condensation of sulfanilamide with substituted aromatic aldehydes. The Schiff bases were thereafter reduced with sodium borohydride, leading to the corresponding amines, derivatives of 4-sulfamoylphenyl-benzylamine. These sulfonamides were investigated as inhibitors of the human carbonic anhydrase (hCA, EC 4.2.1.1) isoforms hCA I and II (cytosolic isozymes), as well as hCA IX and XII (transmembrane, tumor-associated
通过磺胺与取代的芳族醛缩合获得亚胺衍生物。然后用硼氢化钠还原席夫碱,得到相应的胺,即4-氨磺酰基苯基-苄胺的衍生物。研究了这些磺酰胺作为人碳酸酐酶(hCA,EC 4.2.1.1)同工型hCA I和II(胞质同工酶)以及hCA IX和XII(跨膜,肿瘤相关酶)的抑制剂。我们注意到,与相应的席夫碱相比,掺有仲胺部分的化合物对所有CA同工酶表现出更好的抑制活性。检测到低纳摩尔CA II,IX和XII抑制剂,而针对hCA I的活性较低。结合了磺酰胺或类似锌结合基团的仲胺,
