Medicinal Chemistry and Drug Discovery

New chemical entities as EGFR inhibitors, DNA repair inhibitors, Topoisomerase inhibitors and mitochondrial death pathway stimulator, Xanthine Oxidase inhibitors, novel 2-substituted benzoxazole derivatives as COX-2 enzyme inhibitors and PDE-4 inhibitors are developed. RK-33, which first emerged as a DDX-3 inhibitor has a broad spectrum of anticancer effects (Organic Letters 2008, 10, 4681-4684, International Publication Number: WO 2010/039187 (https://patentscope.wipo.int/search/en/detail.jsf?docId=WO2010039187), ACS Med. Chem. Lett. 2011, DOI: 10.1021/ml100281b).

Diagnostic agents

Pd-catalyzed cascade reaction for the synthesis of fluorescent indazolo[2,3-c]quinazolines with high quantum yield and excellent photostability was developed. Its application is explored in live-cell imaging, which exhibited cytoplasmic and mitochondrial specific staining with no toxicity (J. Org. Chem. 2019, 84, 3817−3825; Patent No. 201811028230).

Green Chemistry and methodology development

Recently a “carbene mediated-Pictet Spengler reaction” for the first time for the synthesis of imidazo[1,2-a]quinoxaline compounds (Org. Chem. Front., 2018, 5, 3526-3533., Indian Patent No. 201611014161) is revealed under Microwave conditions. Novel methodologies were established by using re-usable heterogeneous catalysts such as HClO4 adsorbed on SiO2, HBF4 adsorbed on K-10/KSF clays or Lewis acid catalysts such as Cu(BF4)2·xH2O and Zn(ClO4)2·6H2O with their electrophilic activation potential or water or SDS-water having dual-activation power. Microwave-assisted catalyst-free synthesis of 2-substituted benzoxazoles and 4-aminoquinoline derivatives and pyrazolo(1,5-c)quinazoline were also developed.
