Tertiary substituted (fluorinated) benzenesulfonamides were synthesized in superacid HF/SbF5 and tested as inhibitors of human carbonic anhydrases (hCAs, EC 4.2.1.1). Strong selectivity toward tumor-associated hCA IX, without inhibiting the offtarget hCA II, was observed, pointing out to a new mechanism of action compared to classical sulfonamides.
在超强酸HF / SbF5中合成了叔取代的(氟化的)苯磺酰胺,并作为人碳酸酐酶的抑制剂进行了测试(hCA,EC 4.2.1.1)。观察到对肿瘤相关hCA IX的强选择性,而不会抑制脱靶hCA II,这表明与经典的磺酰胺类药物相比,它具有新的作用机理。
