides the space for a new approach to treat autoimmune disorders. Herein, the authors mainly focused on
the structural underpinnings of the CRAC channel gating mechanism along with its biophysical properties that would provide a
solid foundation to aid the development of novel targeted drugs for an autoimmune disorder. Finally, the immune deficiencies
caused due to mutations in CRAC channel and currently used pharmacological blockers with their limitations are briefly summarized
The last article discussed about the computational strategy revealing the structural determinant of ligand selectivity towards
highly similar protein targets . Poor selectivity of drug candidates may lead to toxicity and side effects accounting for as high
as 60% failure rate, thus selectivity is consistently significant and challenging for drug discovery. To find highly specific small
molecules towards very similar protein targets, multiple strategies are always employed, including (1) To make use of the diverse
shape of binding pocket to avoid steric bump; (2) To increase binding affinities for favorite residues; (3) To achieve selectivity
through allosteric regulation of target; (4) To stabilize the inactive conformation of protein target and (5) To occupy
dual binding pockets of single target. Here, the authors summarized computational strategies along with examples of their successful
applications in designing selective ligands, with the aim to provide insights into ever-diversifying drug development
practice and inspire medicinal chemists to utilize computational strategies to avoid potential side effects due to low selectivity
We hope that multidisciplinary topics discussed with the theme issue will promote further discussion between the researchers
of computational advances in diagnostics and therapy of chronic diseases.
As the guest editors, we would like to thank all the authors and co-authors for their excellent contributions. In addition, we
would like to thank a group of scientific experts in computation and chronic diseases’ diagnostics and therapy, who offered
their strong comments and suggestions to improve the quality of this special issue. Finally, we would like to express our sincere
appreciation to the Editor in Chief Prof. Francis J. Castellino, editorial manager K.M. Qamar, copy-editors and the entire editorial
staff of the Current Drug Targets, Bentham Science Publishers for the excellent opportunity, and the wonderful experience
we had while working with this thematic issue.
The incidence and prevalence of Inflammatory bowel diseases (IBD), represented by Crohn's disease (CD) and ulcerative
colitis (UC) are globally increasing over the past few decades .
Surgery is still needed in a significant number of IBD patients and represents an important therapeutic tool in the management
of both diseases [2, 3]. Surgical rates are decreasing over time following the overspread use of biological agents, such as
anti-TNFs, anti-IL-23 or anti-integrins . However, proper care and a timely indication for these new agents vary across the
world . In parallel, the evolving role of surgery in IBD management is noteworthy . In 2019, management of IBD and its
disease complications often require a combined medical and surgical approach.
As a consequence, surgical participation interacting with gastroenterologists in the care of IBD patients is essential in the
multidisciplinary management of CD and UC. The correct timing of surgical indication in IBD is essential to maximize the
benefits for the patients. As an example, it is not uncommon to see patients with fibrotic disease, which can be managed surgically,
being treated with medical therapy. This can be observed in centers where there is no interaction between colorectal surgeons
and IBD gastroenterologists, where patients sit in an uncomfortable position between both specialties with no proper
communication between the specialists. Clearly, the efficacy of medication will be lower in these situations, leading to a delay
in surgical indication, with malnourished patients, resulting in higher postoperative complication rates.
In this issue of Current Drug Targets, entitled “Medical-surgical approach in inflammatory bowel disease: doing it together!",
several specific situations where the joint care of IBD patients including surgeons and gastroenterologists is optimized
are discussed in detail. Perioperative therapy with different drugs, as steroids, immunomodulators and biologics, is explored in
different scenarios. The evidence clearly demonstrates that preoperative steroids do worsen postoperative outcomes in both CD
and UC. Immunomodulators, such as azathioprine, can be safely used in the perioperative period, with no impact on postoperative
infections. Evidence with different classes of biologics also demonstrates the controversy regarding these agents, where
conflicting evidence exploring the impact of anti-TNFs, anti-integrins and anti-interleukins in postoperative complications
demonstrates the need for a tailored approach in a case-by-case basis. When to initiate or re-initiate biologics after surgery in
CD? This is also another example of the need for a close relationship between medical and surgical care specialists.
Other situations in IBD also benefit from multidisciplinary team (MDT) frequent discussions. A perfect example of that is
the management of perianal CD, usually a challenging scenario for patients and health care specialists. Several sequential steps
are needed aiming better outcomes to these patients. A proper diagnosis, with adequate imaging tests, followed by early referral
for surgical preparation with curettage of fistula tracks, placement of setons and eradication of perianal sepsis before initiation
of biological therapy, exemplify different specialties that are involved in the management of this important phenotype of CD.
