Biochem/physiol Actions

S4 is a potent and selective inhibitor against sulfamate carbonic anhydrase (CA) subtypes CAIX & CAXII (Ki = 2, 7, 546, 5600 nM against human CA XII, IX, II, and I, respectively). S4 selectively inhibits migration upon anoxia/hypoxia-induced CAIX expression in cancer cultures (% inhibition/conc./cell line = 54%/100 μM/WRO, 65%/33 μM/MDA-MB-231), while exhibiting no inhibitory effects under normoxia or among non-CAIX-expressing cells (HCT116 & RT112). Daily intraperitoneal injection (10 mg/kg) is reported to reduce the metastatic tumor burden in lungs of mice bearing orthotopic eGFP-MDA-MB-231 tumors in vivo.

A panel of compounds belonging to the underexposed sulfamate class of carbonic anhydrase (CA, EC 4.2.1.1) inhibitors was generated that displayed high specificity at nanomolar levels for the tumor-associated CA IX/XII isoforms. Three of the specific CA IX/XII inhibitors showed

Carbonic anhydrase IX (CAIX) plays a pivotal role in pH homeostasis, which is essential for tumor cell survival. We examined the effect of the CAIX inhibitor 4-(3'(3",5"-dimethylphenyl)-ureido)phenyl sulfamate (S4) on the tumor microenvironment in a laryngeal tumor model by analyzing

A series of 50 sulfamates were obtained by reacting 4-aminophenol with isocyanates followed by sulfamoylation. Most of the new compounds were nanomolar inhibitors of the tumor-associated carbonic anhydrase (CA, EC 4.2.1.1) isoforms IX and XII, whereas they inhibited less cytosolic
