Glycyrrhetic acid (2, 3β-hydroxyl-11-oxo-olean-12-ene-29-oic acid), a pentacyclic triterpenoid isolated from Glycyrrhiza glabra, is known to possess a wide range of biological activities. Herein, we report the synthesis and antiproliferative activity of 3-O-ether derivatives of glycyrrhetic acid. The cytotoxicity of the prepared derivatives was investigated in three cancer cell lines, including human
甘草次酸(2,3β-羟基-11-氧代齐墩果-12-烯-29-OIC酸),五环三萜分离自光果甘草,已知具有各种生物活性。在此,我们报道了甘草次酸的3- O-醚衍生物的合成和抗增殖活性。在三种胰腺癌细胞系中研究了制备的衍生物的细胞毒性,包括人类胰腺癌(MIAPaCa-2),前列腺癌(PC-3)和人类肝细胞肝癌(HepG-2)。在测试的化合物中,2,6-二氯苄基5b和2,4-二氯苄基衍生物5r在PC-3细胞中表现出明显的细胞毒性,IC 50分别为6和18μM。二氯苄基衍生物5b在MIAPaCa-2(IC 50:7μM )和HepG-2细胞(IC 50:19μM)中也显示出细胞毒性。此外,通过细胞周期分析,核形态变化和PC-3细胞中的线粒体膜电位损失,研究了化合物5b的凋亡诱导作用。化合物5b导致PC-3细胞中sub-G1种群增加,这表明其具有凋亡特性。有趣的是,化合物5b也阻止了细胞周期的S期。
