A series of aromatic and heterocyclic sulfonamides incorporating R- and S-camphorsulfonyl moieties were synthesized and investigated for the inhibition of several mammalian isoforms of the zinc enzyme carbonic anhydrase (CA, EC 4.2.1.1). The new sulfonamides selectively inhibited the mitochondrial isozymes hCA VA and VB (h = human isoform) over the cytosolic, off-target ones hCA I and II, with inhibition
合成了一系列结合有R-和S-樟脑磺酰基部分的芳香族和杂环磺酰胺,并研究了它们对锌酶碳酸酐酶的几种哺乳动物同工型的抑制作用(CA,EC 4.2.1.1)。新的磺酰胺类药物选择性抑制线粒体同工酶hCA VA和VB(h =人同工型),超过了细胞质的脱靶hCA I和II,抑制常数在低纳摩尔范围内。取代磺酰胺支架的基团的手性和位置极大地影响了CA的抑制性能。这些化合物是设计针对参与脂肪形成和肥胖症的线粒体CA的同工型选择性酶抑制剂的极好线索。