Radiologists, gastroenterologists and surgeons sitting together, having joint clinics, and discussing each case on a multidisciplinary
basis, can lead to optimized outcomes by improving patients' quality of life, which is one of the important treatment goals
in this scenario.
In UC, the need for joint efforts between gastroenterologists and surgeons can also improve the outcomes for patients. Usually,
patients are exhausted with multiple medications, with an impaired nutritional status when they finally have referrals for
colectomy. This often impacts a change in the surgical strategy, where staging operations and delaying pouch construction can
represent a safer alternative, with decreased major postoperative complications. Involvement of surgeons early in admissions
for severe colitis, aiming early recognition of complications, such as toxic megacolon and blocked perforations can also contribute
for proper timing of surgery. It is known that a delay in colectomy in this specific scenario increases significant morbidity
and mortality, and this can be avoided by a proximal relation between specialists in the MDTs. Therefore, discussion regarding
the proper timing of surgery and the specific medications used perioperatively can lead to individualized decisions and need
to be discussed between different specialties also in UC. (Table 1) summarizes some of the main indications and specific advantages
of joint MDT care in IBD.
The 21st century has seen a massive spring up in the applications of nanotechnology. Incorporation of functionalized and
modified nanostructures in various biomedical applications has generated significant research interest. The applications of
nanotechnology in medicine and biomedical engineering are vast and span areas such as implant and tissue engineering,
diagnosis and therapy. There is a need of designing nanotools, which can respond to the needs of health problems and develop
more efficient biomedical approaches.
The present special issue includes four articles with the goal of reviewing the recent developments in nanobiotechnology
with special emphasis on novel tissue engineered scaffolds and the development of nanonetworks as new communication tools
for medical approaches. Nanomaterials are also at the leading edge of the rapidly developing field of nanotechnology. In particular,
Marzo J.L. et al. started the thematic issue with a very innovative perspective. Marzo J.L. et al. reviewed the IT systems
and networks’ role in medical applications and how nanostructures can contribute medical services. As a perspective of IT on
medical field, Laromaine, A. and Roig A. reviewed biomedical application by challenging materials, which can help in tissue
treatment. In fact, the paper is focused on new developments in organic material such as cellulose to repair epithelial tissues. In
their article, Dean D. et al. focused on tissue regeneration as well. However, their focus as not only on materials which are synthetic
and not organic, but on new technologies such as 3D printing methods. A combination of materials and technologies has
been summarized to rebuilt biomedical implants. Finally, Puig M et al. reviewed the potential of different biocompatible materials
such as PCL and PLA to manufacture scaffolds for cell culture. Cell culture in 3D mimics better the human body cells,
thus it helps in the cells enrichment, and thus, the cancer cells characterization with the idea of targeting new treatments.
Overall, the aim of this issue is to offering new data to investigators to help them realize about the most recent
developments in the field of applied nanomaterials in biomedicine from different perspectives. In addition, the safety aspects in
the applications of nanotechnology to biomedical practical applications have also been examined.
We greatly acknowledge the Editor-in-Chief, Francis J. Costellino and Bentham Science Publisher for their continuous
encouragement and professional support throughout the preparation of this special issue. Finally, we would like to thank all the
authors and all the referees for their availability and their thorough evaluations of the articles published in this issue.
With the development of high-throughput sequencing techniques, more and more sequencing data is available,
including genomics reads, transcriptomes data, and proteomics sequences, which provide us an opportunity for
disease treatment and prevention that takes into account individual variability in environment, lifestyle and genes
for each person. Thus, it is critical to develop various methods in the identification of drug targets. Application of
computational methods in drugs targets discovery is more and more popular because these techniques can extract
the essential characteristics of research object and improve accuracies of models, which is needed by all biological
scholars. This special issue will focus on various aspects of the development and application of machine learning
techniques in drug targets recognition analysis.
The complete perspectives of bio-psycho-social standing of pharmacological agents are the key-features in the observation
how a drug act. This thoughtful approach is indeed imperative when managing patient's anticipation and expectation, especially
during the disease process and recuperation process. In clinical practice, the core knowledge on the art of prescribing drugs and
understanding their current drug targets in vivo and vitro can be very helpful. Hence, it may help the physician to choose the
right pharmacological agents in the therapeutic alliance.
