Study of AMP-Activated Protein Kinase Agonists by Structure-Based Drug Designing

Abstract

AMP-activated protein kinase (AMPK) is a metabolite- sensed protein kinase in various eukaryotes. The activated AMPK regulates important proteins which cause diabetes, obesity, metabolic aberrant, and also breast cancer. In this study, the yeast AMPK structure was used as a template to model the human AMPK structure. By homology modeling, the reliable AMPK structure was built, and the active binding site was defined corresponding to X-ray crystal structure of yeast AMPK By virtual screening the database., All the potent ligands had the H-bond interaction in the key residues, same as the control. Thus, we suggested the phenylamide derivates might be the potent AMPK agonists.
