Eight rocaglaol derivatives with good cytotoxic activity (IC50: 0.013 ∼ 5.82 μM) were isolated from Aglaia odorata. Then, a series of novel derivatives with modifications on C3 of rocaglaol were designed, synthesized, and screened for their antitumor activities against three tumor cell lines (HEL, MDA-MB-231, and HCT116). A total of 44 derivatives exhibited significant cytotoxic activity with IC50
从Aglaia odorata中分离出八种具有良好细胞毒活性的罗格劳醇衍生物 (IC 50 : 0.013 ∼ 5.82 μM) 。然后,设计、合成了一系列对罗格劳醇 C3 进行修饰的新型衍生物,并筛选了它们对三种肿瘤细胞系(HEL、MDA-MB-231 和 HCT116)的抗肿瘤活性。共有 44 种衍生物表现出显着的细胞毒活性,IC 50值低于 1 μM。特别是,四种衍生物(14、20、22j和22r)对HCT116 细胞表现出最佳的细胞毒活性,IC 50值为 70 nM 。化合物22r选择对正常细胞毒性相对较低且对 HCT116 细胞具有最佳细胞毒活性的药物进行进一步研究。随后的细胞机制研究表明,化合物22r在 HCT116 细胞中诱导细胞凋亡和 G1 细胞周期停滞。此外,化合物22r通过关键蛋白抑制 Wnt/β-catenin 和 MAPK 信号通路,如 p38 和 JNK、GSK-3β、Axin-2
