Development of potent carbonic anhydrase inhibitors incorporating both sulfonamide and sulfamide groups.

A series of compounds incorporating both sulfonamide and sulfamide as zinc-binding groups (ZBGs) are reported as inhibitors of the metalloenzyme carbonic anhydrase (CA, EC 4.2.1.

Sulfonamides incorporating boroxazolidone moieties are potent inhibitors of the transmembrane, tumor-associated carbonic anhydrase isoforms IX and XII.

A new series of sulfonamides was synthesized by the reaction of the boroxazolidone complex of l-lysine with isothiocyanates incorporating sulfamoyl moieties and diverse organic scaffolds. The obtained thioureas have been investigated as inhibitors of four physiologically relevant human carbonic anhydrase (hCA, EC 4.2.
