A series of aromatic/heterocyclic sulfonamides incorporating phenyl(alkyl), halogenosubstituted-phenyl- or 1,3,4-thiadiazole-sulfonamide moieties and thienylacetamido; phenacetamido and pyridinylacetamido tails were prepared and assayed as inhibitors of four physiologically relevant carbonic anhydrase (CA, EC 4.2.1.1) isoforms, the cytosolic human (h) hCA I and hCA II, and the mitochondrial hCA VA
一系列芳族/杂环磺酰胺,结合有苯基(烷基),卤代-苯基或1,3,4-噻二唑-磺酰胺基团和噻吩基乙酰胺基;制备了苯乙酰胺和吡啶基乙酰胺尾巴,并作为四种生理相关的碳酸酐酶(CA,EC 4.2.1.1)同工型,胞质人(h)hCA I和hCA II以及线粒体hCA VA和hCA VB的抑制剂进行了分析。新化合物显示出对两种胞浆同工型的中等抑制作用(K I为50–390 nM),对两种线粒体酶具有优异的抑制活性,并且检测到许多低纳摩尔抑制剂(K Is的范围为5.9-10.2 nM。此处探讨的所有取代模式均会产生有效的hCA VA / VB抑制剂。还检测到一些hCA VA / VB选择性抑制剂,其抑制线粒体的选择性比胞质同工酶的选择性大约为55.5-56.9。由于hCA VA / VB参与了丙酮酸羧化酶,乙酰基CoA羧化酶和氨基甲酰磷酸合成酶I和II催化的几种生物合成过程,为这些参与脂肪酸生物合成的羧
