of tryptamine salicylic acid derivatives were synthesized and their antiproliferative activity against MGC-803, MCF-7, HepG2, A549 and HeLa cell lines was evaluated. The structure-activity relationship (SAR) study revealed that different substitutions of the C5 and C3'-C5' positions have certain effects on the anti-proliferation activity. The growth assay revealed that N-[2-(5-bromo-1H-indol-3-yl)-e
合成了一系列色胺水杨酸衍生物,并评估了它们对 MGC-803、MCF-7、HepG2、A549 和 HeLa 细胞系的抗增殖活性。构效关系(SAR)研究表明,C5和C3'-C5'位置的不同取代对其抗增殖活性有一定影响。生长测定表明,N-[2-(5-bromo-1H-indol-3-yl)-乙基]-2-羟基-3-甲基-苯甲酰胺 (E20) 显示出最有效、最广谱的抗癌抑制作用对所有细胞系进行了评估,结果仅比 5-Fu 对胃癌细胞系更有效。初步研究表明,化合物E20可以抑制MGC-803细胞的集落形成和迁移。流式细胞术(FCM)结果显示,化合物E20将细胞周期阻滞在G2/M期,并以浓度依赖性方式诱导MGC-803细胞凋亡。此外,蛋白质印迹结果显示E20可以下调己糖激酶2的表达。我们的研究表明N-[2-(5-bromo-1H-indol-3-yl)-乙基]-2的框架-羟基-3-甲基-苯甲酰胺可能被
