We discovered novel and selective sulfonamides/amides acting as inhibitors of the a-carbonic anhydrase
(CA, EC 4.2.1.1) from the pathogenic bacterium Vibrio cholerae (VchCA). This Gram-negative bacterium is
the causative agent of cholera and colonises the upper small intestine where sodium bicarbonate is present
at a high concentration. The secondary sulfonamides and amides investigated here were potent, low
nanomolar VchCA inhibitors whereas their inhibition of the human cytosolic isoforms CA I and II was in
the micromolar range or higher. The molecules represent an interesting lead for antibacterial agents with
a possibly new mechanism of action, although their CA inhibition mechanism is unknown for the moment.
