Abstract
Transition metal complexes with terpyridine ligands have attracted a widespread interest with respect to biomedical applications: [(tpy)PtCl]Cl and [(tpy)RuCl3] are potent anti-tumor agents with activities comparable to those of cisplatin and carboplatin. The RuII complexes feature a high potential as reactive probes for DNA oxidation; whereas, luminescent IrIII, PtII or EuIII complexes have been utilized in biolabeling applications. Besides complexes based on heavy second or third row transition metal ions, remarkable results have been obtained with respect to the development of new types of metallodrugs, based on the naturally more abundant and intrinsically less toxic first row transition metal ions (e.g. FeII, CuI/II, ZnII). The perspective of these complexes in particular with respect to future biomedical applications in chemotherapy and cleavage of nucleic acids is evaluated in this review.

Chemistry Based on Natural Products for Therapeutic Purposes
The development of new pharmaceuticals for a wide range of medical conditions has long relied on the identification of promising natural products (NPs). There are over sixty percent of cancer, infectious illness, and CNS disease medications that include an NP pharmacophore, according to the Food and Drug Administration. Since NP ...read more
Current Trends in Drug Discovery Based on Artificial Intelligence and Computer-Aided Drug Design
Drug development discovery has faced several challenges over the years. In fact, the evolution of classical approaches to modern methods using computational methods, or Computer-Aided Drug Design (CADD), has shown promising and essential results in any drug discovery campaign. Among these methods, molecular docking is one of the most notable ...read more

From Biodiversity to Chemical Diversity: Focus of Flavonoids
Flavonoids are the largest group of polyphenols, plant secondary metabolites arising from the essential aromatic amino acid phenylalanine (or more rarely from tyrosine) via the phenylpropanoid pathway. The flavan nucleus is the basic 15-carbon skeleton of flavonoids (C6-C3-C6), which consists of two phenyl rings (A and B) and a heterocyclic ...read more
