Abstact

A series of hydroxybenzoic acid derivatives have shown inhibitory activity against carbonic anhydrase (CA). X-ray crystallography shows that these molecules inhibit not by binding the active site metal ion but by strong hydrogen bonding to the metal-bound water nucleophile. The binding mode observed for these molecules is distinct when compared to other non-metal-binding CA inhibitors.
