studies to optimise potent carbonic anhydrase inhibitors, two new series of isatin N-phenylacetamide based sulphonamides were synthesised and screened for their human (h) carbonic anhydrase (EC 4.2.1.1) inhibitory activities against four isoforms hCA I, hCA II, hCA IX and hCA XII. The indole-2,3-dione derivative 2h showed the most effective inhibition profile against hCAI and hCA II (KI = 45.10, 5.87 nM)
摘要 继续我们之前优化强效碳酸酐酶抑制剂的研究,合成了两个新系列的基于靛红N-苯乙酰胺的磺胺类药物,并筛选了它们对人 (h) 碳酸酐酶 (EC 4.2.1.1) 对四种异构体h CA I 的抑制活性, h CA II、h CA IX 和h CA XII。与作为标准抑制剂的乙酰唑胺 ( AAZ)相比,吲哚-2,3-二酮衍生物2h对h CAI 和h CA II (K I = 45.10, 5.87 nM)显示出最有效的抑制曲线。此外,2h对肿瘤相关的h CA XII 显示出明显的抑制活性,类似于AAZ,分别显示 7.91 和 5.70 nM 的K I。类似物3c和3d显示出良好的细胞毒性作用,并且3c显示出对肺细胞系 A549 的有希望的选择性。进行分子对接2h和3c以预测它们对h CA I、II、IX 和 XII 同种型的结合构象和亲和力。
