were prepared and assayed as inhibitors of cytosolic humancarbonicanhydrase (hCA, EC 4.2.1.1) isoforms hCA I, II and VII. The new compounds showed moderate inhibition of the two ubiquitous isoforms I and II (KIs of 50–390 nM) and excellent inhibitory activity against the brain associated hCAVII (KIs in the range of 4.7–8.5 nM). Isoform VII highly selectiveinhibitors are being detected for the first

A series of aromatic/heterocyclicsulfonamides 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 carbonicanhydrase (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
