Activation of the human carbonic anhydrase (CA, EC 4.2.1.1) isozymes I, II (cytosolic) and IX (transmembrane, tumor-associated isoform) with a series of arylsulfonylhydrazido-l-histidines incorporating 4-substituted-phenyl, pentafluorophenyl- and beta-naphthyl moieties was investigated. The compounds showed a weak hCA I activation profile
