  Carbonic Anhydrase Inhibitors:  Inhibition of Isozymes I, II, and IX with Triazole-Linked O-Glycosides of Benzene Sulfonamides

  摘要：

  We report the synthesis of a series of benzene sulfonamides containing triazole-O-glycoside tails for evaluation as carbonic anhydrase (CA) inhibitors. These glycoconjugates were synthesized by the 1,3-dipolar cycloaddition reaction of 4-azidobenzenesulfonamide with O-propynyl glycosides. Compounds were assessed for their ability to inhibit the enzymatic activity of the physiologically dominant isozymes hCA I and II and the tumor-associated isozyme hCA IX (h = human). Against hCA I these compounds were either micromolar or low-nanomolar inhibitors, while against hCA II and IX inhibition in the range of 6.8-53 and 9.7-107 nM, respectively, was observed. The most potent inhibitor against hCA IX was the galactose derivative 8 (K-i = 9.7 nM); this is so far the most potent glycoconjugate inhibitor reported for the tumor-associated hCA IX. These carbohydrate-tethered sulfonamides may prove interesting lead candidates to target tumor-associated CA isozymes, wherein the CA domain is located extracellularly.
