Abstract
The identification of HIV-1 protease (HIVp) as a target for therapeutic intervention against AIDS was soon followed by major efforts to understand its substrate specificity, reaction kinetics and three-dimensional structure, both in the free state and in complex with a number of ligands including substrate mimics, products, and inhibitors. On the whole these studies have been extremely successful and have had a major impact on our understanding of ligand-receptor interactions and enzyme inhibition mechanisms. HIVp has also become a paradigm for the development and testing of new drug-design methodologies both in vitro and in silico. Even though thousands of potential HIVp inhibitors exhibiting amazing chemical diversity have been synthesized or identified from natural sources, only a few have turned out to be useful for human therapy. Although the alternative goal of preventing enzyme dimerization has been achieved as a proof of concept, this approach has not yet yielded a clinical candidate. The review covers the general strategies that led to some of the most useful inhibitors, the reasons for our limited success in effectively inhibiting this retroviral target in a clinical setting, current progress with second-generation inhibitors, and new avenues for research.

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
Drug Discovery in the Age of Artificial Intelligence
In the age of artificial intelligence (AI), we have witnessed a significant boom in AI techniques for drug discovery. AI techniques are increasingly integrated and accelerating the drug discovery process. These developments have not only attracted the attention of academia and industry but also raised important questions regarding the selection ...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
