Reaction of perfluoroalkyl/arylsulfonyl chlorides or perfluoroalkyl/arylcarbonyl chlorides with aromatic/heterocyclic sulfonamides possessing a free amino/imino/hydrazino/hydroxy group afforded compounds with the general formula C(x)()F(y)()Z-A-SO(2)NH(2), where Z = SO(2)NH, SO(3), CONH, or CO(2) and A = aromatic/heterocyclic moiety. The sulfonyl chlorides used in synthesis included: CF(3)SO(2)Cl,
全氟烷基/芳基磺酰氯或全氟烷基/芳基羰基氯与具有游离氨基/亚氨基/肼基/羟基的芳族/杂环磺酰胺反应,得到通式C(x)()F(y)()ZA-SO(2)的化合物NH(2),其中Z = SO(2)NH,SO(3),CONH或CO(2),A =芳香族/杂环部分。合成中使用的磺酰氯包括:CF(3)SO(2)Cl,nC(4)F(9)SO(2)Cl,nC(8)F(17)SO(2)Cl和C(6 )F(5)SO(2)Cl,而酰氯为C(8)F(17)COCl和C(6)F(5)COCl。借助于上述全氟磺酰基/酰基卤,总共衍生了25种不同的磺酰胺。这些新的磺酰胺系列对碳酸酐酶(CA)的同工酶I,II和IV具有很强的亲和力。对于通过上述程序衍生的给定磺酰胺,与相应的全氟烷基/芳基羰基化化合物相比,烷基/芳基磺酰化化合物的抑制力更大。体外抑制活性通常随着酰化/磺酰化剂分子中碳原子数的增加而增加,全氟苯基磺酰化和全氟苯
