Emergence of Small-Molecule Non-RGD-Mimetic Inhibitors for RGD Integrins: Miniperspective
Open accessAbstract
The RGD integrins are recognized therapeutic targets for thrombosis, fibrosis, and cancer, among others. Current inhibitors are designed to mimic the tripeptide sequence (arginine–glycine–aspartic acid) of the natural ligands; however, the RGD-mimetic antagonists for α IIb β 3 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 review will discuss the discovery of these non-RGD-mimetic inhibitors and the progress that has been made in this promising new chemotype.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
