Using the molecular hybridization approach, on the basis of structures of a selective carbonic anhydrase IX inhibitor 3 and an activator of apoptosis 2 (1), a series of 1-substituted isatin-5-sulfonamides 5a–5u were designed and synthesized. The study of the inhibitory activity of isatin-5-sulfonamides showed the ability to inhibit I, II, IX, XII isoforms at nano- and micromolar concentrations. Docking
碳酸酐酶 IX 是寻找具有改进性能的新抗肿瘤化合物的有希望的目标。采用分子杂交方法,基于选择性碳酸酐酶IX抑制剂3和凋亡激活剂2( 1 )的结构,设计并合成了一系列1-取代的靛红-5-磺酰胺5a-5u 。对 isatin-5-sulfonamides 抑制活性的研究表明,它能够在纳摩尔和微摩尔浓度下抑制 I、II、IX、XII 亚型。化合物5e和5k的对接进入 II 和 IX 碳酸酐酶同工型的活性位点显示磺胺阴离子与锌阳离子的配位,以及许多额外的疏水相互作用。三氟甲硫基衍生物5r在低微摩尔浓度下抑制肿瘤细胞的生长,在抗性株系和缺氧条件下保持活性。用5r处理的 MCF7 细胞的免疫印迹显示其抗雌激素活性和激活肿瘤细胞凋亡的能力。
