The spiro[pyrrolidine-3, 3´-oxindole] moiety is present as a core in number of alkaloids with substantial biological activities. Here in we report design and synthesis of a library of compounds bearing spiro[pyrrolidine-3, 3´-oxindole] motifs that demonstrated exceptional inhibitory activity against the proliferation of MCF-7 breast cancer cells. The(More)
Herein we have reported design, synthesis and in vitro biological evaluation of a library of bicyclic lactams that led to the discovery of compounds 6 and 7 as a novel class of α-glucosidase inhibitors. They inhibited α-glucosidase (yeast origin) in a mixed type of inhibition with an IC50 of ∼150 nM. Molecular docking studies further substantiated screening(More)
Nitrogen heteroarenes form an important class of compounds which can be found in natural products, synthetic drugs, building blocks etc. Among the diverse strategies that were developed for the synthesis of nitrogen heterocycles, oxidative dehydrogenation is extremely effective. This review discusses various oxidative dehydrogenation strategies of C-C and(More)
An exceptional oxone mediated tandem transformation of 2-aminobenzylamines to 2-substituted benzimidazoles is reported. It occurs at room temperature with aromatic, heteroaromatic, and aliphatic aldehydes. In this reaction initial condensation of 2-aminobenzylamine with appropriate aldehydes afforded a tetrahydroquinazoline intermediate which underwent(More)
DNA topoisomerase I is a potential chemotherapeutic target. Here, we designed and synthesized a library comprising of hydantoin and thiohydantoin derivatives and tested them against human and Leishmania Top1. One of the thiohydantoin compounds with substituted thiophenyl as the central moiety (compound 15) exhibited potent inhibition of human Top1 (HTop1)(More)
Natural product-inspired libraries of molecules with diverse architectures have evolved as one of the most useful tools for discovering lead molecules for drug discovery. In comparison to conventional combinatorial libraries, these molecules have been inferred to perform better in phenotypic screening against complicated targets. Diversity-oriented(More)
Malaria a global pandemic has engulfed nearly 0.63 million people globally. It is high time that a cure for malaria is required to stop its ever increasing menace. Our commentary discusses the advent and contribution of genetic algorithm (GA) in the drug discovery efforts towards developing cure for malaria. GAs are computational models of Darwinian(More)
