CAIX Inhibitor S4

CAIX inhibitor S4 is an inhibitor of carbonic anhydrase IX (CAIX, Ki = 0.007 µM for the recombinant human enzyme). It is selective for CAIX over CAI and CAII but does inhibit CAXII (Kis = 5.6, 0.55, and 0.002 µM, respectively). CAIX inhibitor S4 inhibits proliferation of HT-29 and MDA-MB-231, but not HCT116, cancer cells under anoxic conditions (IC50s = 20, 481, and >1,000 µM, respectively). CAIX inhibitor S4 (10 mg/kg, i.p.) reduces the number of lung metastases, but not primary tumor growth, in an MDA-MB-231 mouse xenograft model.Formal Name: sulfamic acid, 4-[[[(3,5-dimethylphenyl)amino]carbonyl]amino]phenyl ester.
