Abstract

Drugs such as necopidem, saripidem, alpidem, zolpidem, and olprinone contain nitrogen-containing bicyclic, condensed-imidazo1,2-alpha]pyridines as bioactive scaffolds. In this work, we report a high-yield one pot synthesis of 1-(2-methyl-8-aryl-substitued-imidazo1,2-alpha]pyridin-3-yl)ethan-1-o nefor the first-time. Subsequently, we performed in silico mode-of-action analysis and predicted that the synthesized imidazopyridines targets Phospholipase A(2) (PLA(2)). In vitro analysis confirmed the predicted target PLA(2) for the novel imidazopyridine derivative1-(2-Methyl-8-naphthalen-1-yl-imidazo1,2-alpha]pyridine-3-y l)-ethanone (compound 3f) showing significant inhibitory activity towards snake venom PLA(2) with an IC50 value of 14.3 mu M. Evidently, the molecular docking analysis suggested that imidazopyridine compound was able to bind to the active site of the PLA(2) with strong affinity, whose affinity values are comparable to nimesulide. Furthermore, we estimated the potential for oral bio-availability by Lipinski's Rule of Five. Hence, it is concluded that the compound 3f could be a lead molecule against snake venom PLA(2).
