(OA)-linked disulfide, thioether, or selenium ether derivatives was synthesized, and their antiproliferative activity was evaluated against human liver cancer (BEL-7402 and HepG-2), colon cancer (HCT116), and normal liver (L02) cell lines using methyl thiazolyl tetrazolium assay (MTT). Preliminary bioassay results revealed that OA derivatives modified at the C3−OH position, i. e., compound a4 containing
合成了一系列新型齐墩果酸(OA)连接的二硫化物、硫醚或硒醚衍生物,并评估了它们对人肝癌(BEL-7402和HepG-2)、结肠癌(HCT116)和正常人的抗增殖活性。使用甲基噻唑基四唑测定法 (MTT) 的肝 (L02) 细胞系。初步的生物测定结果表明,OA衍生物在 C3-OH 位置进行了修饰,即。例如,含有硫化醚的化合物a4对BEL-7402细胞表现出最好的抗增殖活性,IC 50值为5.70±0.82 μM。进一步的流式细胞术分析表明,化合物a4通过诱导细胞周期停滞在 G2/M 期导致细胞凋亡来发挥其抗增殖作用。此外,与先导化合物OA和阳性对照药物 5-氟尿嘧啶 (5-FU) 相比,OA衍生物对癌细胞系表现出有效的抗增殖活性。
