In this work, we present the synthesis and biological evaluation of novel series of diamide-based benzenesulfonamides 5a–h as inhibitors of the metalloenzyme carbonic anhydrase (CA, EC 4.2.1.1) isoforms hCA I, II, IX and XII. The target tumor-associated isoforms hCA IX and XII were undeniably the most affected ones (KIs: 8.3–123.3 and 9.8–134.5 nM, respectively). Notably, diamides 5a and 5h stood out
在这项工作中,我们介绍了作为金属酶碳酸酐酶(CA,EC 4.2.1.1)同工型hCA I,II,IX和XII抑制剂的新型基于二酰胺的苯磺酰胺5a–h系列的合成和生物学评估。不可否认,与靶标肿瘤相关的同工型hCA IX和XII是受影响最严重的同工型(KIs:分别为8.3–123.3和9.8–134.5 nM)。值得注意的是,二酰胺5a和5h以一位数的纳摩尔hCA IX抑制剂(KIs = 8.8和8.3 nM)脱颖而出。SAR结果表明,用化合物2h的杂2-呋喃基部分对亚苄基化合物5a-g进行生物等位取代,实现了最佳的IX / I和IX / II选择性,SI分别为985和13.8。在CA IX活性位点内制备的二酰胺的分子对接模拟显示5h在杂环氧和HE / Gln67之间建立额外的H键的能力。此外,评价了苯磺酰胺5a,5b和5h对肾癌UO-31细胞系的抗肿瘤活性。化合物5h是最有效的衍生物,其增强活性(IC50
