    Abstract

    The RGD integrins are recognized therapeutic targets for thrombosis, fibrosis, and cancer, amongst others. Current inhibitors are designed to mimic the tripeptide sequence (arginineglycine-aspartic acid) of the natural ligands; however, the RGD-mimetic antagonists for αIIbβ3 have been shown to cause partial agonism, leading to the opposite pharmacological effect. The challenge of obtaining oral activity and synthetic tractability with RGD-mimetic molecules, along with the issues relating to pharmacology, has left integrin-therapeutics in need of a new strategy. Recently, a new generation of inhibitor has emerged that lacks the RGD-mimetic. This 2 perspective will discuss the discovery of these non-RGD-mimetic inhibitors, and the progress that has been made in this promising new chemotype.
