Molecular modeling, design, synthesis, and biological activity of 1H-pyrrolo[2,3-c]pyridine-7-amine derivatives as potassium-competitive acid blockers

Abstract

A series of 1H-pyrrolo[2,3-c]pyridine-7-amine derivatives were designed and synthesized based on our docking model as potassium-competitive acid blockers (P-CABs). Molecular modeling of these derivatives led us to introduce a substituent at the 1-position to access two lipophilic sites and polar residues. We identified potent P-CABs that exhibit excellent inhibitory activity in vitro and in vivo. These results indicate that the 1H-pyrrolo[2,3-c]pyridine-7-amine derivatives are promising lead compounds as P-CABs.
