From lead to preclinical candidate: optimization of beta-homophenylalanine based inhibitors of dipeptidyl peptidase IV

Bioorg Med Chem Lett. 2009 Aug 15;19(16):4818-23. doi: 10.1016/j.bmcl.2009.06.036. Epub 2009 Jun 13.

Abstract

A series of highly potent and selective inhibitors of DPP-4 was optimized for ADMET properties. The effort resulted in the discovery of inhibitor 1g, that exhibits excellent efficacy in an oral glucose tolerance test and an attractive pharmacokinetic profile.
