A novel class of ion displacement ligands as antagonists of the αIIbß3 receptor that limit conformational reorganization of the receptor.

A collection of αIIbß3 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.
