Discovery of new binding elements in DPP-4 inhibition and their applications in novel DPP-4 inhibitor design

Bioorg Med Chem Lett. 2008 Jul 1;18(13):3706-10. doi: 10.1016/j.bmcl.2008.05.061. Epub 2008 May 20.

Abstract

Probing with tool molecules, and by modeling and X-ray crystallography the binding modes of two structurally distinct series of DPP-4 inhibitors led to the discovery of a rare aromatic fluorine H-bond and the spatial requirement for better biaryl binding in the DPP-4 enzyme active site. These newly found binding elements were successfully incorporated into novel DPP-4 inhibitors.
