Abstract
The extensive adaptability of dendrimer-based contrast agents is ideal for the molecular imaging of organs and other target-specific locations. The ability of literally atom-by-atom modification on cores, interiors, and surface groups, permits the rational manipulation of dendrimer-based agents in order to optimize their physical characteristics, biodistribution, receptor-mediated targeting, and controlled release of the payload. Such modifications enable agents to localize preferentially to areas or organs of interest for facilitating target-specific imaging as well as assume excretion pathways that do not interfere with desired applications. Recent innovations in dendrimer research have increased agent directibility and new synthetic chemistry approaches have increased efficiency of production as well as led to the creation of novel dendrimer-based contrast agents. In addition, by taking advantage of the numerous attachment sites available on the surface of a single dendrimer molecule, new synthetic chemistry techniques have led to the development of multimodality magnetic resonance, radionuclide, and fluorescence imaging agents for molecular imaging. Herein we discuss advances in dendrimer-based contrast agents for molecular imaging focusing mainly on the chemical design as applied to optical, magnetic resonance, computer tomography, radionuclide, and multi-modality imaging.

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
