Human dipeptidyl peptidase IV/CD26 in complex with a cyclohexalamine inhibitor
Overview
Molecular modeling was used to design a rigid analog of sitagliptin 1. The, X-ray crystal structure of sitagliptin bound to DPP-4 suggested that the, central beta-amino butyl amide moiety could be replaced with a, cyclohexylamine group. This was confirmed by structural analysis and the, resulting analog 2a was synthesized and found to be a potent DPP-4, inhibitor (IC(50)=21nM) with excellent in vivo activity and, pharmacokinetic profile.
