series of sulfocoumarin-, coumarin-, and 4-sulfamoylphenyl-bearing indazole-3-carboxamide hybrids were synthesized and investigated as inhibitors of human carbonic anhydrase (hCA, EC 4.2.1.1) isoforms I, II, IX, and XII. Most of these compounds displayed excellent potency and selectivity against hCA isoforms IX and XII, which have been recently validated as antitumor drug targets.
