Abstract:
:Implication of carbonic anhydrases (CAs) in many physiological functions made them attractive therapeutic targets. Herein, we report the synthesis of three series of benzenesulfonamide-based compounds (5a-e, 9a-e and 10a-e) as potential ligands to four of the human CA isoforms (hCA I, hCA II, hCA IX and hCA XII). All synthesized compounds were evaluated for their CA inhibitory activity. Most of the compounds preferentially inhibited the tumor-associated isoforms IX and XII. Series 9a-e and 10a-e showed the highest activity. Of particular interest was compound 10a which demonstrated the highest activity among all compounds with Ki of 68.3 and 21.5 nM against hCA IX and hCA XII, respectively, in addition to its highest selectivity index. To get deep insight on the interaction of compound 10a with CA, docking experiment was run to study the binding interaction with key amino acids and zinc ion in the catalytic site of the four isoforms studied.
