We report the design, synthesis and pharmacological assessment of novel benzenesulfonamide derivatives acting as effective carbonic anhydrase (CA, EC 4.2.1.1) inhibitors. All the synthesized compounds were screened for their CA inhibitory action against four isoforms of human origin (h), i.e. hCA I, hCA II, hCA VII and hCA IX. In-vitro carbonic anhydrase inhibition studies have shown that first series
我们报告新型苯磺酰胺衍生物作为有效的碳酸酐酶(CA,EC 4.2.1.1)抑制剂的设计,合成和药理学评估。筛选所有合成的化合物对人类起源的四种同工型(h),即hCA I,hCA II,hCA VII和hCA IX的CA抑制作用。体外碳酸酐酶抑制研究表明,第一个系列的4-(2-(4-(4-(4-取代的哌嗪-1-基)亚苄基)肼基)苯磺酰胺(4a-4i)使低纳摩尔范围的分子对中等纳摩尔范围的抑制剂具有抗hCA II和hCA VII有效参与了癫痫发生。此外,属于第二系列的化合物4-(2-(4-(4-取代的哌嗪基)亚苄基)肼基羰基)苯磺酰胺(8a-8k)对hCA VII表现出有效的抑制作用,对其他hCA亚型的抑制作用较弱。借助获得的CA抑制结果,我们选择了一些有效的hCA II和hCA VII抑制剂(4g,4i和8d)来测试其在瑞士白化病雄性小鼠中对MES和sc-PTZ癫痫发作试验的抗惊厥功效。结果
