4-tetrahydroquinoline-6-sulfonamide exhibited the strongest inhibitory effect on the proliferation of HeLa (IC50: 1.34 μM), and this value correlated well with the inhibitory activities of the compound against tubulin polymerization (IC50: 6.74 μM). In summary, a new type of quinoline-sulfonamide derivative with tubulin polymerization inhibitory activity was discovered, and it can be used as a lead compound for further
本文合成了一小部分新型喹啉磺酰胺衍生物,并通过1H NMR和MS对其目标化合物的结构进行了确证。采用MTT法筛选了新靶点化合物对肿瘤细胞系的体外细胞毒活性。其中,化合物 D13 (N-(4-methoxybenzyl)-2-oxo-N-(3,4,5-trimethoxyphenyl)-1,2,3,4-tetrahydroquinoline-6-sulfonamide 对HeLa的增殖(IC50:1.34 μM),该值与该化合物对微管蛋白聚合的抑制活性(IC50:6.74 μM)有很好的相关性。综上所述,发现了一种新型的具有微管蛋白聚合抑制活性的喹啉-磺酰胺衍生物, 可作为先导化合物进行进一步改性。
