Some 2-mercapto-substituted-benzenesulfonamides and their disulfides/sulfones were prepared and investigated as inhibitors of four isoforms of the zinc enzyme carbonic anhydrase (CA, EC 4.2.1.1), that is, CA I and II (cytosolic enzymes), and the tumor-associated CA IX and XII. Some mercaptans led to a consistent increase of inhibitory power (52.8- to 243-fold) over the corresponding oxidized (S-S type)
制备了一些2-巯基取代的苯磺酰胺及其二硫化物/砜,并作为锌酶碳酸酐酶(CA,EC 4.2.1.1)的四种同工型的抑制剂(CA I和II(胞质酶))进行了研究。与肿瘤相关的CA IX和XII。一些硫醇导致抑制能力比相应的氧化(SS型)衍生物稳定增加(52.8-243倍),可作为潜在的缺氧激活药物。
