  • We investigated the inhibition of carbonic anhydrase (CA, EC 4.2.1.1) isoforms I-XV with 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenylsulfamide and other simple or sugar sulfamides, a class of less investigated CA inhibitors (CAIs). The cryst ...

    We investigated the inhibition of carbonic anhydrase (CA, EC 4.2.1.1) isoforms I-XV with 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenylsulfamide and other simple or sugar sulfamides, a class of less investigated CA inhibitors (CAIs). The crystal structure of the adduct of hCA II with the boron-substituted sulfamide shows the organic scaffold of this compound bound in the hydrophilic half of the active site where it makes a large number of van der Waals contacts with Ile91, Gln92, Val121, Phe131, Leu198, and Thr200. The data here reported provide further insights into sulfamide binding mechanism confirming that this zinc-binding group could be usefully exploited for obtaining new potent and selective CAIs.
