The highly potent and selective dipeptidyl peptidase IV inhibitors bearing a thienopyrimidine scaffold effectively treat type 2 diabetes.

摘要

New dipeptidyl peptidase IV inhibitors were designed based on Alogliptin using a scaffold-hopping strategy. All of the compounds constructed on a thienopyrimidine scaffold demonstrated good inhibition and selectivity for DPP-IV. Compound 10d exhibited subnanomolar (IC(50)=0.33nM) DPP-IV inhibitory activity, good in vivo efficacy and an acceptable pharmacokinetic profile. A pharmacokinetic-driven optimization of 10d may lead to a new class of clinical candidate DPP-IV inhibitors.
