A large number of novel secondary sulfonamides based on the open saccharin scaffold were synthesized and evaluated as selective inhibitors of four different isoforms of human carbonic anhydrase (hCA I, II, IX and XII, EC 4.2.1.1). They were obtained by reductive ring opening of the newly synthesized N-alkylated saccharin derivatives and were shown to be inactive against the two cytosolic off-target
合成了大量基于开放糖精支架的新型仲磺酰胺,并将其评估为人类碳酸酐酶的四种不同同工型的选择性抑制剂(hCA I,II,IX和XII,EC 4.2.1.1)。它们是通过新合成的N-烷基化糖精衍生物的还原性开环获得的,并且显示出对两种胞质脱靶hCA I和II(Kis> 10 µM)无活性。有趣的是,这些化合物在低纳摩尔范围内抑制hCA IX,Kis在20至298 nM之间,并且是hCA XII同工酶的极强抑制剂(Kis在4.3至432 nM之间)。由于hCA IX和XII是最近被证实可作为药物靶标的与癌症相关的亚型,因此这些结果代表了开发新的抗癌候选药物的重要目标。最后,
