We report two series of novel benzenesulfonamide derivatives acting as effective carbonic anhydrase (CA, EC 4.2.1.1) inhibitors. The synthesized compounds were tested against human (h) isoforms hCA I, hCA II, hCA VII, and hCA XII. The first series of compounds, 4-(3-(2-(4-substitued piperazin-1-yl)ethyl)ureido)benzenesulfonamides, showed low nanomolar inhibitory action against hCA II, being less effective
我们报告了两个系列的新型苯磺酰胺衍生物,可作为有效的碳酸酐酶(CA,EC 4.2.1.1)抑制剂。测试了合成的化合物对人(h)同工型hCA I,hCA II,hCA VII和hCA XII的抵抗力。第一组化合物4-(3-(2-(4-取代的哌嗪-1-基)乙基)脲基)苯磺酰胺显示出对hCA II的低纳摩尔抑制作用,对其他同种型的效力较低。第二系列2-(4-取代的哌嗪-1-基)-N-(4-氨磺酰基苯基)乙酰胺衍生物对hCA II和hCA VII(参与癫痫发生的同种型)显示出较低的纳摩尔抑制活性。对其中一些衍生物的抗惊厥活性进行了评估,并对瑞士白化病小鼠的MES和scPTZ诱导的癫痫发作表现出有效的癫痫发作保护作用。还发现这些磺酰胺在向Wistar大鼠口服给药时有效,并且在该疾病的动物模型中抑制了MES诱导的癫痫发作。在进行的时程抗惊厥研究中,一些新化合物显示出长效作用,在亚急性毒性研究中无毒。
