Structure-activity relationship of a series of non peptidic RGD integrin antagonists targeting α5β1: part 2

Bioorg Med Chem Lett. 2012 Jun 15;22(12):4117-21. doi: 10.1016/j.bmcl.2012.04.061. Epub 2012 Apr 21.

Abstract

Potent antagonists of the integrin α(5)β(1), which are RGD mimetics built from tyrosine are described. This paper describes the optimization of in vitro potency obtained by variation of two parts of the molecule, the central aromatic core and the amide moiety.
