Abstract
Prodrugs are prepared of the carbonic anhydrase inhibitors 2-benzothiazolesulfonamide, hydroxymethazolamide, and dichlorphenamide. The prodrugs link a water soluble compound to the pharmacologically active carbonic anhydrase inhibitor through an enzymatically or hydrolytically degradable bond.
