摘要
目的 设计合成几种含硫(硒)醚键的羟喜树碱衍生物,并进行体外抗肿瘤活性筛选。方法 以天然产物羟喜树碱为起始原料,通过引入硫醚、硒醚及二硫醚键合成得到9个两亲性羟喜树碱衍生物。采用MTT法测试目标化合物对于人正常的肝细胞(L02)、肝癌细胞(HepG2)和人肺癌细胞(A549)的体外细胞毒性。结果与结论目标化合物均未见文献报道,其结构经H-NMR、^(13)C-NMR、HR-MS谱表征得以确证。其中含有硫醚及二硫醚键的羟喜树碱衍生物对L02细胞毒性显著降低,而对肿瘤细胞更具针对性。
A series of amphiphilic hydroxy-camptothecin derivatives containing sulfide, selenide and disulfide bonds were synthesized and their antitumor activities in vitro were evaluated.By a facile synthetic route, nine novel hydroxycamptothecin derivatives were obtained and their structures were confirmed by ~1H-NMR,C-NMR and HR-MS.The cytotoxicities of the target compound to human normal hepatocytes(L02),liver cancer cells(HepG2) and human lung cancer cells(A549) in vitro were tested by MTT method.The results show that the hydroxycamptothecin derivatives containing sulfide disulfide bond significantly reduce the toxicity toward L02 while remaining its toxicity toward tumor cells.
