The synthesis of a new series of sulfamides incorporating ortho-, meta, and para-benzenesulfamide moieties is reported, which were investigated for the inhibition of two human (h) isoforms of the zinc enzyme carbonic anhydrase (CA, EC 4.2.1.1), hCA I and II, and two Vibrio cholerae enzymes, belonging to the α- and β-CA classes (VchCAα, VchCAβ). The compounds were prepared by using the "tail approach"
据报道,合成了一系列新的结合了邻,间和对苯磺酰胺部分的磺酰胺,并对其抑制锌酶碳酸酐酶的两种人(h)同工型进行了研究(CA,EC 4.2.1.1), hCA I和II,以及两种霍乱弧菌酶,分别属于α-和β-CA类(VchCAα,VchCAβ)。为了克服与属于锌结合剂的CA抑制剂相关的选择性抑制特性的缺乏,通过使用“尾巴法”制备化合物。建立的结构-活性关系表明,苯硫基哌嗪尾部在苯基磺酰胺支架上的掺入确定了对hCA I和VchCAα的相当好的功效,其中几种化合物的KIs <100 nM。对hCA II和VchCAβ的活性较低,可能是由于合并的尾巴非常笨重。获得的证据使我们能够继续研究不同的尾巴/锌结合基团,以提高这种抑制剂对病原体细菌CA的有效性/选择性,从而提供潜在的新型抗感染剂。