Research has robustly documented the role of the bio-psycho-social contributing factor, and how they may influence an
individual’s experience of receptor targets for the prescribed drugs. The purpose of bio-psycho-social contribution, i.e. relationships
between drug-drug interactions are worth to be understood when prescribing antidepressants among patients with erectile
dysfunction, as the former is associated with a significant sexual dysfunction. Sexual dysfunction is also seen among women
and the role agent to promote sexual desire is considered pivotal in the intimacy-relationship domain. The cognition and emotional
states are essential in managing patients with morbid jealousy, the ‘green-eyed monster’. Cognitive-emotion domain is
also important in addressing problems of a substance-use disorder. Kratom, one of the prevalent substance-use disorders in
South-East Asian countries are an example of the problematic dilemma in an attempt to balance between the side-effects and
the benefit as a pain-killers. Another substance-use problem of nicotine dependence will be discussed in this segment of thematic
issue, especially in relation to patients with mental-health issues. We also discussed the role of bupropion in helping patients
with an Adult Attention Deficit Hyperactive Disorder, besides prescribing a psychostimulant to reward the pleasure centre
of the brain. Changes in the body, as the result of menopause also will be outlined on the role of Phytoestrogens, the Thermoregulatory
The holistic standpoint of biopsychosocial importance of mediation is crucial in terms of the perception regarding how the
psychopharmacological agent acts. This understanding is indeed important when dealing with patient's expectation and hope,
specifically during their illness and recovery process. In clinical setting, the fundamental knowledge of know-how art of prescribing
medication and dietary advice can be of great help in the real-world practice of medicine. Subsequently, this manoeuvre
may influence the choice of the pharmacological agents, dietary choice of intake and managing the adverse-effect of the
existing drug intervention routine. The relationship of the mind-body is well described in the literature especially in the context
of pharmacological therapy. The relationship is important in order to be understood for the management of patients in the clinical
Research studies have been conducted to ascertain the role of the psychosocial contributing factors, and how they may influence
an individual’s experience of drug targets. In this thematic issue, the articles focussed on the role of drug targets, which
was augmented by the emotional-cognitive and behavioral mediation in enhancing the effects of biological therapy. Emotionalcognitive
determinants may influence the processing of neurochemical actions, e.g. the dopamine-oxytocin-nitric oxide neural
pathway in patients who were given treatment in order to improve their sexual intimacy with his or her partner. These determinants
are also relevant while elaborating the role of psychopharmacological agents in alleviating the patient’s somatic symptoms.
Behavioural modification advice may help patients regain their self-confidence in their journey to recovery, despite petite
guidance given by the clinician.
The purpose of biopsychopsychological input, i.e. intimacy-relationship, cognition and emotional states is important in
helping the patient’s self-esteem with successful treatment of the PDE-5 inhibitors. Selecting the right psychopharmacological
agents to reduce the sexual-adverse effect of drugs is essential in patients with both depression and schizophrenia. The roles of
new novel antidepressants are portrayed in their multi-modality function to treat depression. Antidepressant’s effect on managing
physical symptoms is important. The stress model diathesis of alcohol in mental health was underlined with the perspective
of neuronal basis of cognition memory.
In the present thematic issue, the association of serotonin selective reuptake inhibitors and female sexual dysfunction was
discussed with special emphasis on its treatment. Interesting articles on the antinociceptive effect of Mitragyna speciosa, the
phosphodiasterase 5-inhibitors (PDE-5i) for erectile dysfunction, the recent approaches on treatment of alcohol addiction, the
neurobiology of hypersexuality and its treatment, role of atypical antipsychotics in sexuality, treatment of anxiety disorders
with Vortioxetine and the role of dietary compounds in the treatment of anxiety disorders were highlighted. Last but not the
least, the present issue also focused on the use of antidepressants for physical and psychological symptoms in cancer and discussed
the dietary issue in the biopsychopsychological context of treatment, which included tocopherol and tocotrienol.
Abdominal aortic aneurysm (AAA) is a common inflammatory cardiovascular disease among the elderly . Since the
1990s, several animal models have been developed and basic researches have been conducted to understand the pathological
conditions . Many molecules and drugs that inhibit the activity of MMPs and suppress the formation of aortic aneurysms
were found in these animal models . In particular, those which inhibit c-Jun N-terminal kinase and suppress the activity of
MMPs, regressed aortic aneurysms in animal models, and were considered as promising therapeutic drugs . However, the
pathogenesis of AAA still remains unknown. Therefore, “no” drug treatments of AAA have been approved in clinical practice,
so that surgery is currently the only treatment of AAA .
