A novel class of ion displacement ligands as antagonists of the αIIbβ3 receptor that limit conformational reorganization of the receptor

Bioorg Med Chem Lett. 2014 Feb 15;24(4):1148-53. doi: 10.1016/j.bmcl.2013.12.122. Epub 2014 Jan 8.


A collection of αIIbβ3 integrin receptor antagonists possessing a unique MIDAS metal ion displacement mechanism of action is presented. Insight into these agents' structure-activity relationships, binding modality, and pharmacokinetic and pharmacodynamic profiles highlight the potential of these small molecule ion displacement ligands as attractive candidates for clinical development.

Keywords: Ion displacement ligand; Platelet; αIIbβ3 Integrin receptor.
