SRI 31215 (TFA) is a Matriptase/Hepsin/hepatocyte growth factor activator (HGFA) triplex inhibitor and mimics the activity of HAI-1/2 (endogenous inhibitors of HGF activation). SRI 31215 has potent inhibitory activity against matriptase, hepsin and HGFA with IC50 values of 0.69 μM, 0.65 μM and 0.30 μM, respectively. SRI 31215 can be used for the research of cancer[1]
