Combinatorial Chemistry & High Throughput Screening - Volume 19, Issue 10, 2016

Background: Docking allows to predict ligand binding to proteins, since the 3D-structure for the target is available. Several docking studies have been carried out to identify potential ligands for drug targets. Many of these studies resulted in the leads that were later developed as drugs. Objective: Our goal here is to describe the development of an integrated computational tool to assess docking accuracy and build new s Read More

Background: Visceral leishmaniasis (VL) is a tropical neglected disease, which encounters poorest of poor people living in Asia, Africa and Latin America; causing the mortality of more than 30,000 people worldwide. The armamentarium for the treatment of VL cases is limited and continuously facing decreasing of efficacy for existing drugs. Ornithine decarboxylase (ODC) is one of the interesting drug targets in Leis Read More

Background: Rather than a Janus Kinase 2 inhibitor (ruxolitinib), a specific thrombopoietin receptor (TpoR) inhibitor would be more specific for the treatment of myeloproliferative neoplasms due to TpoR mutations. Objective: A cell-based phenotypic approach to identify specific TpoR inhibitors was implemented and a library of 505,483 small molecules was screened for inhibitory effects on cells transformed by TpoR mutants. R Read More

Aim and objective: Rheumatoid Arthritis (RA) is a progressing autoimmune inflammatory disease of joint, hallmarked by inflammation, pain and atrophy of bones. Toll-like receptor 5 (TLR5) is a novel inflammatory mediator in RA, and TLR5 inhibitors are speculated to have a therapeutic potential for the treatment of RA. Material and method: Here we applied fragment pharmacophore-based virtual screening to identify n Read More

Aim and objective: This study aimed to quantify phenolic compounds in ethyl acetate and n-butanol extract of Centaurea choulettiana Pomel (Asteraceae) leaves and flowers; compare the antioxidant activity of their extracts, identification and quantification of their phenolic acids. Materials and methods: Both organs extracts of Centaurea choulettiana Pomel were investigated and evaluated for their potential antiox Read More

Background: Selenocyanate derivatives have been recently presented as potent anti-leishmanial agents. Objective: In this research, thirty five selenocyanate and diselenide compounds were subjected to docking studies and compared to Edelfosine and Miltefosine as reference drugs and then molecular dynamics (MD) simulation analysis. Methods: Desired Selenocyanates were built using the HyperChem program and doc Read More

Background: Tuberculosis (TB) kills over 1.5 million people per year despite the available anti-TB drugs. The long duration needed to treat TB by the current TB drugs, which target the essential cellular activities, inevitably leads to the emergence of drug-resistance. The emergence of drug-resistant TB prompts for an urgent need for new and more effective drugs. Objective: The response regulator PhoP, an essential virulen Read More

Aim and objective: Tetrahydrobenzo[b]pyran derivatives are considered as a special class in drug research because of their various biological and pharmacological benefiting usages. In the current work, we developed new synthetic methods for the preperation of tetrahydrobenzo[b]pyran derivatives using arylaldehydes 1, malononitrile 2 and dimedonein 3 in the presence of caffeine as catalyst as a cheap, easily accessible, Read More

Background: The Rab family proteins are involved in membrane trafficking, cell growth and differentiation. Rab38 is implicated in the biogenesis of melanosomes that help in the synthesis, storage and transport of melanin pigments. The Rab38 protein is overexpressed at the RNA level in melanoma cancer. Aim and objective: The protein Rab38 is targeted for identification of novel antagonists as cancer drug candidates. M Read More
