Abstract Design and synthesis of three novel series of aryl enaminones (3a–f and 5a–c) and pyrazole (4a-c) linked compounds with sulphonamides, sulfaguanidine, or carboxylic acid functionalities were reported as carbonic anhydrase inhibitors (CAIs) using the “tail approach” strategy in their design to achieve the most variable amino acids in the middle/outer rims of the hCAs active site. The synthesised
摘要 设计和合成三个新系列的芳基烯胺酮(3a - f和5a - c)和吡唑(4a-c)与磺胺类、磺胺胍或羧酸官能团连接的化合物被报道为碳酸酐酶抑制剂(CAI),使用“尾巴”在他们的设计中采用“方法”策略,以在 hCAs 活性位点的中间/外缘实现最多变的氨基酸。使用停流 CO 2水合酶测定在体外评估合成化合物对以下人 (h) 亚型 hCA I、II、IX 和 XII 的抑制活性。烯胺磺酰胺衍生物 ( 3a – c) 有效抑制靶肿瘤相关亚型 hCA IX 和 hCA XII (KIs 26.2–63.7 nM),因此进一步筛选化合物3a和3c对 MCF-7 和 MDA-MB-231 癌细胞系的体外细胞毒活性常氧和缺氧条件。衍生物3c在含氧量正常((IC 50 = 4.918 和 12.27 µM,分别)和缺氧(IC 50 = 1.689 和 5.898 µM,分别)条件下与含氧量正常(IC
