Discovery of beta-homophenylalanine based pyrrolidin-2-ylmethyl amides and sulfonamides as highly potent and selective inhibitors of dipeptidyl peptidase IV

Bioorg Med Chem Lett. 2009 Aug 1;19(15):4201-3. doi: 10.1016/j.bmcl.2009.05.109. Epub 2009 May 30.

Abstract

Modifications of DPP-4 inhibitor 5, that was discovered by structure based design, are described and structure-activity relationships discussed. With analogue 7k one of the most potent non-covalent inhibitors of DPP-4 reported to date (IC(50)=0.38nM) was discovered. X-ray structure of inhibitor 7k bound to DPP-4 revealed a hydrogen bonding interaction with Q553. First successful efforts in balancing overall properties, as demonstrated by improved metabolic stability, highlight the potential of this series.
