Inhibitor Comments
Methazolamide inhibits carbonic anhydrases I, IV and XIV with similar affinity.
Acetazolamide inhibits carbonic anhydrases I, IV and XIV but has 10-fold lower affinity at XIV.
Diclofenamide inhibits carbonic anhydrases I and IV.
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 [9].
