CAIX Inhibitor S4

CAIX Inhibitor S4 is a potent and selective inhibitor of carbonic anhydrase IX/XII (CA IX/XII), with a K_i of 7 nM and 2 nM, respectively. CAIX Inhibitor S4 also inhibits CA II and CA I (K_i=546 and 5600 nM, respectively). CAIX Inhibitor S4 can inhibit the number of lung metastasis in orthotopic MDA-MB-231 mouse model without affecting primary tumor growth^[1]. IC50 & Target: Ki: 2 nM (CA XII), 7 nM (CA IX), 546 nM (CA II), 5600 nM (CA I)^[1] In Vitro: CAIX Inhibitor S4 (1-100 μM; 24 h) inhibits the proliferation of MDA-MB-231, HCT116 and HT29 cells in a dose-dependent manner^[1].
CAIX Inhibitor S4 (3.3-33 μM; 24 h) inhibits the eGFP-MDA-MB-231 cell migration in anoxia in a concentration- dependent manner^[1].
CAIX Inhibitor S4 (33 μM; 15-60 min) delays the cell spreading of MDA-MB-231 cells in anoxia but essentially not in normoxia^[1]. In Vivo: CAIX Inhibitor S4 (10 mg/kg; i.p. for 14 days) inhibits metastatic tumor burden in MDA-MB-231 model while having no effect on primary tumor growth or mouse condition^[1].
