compounds were assayed as inhibitors of four human isoforms of the metalloenzyme carbonic anhydrase (hCA, EC 4.2.1.1) involved in various physiological/pathological conditions, hCA I, II, IV and VII. Excellent inhibitory activity was observed against all these isoforms, as follows: hCA I, involved in some eye diseases was inhibited with KIs in the range of 7.3–917 nM; hCA II, an antiglaucoma drug target
通过使用斯陶丁格环加成反应,由磺胺基希夫碱制备了一系列结合有1,3,4-三取代-β-内酰胺基团的苯磺酰胺,并就地获得了乙烯酮。分析了这些新化合物作为涉及多种生理/病理条件hCA I,II,IV和VII的四种金属酶碳酸酐酶人类同工型的抑制剂(hCA,EC 4.2.1.1)。观察到对所有这些同工型均具有优异的抑制活性,如下所示:参与某些眼部疾病的hCA I被K I s抑制在7.3–917 nM之间;hCA II,一种抗青光眼药物靶点,具有K Is在0.76–163 nM的范围内。内酰胺磺酰胺可有效抑制hCA IV(一种涉及多种病理状况(如青光眼,色素性视网膜炎和水肿)的同种型),K I值在0.53–51.0 nM之间,而hCA VII(一种最近被验证的抗神经病变药物)疼痛的目标是通过这些衍生物最抑制同种型,其中K我在0.68-9.1纳米范围内秒。详细讨论了用新型内酰胺-磺酰胺抑制这些CA的构效关系。
