GtoPdb Ligand ID: 10495

Synonyms: CWHM 12 | CWHM-12
Compound class: Synthetic organic
Comment: CWHM12 is a pan αv integrin antagonist [1]. It was used to determine that αv integrin activation regulates fibrosis in models of organ fibrosis. These findings suggest that targeting all αv integrins may have clinical utility in the treatment of a broad range of fibrotic diseases. The S enantiomer of CWHM12 is the bioactive form; the R enantiomer does not inhibit any of the five αv-containing integrins in vitro.
Structurally, CWHM12 is a small-molecule RGD peptidomimetic antagonist in which the arginine (R) mimetic is a cyclic guanidino-substituted phenyl group and the aspartic acid (D) mimetic is a phenyl-substituted β amino acid. These two residues are linked by a glycine (G).

Bioactivity Comments
CWHM12 does not bind to non-αv integrins in in vitro ligand-binding assays [1]. Binding to αvβ5 (IC50 61 nM) is slightly less potent than binding to the other αv integrins (IC50 0.2-1.8 nM).
