Inhibitor Comments
Acetazolamide inhibits carbonic anhydrases I, IV and XIV, but has 10-fold lower affinity for XIV.
Methazolamide inhibits carbonic anhydrases I, IV and XIV with similar affinity.
Chlorthalidone is an approved drug inhibitor of carbonic anhydrase activity. We have tagged CA VII and XII as the primary targets for this drug as affinity is highest at these two isozymes [6]. .
