Abstract A series of 20 newly designed (E)-1-(4-sulphamoylphenylethyl)-3-arylidene-5-aryl-1H-pyrrol-2(3H)-ones was synthesised and assessed as carbonic anhydrase (CA, EC 4.2.1.1) inhibitors towards four human isoforms of pharmaceutical interest, that is, hCA I, II, IX and XII. The compounds displayed low to high nanomolar potency against all the isoforms. Introducing strong electron withdrawing groups
摘要 合成了一系列 20 种新设计的 ( E )-1-(4-sulphamylphenylethyl)-3-arylidene-5-aryl-1H-pyrrol-2(3H)-ones 并评估为碳酸酐酶 (CA, EC 4.2.1.1 ) 四种具有药学意义的人类亚型的抑制剂,即 hCA I、II、IX 和 XII。这些化合物对所有亚型都显示出低到高的纳摩尔效力。在亚芳基环的对位引入强吸电子基团增加了与酶的结合亲和力。所有化合物都显示出可接受的药代动力学范围和理化特性,如通过计算 ADMET 分析所确定的。进行了3n的密度泛函理论 (DFT) 计算,以了解E和Z异构体。能量值清楚地表明E异构体相对于Z异构体的稳定性为 -8.2 kJ mol -1。我们的研究结果表明,这些分子可用作发现新 CA 抑制剂的线索。