The established animal models of AAA have been employed to advance the understanding of the mechanisms in order to
identify potential treatment targets . And the models are constructed by inducing inflammatory responses by using substances
such as Angiotensin II, CaCl2 and elastase, because inflammation of the medial region and vulnerable vessel walls are
recognized as the main cause of AAA development . However, the upstream factor of inflammation associated with the development
of AAA remains unknown. More importantly, there is debate that there are discrepancies in the pathological findings
between humans and established animal models used in AAA research. Similarities in the pathogenesis between human
AAA and animal AAA models are essential for the development of pharmacological treatments.
In order to have a better opinion of experimental study using animal model and to introduce novel methodology and tool for
AAA samples, we would like to have specials relating to present and future of pharmacological therapy for AAA. At present,
there are few clinical trials associated with AAA. However, several pharmaceutical companies are interested in testing therapies
for AAA. There are as yet not few researchers studying AAA. I believe that lots of readers take a considerable interest in AAA
research through the special feature.
Cardiometabolic syndrome refers to a group of cardiometabolic risk factors that greatly increase the risk for cardiovascular
diseases and other health problems. As per the consensus of the National Heart, Lung and Blood Institute (NHLBI) and American
Heart Association (AHA), cardiometabolic syndrome is a constellation of 3 or more of the following risk factors: abdominal
obesity, high triglycerides, dyslipidemia (low- and high-density lipoprotein cholesterol), hypertension, and elevated fasting
blood glucose . At this time, the therapeutic strategies are mainly aimed at the management of individual risk factors including
dyslipidemia, hypertension and diabetes . With the ever-rising prevalence of cardiovascular anomalies including cardiac
hypertrophy, hypertension, arrhythmias, and heart failure in cardiometabolic diseases , it is pertinent to identify and develop
novel diagnostic and therapeutic techniques to better manage the cardiovascular risk in cardiometabolic diseases. For example,
the recent application of the new class of anti-diabetic drugs sodium glucose co-transporter 2 (SGLT2) inhibitors has greatly
improved the cardiovascular benefits for drugs targeting cardiometabolic syndrome . Here we will present this special issue
of “Current Drug Target” on “Drug discovery and development in the management cardiometabolic diseases” to discuss a
number of new therapeutic options in the field. Our enthusiasm for this topic came from the profound opportunities for novel
therapeutic concepts in cardiometabolic diseases. It is essential to broaden our understanding for the precise mechanisms behind
these therapeutic modalities in the management of cardiometabolic diseases.
In the first review article of this series, Li and colleagues discussed the pivotal role of ubiquitin (Ub) and ubiquitin-like proteins
(UBLs)-associated post-translational modification in the regulation of protein function in cardiac cells. Conjugation of Ub
or UBLs to target proteins may modulate both physical and physiological properties of protein substrates, thus governing a
number of disease processes including cardiac diseases . In the second article, Zhu and Zhang reviewed how the interplay
between apoptosis and autophagy controls cell death or proliferation in vascular smooth muscle cells, neointimal hyperplasia
and restenosis pathogenesis . In the third article of this series, the authors also shed light on the conservative autophagy
process to provide some valuable insights into the potential mechanism of autophagy in the onset and development of rheumatic
autoimmune diseases . In the fourth article, the authors discussed the forefront of pancreatic cancer treatment, and the
potential role of pargeting autophagy in therapeutics against pancreatic cancer . Autophagy has recently drawn some attention
as a novel drug target in the management of cardiovascular and metabolic diseases , although the potential of autophagy
in drug development may be a daunting process for cardiometabolic and other human disorders. In the fifth review, Janardhanan
reported that endocrine disrupting chemicals impair physiological homeostasis, leading to developmental and reproductive
abnormalities. Ample evidence has validated the significance of exposure to endocrine disrupting chemicals in cardiometabolic
disorders . In the next article, Chen and associates discussed the promises of ApoE4 as a potential target for the
management of coronary heart disease and Alzheimer's disease. Carriers of the ApoE4 allele seem to display hypercholesterolemia,
which would accelerate the progression of coronary atherosclerosis and Alzheimer’s disease. They have discussed
the interconnection between coronary heart disease and the devastating neurodegenerative diseases . In the seventh article,
Ceylan and colleagues discussed the SGLT2 inhibitors as the new class of antidiabetic agents, and possible advantages of the
new SGLT2 inhibitors over the traditional hypoglycemic agents in the control of body weight, blood pressure and hyperuricemia
. In the eighth article, the authors revisited the recent clinical trials on SGLT2 inhibitors including empagliflozin and
canagliflozin and highlighted the cardiovascular benefits of these SGLT2 inhibitors in type 2 diabetic patients. They dissected
the regulatory roles of SGLT2 inhibitors in energy metabolism and cardiovascular function, and factors that may compromise
the therapeutic benefit . In the ninth article, Obradovic and colleagues discussed the potential role of proprotein convertase
subtilisin/kexin type 9 (PCSK9) in the treatment of hypercholesterolemia. They also highlighted the potential opportunities and
challenges in targeting PCSK9 in the clinical settings . In the next article, Kobayashi and colleagues discussed the role of
iron as a risk factor for coronary artery disease, in particularly whether iron is toxic or not in patients with coronary heart diseases
. In the last article of this series, Feng and colleagues from Fuwai Hospital reviewed the recent concept and knowledge
of non-cardiomyocytes in the regulation of cardiomyocyte proliferation and differentiation during postnatal cardiac regeneration,
in an effort to identify potential targets for the treatment of heart failure .
