Synthesis and inhibition studies towards the discovery of benzodiazepines as potential antimalarial compounds

The target-based discovery of therapeutics against apicoplast, an all-important organelle is an overriding perspective. MEP pathway, an accredited drug target provides an insight into the importance of apicoplast in the survival of the parasite. In this study, we present the rational design strategy employing sustainable catalysis for the synthesis of benzodiazepine (BDZ) conformers followed by their biological evaluation as prospective inhibitors against the potential target of the IPP pathway, 1-deoxy-D-xylulose-5-phosphatereductoisomerase (DXR). The study reported the inhibitory profile of 8c and 6d against the quintessential step of the only drug target in the erythrocytic stages of parasite development. The potential compounds were identified to represent a novel class of inhibitors that serve as the lead molecules to impede the pathway and further affect the survival of the parasite.
