A series of glycyrrhetinic acid, oleanolic acid and ursolic acid derivatives were designed and synthesized. Structures of all novel compounds were determined by 1H NMR, 13C NMR, and HRMS methods. In vitro anti-proliferative effects of all compounds were evaluated against A549, Hela and HepG2 cancer cell lines. The three compounds G2, G3 and G4 showed better anti-proliferative effects than the positive
设计合成了一系列
甘草次酸、

生物。所有新化合物的结构均通过1 H NMR、13 C NMR 和 HRMS 方法确定。评估了所有化合物对 A549、Hela 和 HepG2 癌
细胞系的体外抗增殖作用。三种化合物G2、G3和G4对三种癌细胞显示出比阳性对照
阿霉素更好的抗增殖作用。两种化合物O1和U11对Hela细胞显示出比
阿霉素更好的抗增殖作用。四种化合物O2 , O3 , O8和U8表现出比对HepG2细胞
阿霉素更好的抗增殖作用。值得注意的是,化合物G3对 Hela 和 HepG2 细胞的生长抑制作用最强,IC 50值分别为 0.16 ± 0.23 µM 和 0.33 ± 0.41 µM,化合物G2的生长抑制作用最强,IC 50值为 0.80 ± 1.03 µM在 A549 细胞上。