Although our special issue has updated some of the recent hot topics in the understanding of cardiometabolic diseases, it
leaves behind much more unanswered questions that remain to be explored with intense research effort in future. First, cardiometabolic
syndrome is not a disease entity, thus making it rather challenging to formulate a unified therapeutic regimen for a
given individual with cardiometabolic diseases. Second, experimental animal or cell culture models for cardiometabolic diseases
may not be able to recapitulate the true pathological changes under clinical settings. Therefore, the translation of knowledge
from bench-side to the bed-side practice remains a long journey. Third, given the complexity and multiple independent
risk factors in the etiology of cardiometabolic diseases, it is almost impossible to rule a particular intervention to be superior
than others, letting alone the option of life style modification as a key element in the management of cardiometabolic syndrome
(not included in our special issue considering the central theme). We would hope that this special series will help the scientific
society to identify novel therapeutic targets or concepts in the management of cardiometabolic diseases.
The holistic perspective of bio-psychosocial dimension of intervention is important to understand how the psychopharmacological
agent works. In this thematic issue, we highlight the role of psychological and behavioural intervention to augment the
effects of current drug targets. The articles highlight the role of psychological perspective in understanding emotional responses,
cognitive-memory and vitality of the biological therapy.
The role of psychological input, i.e. psychosexual and intimacy is vital to help the patient regain full recovery with the PDE-
5 inhibitors treatment. Cognitive and counselling will enhance the treatment for women with vaginismus. Vitamin D and hormonal
preparation improves the individual's vitality. Regarding cancer patients, methylphenidate have a role for better recovery
in the treatment outcome. In addiction and Alzheimer disease, the common pathway for the human memory is better understood.
Knowledge of the pharmacokinetic of drug will surely improve the treatment strategy for psychotropic agents in psychosis.
Inflammatory Bowel Disease (IBD) is a frequent, chronic, incurable and disabling condition . Personalized medicine is a
unique opportunity to face these health challenges in the new millennium. The use of personalized medicine will allow the physician
to select the best treatment protocol and will avoid passing the expense and risks of unnecessary medical treatments that
are not properly metabolized nor are the cause of disease complications. The identification of predictors (biomarkers) of efficacy
and safety of biologics as well as predictors of disease progression is a prerequisite to the development of strategies tailored
to each individual. It is worth noting the quasi-absence of biomarkers of responsiveness to therapies despite the relatively
limited success of biologicals available to treat IBD. Identifying predictors of disease progression and of safety/efficacy of biologics
is the next step toward personalized medicine before determining the right dose for a patient, helping to avoid hazards.
In this issue of Current Drug Targets dedicated to personalized medicine in IBD, we review many aspects of the future of
IBD management and discuss whether we can predict disease course with clinical factors  and improve the safety profile of
drugs  using a personalized approach. Non-invasive monitoring of IBD patients and the clinical utility of therapeutic drug
monitoring of biologics and serological markers in clinical practice remain a matter of debate in 2016 [4-7]. The final aim of
personalized medicine is to improve quality of care of IBD patients. This will lead to evolving treatment algorithms in the preand
post-operative setting for these patients [8-11]. Embarking the patient into the management plan is the key to success. In
this regard, personalized psychological treatment of IBD patients should be systematically considered in routine practice.
