Human dipeptidyl peptidase iv/cd26 in complex with a 4-aryl cyclohexylalanine inhibitor

Overview

A novel series of 4-arylcyclohexylalanine DPP-4 inhibitors was synthesized, and tested for inhibitory activity as well as selectivity over the related, proline-specific enzymes DPP-8 and DPP-9. Optimization of this series led, to 28 (DPP-4 IC(50)=4.8 nM), which showed an excellent pharmacokinetic, profile across several preclinical species. Evaluation of 28 in an oral, glucose tolerance test demonstrated that this compound effectively reduced, glucose excursion in lean mice.
