We report the synthesis and the pharmacological evaluation of a new class of human carbonic anhydrase (hCA) inhibitors prepared regio- and stereoselectively by reacting sulfanilamide with ethyl trans-phenylglycidate in the presence of cobalt(II) chloride. Various derivatizations of the ester moiety in the parent compound led to a small library of derivatives (2R,3R and 2S,3S) which displayed interesting inhibitory activities towards the human tumor-associated isoform CA IX. One of the new compounds shows high selectivity in inhibiting hCA IX compared to the two physiologically relevant, cytosolic isozymes hCA I and hCA II. A molecular modeling study was conducted in order to simulate the binding mode of this new family of enzyme inhibitors within the active sites of hCA IX and hCA II.
