series of sulfonamides was obtained by reacting substituted-2-(1,3-dioxo-1,3-dihydroisobenzofuran-5-carboxamido)benzoic acids with aromatic sulfonamides incorporating primary amino moieties. The new compounds were investigated as inhibitor of four carbonic anhydrase (CA, EC 4.2.1.1) isoforms, the human (h) hCA I and II, and the α- and β-class CAs from the pathogenic bacterium Vibrio cholerae, VchCAα
通过使取代的-2-(1,3-二氧代-1,3-二氢异苯并呋喃-5-羧酰胺基)苯甲酸与并入伯氨基部分的芳族磺酰胺反应,可获得一系列磺酰胺。研究了这些新化合物作为四种碳酸酐酶(CA,EC 4.2.1.1)异构体,人(h)hCA I和II以及致病性霍乱弧菌,VchCAα和VhcCAβ的α-和β-类CA的抑制剂。 。hCA I被新的磺胺类药物有效抑制,抑制常数在4.9-96.0nM范围内。hCA II对这些化合物也显示出高亲和力(KIs为2.1-22.3nM),而对两种细菌酶的抑制作用较弱,对VchCAα的KIs为281-3192nM,对VhcCAβ的KIs为5.40-9.26µM。由于对hCA I的生理功能知之甚少,
