We report aryl sulfonamide inhibitors of human carbonic anhydrase (hCA; EC 4.2.1.1) enzymes containing short ureido alkoxy tails. The inhibition potency of such compounds was investigated in vitro on the major hCA isoforms (i.e. I, II, IX, and XII). A selection of the most potent inhibitory derivatives against the hCA IX isoform (i.e. 5a, 5c, and 6c) was studied, and their binding modes on either hCA II and IX-mimic isoform were assessed by X-ray crystallography on the corresponding ligand/protein adducts. This study adds to the field of developing hCA inhibitors at molecular level the critical interactions governing ligand selectivity.

Abstract
We report aryl sulfonamide inhibitors of human carbonic anhydrase (hCA; EC 4.2.1.1) enzymes containing short ureido alkoxy tails. The inhibition potency of such compounds was investigated in vitro on the major hCA isoforms (i.e. I, II, IX, and XII). A selection of the most potent inhibitory derivatives against the hCA IX isoform (i.e. 5a, 5c, and 6c) was studied, and their binding modes on either hCA II and IX-mimic isoform were assessed by X-ray crystallography on the corresponding ligand/protein adducts. This study adds to the field of developing hCA inhibitors at molecular level the critical interactions governing ligand selectivity.
