moieties on the cytotoxicity of podophyllotoxin derivatives, novel 4- N - and 4- C -substituted 4′- O -demethylepipodophyllotoxin derivatives were designed and synthesized. All the compounds were tested against A549 and MCF-7 tumor cells in vitro , and six compounds showed significant cytotoxicity. The most active compound 9f was superior to GL-331, and exhibited potent cytotoxicity with IC 50 value
摘要为了研究不同的C4键部分对鬼臼毒素衍生物的细胞毒性的影响,设计合成了4-N-和4-C-取代的4'-O-去甲基表鬼臼毒素衍生物。所有化合物均在体外针对A549和MCF-7肿瘤细胞进行了测试,其中六种化合物显示出显着的细胞毒性。活性最高的化合物9f优于GL-331,并具有较强的细胞毒性,IC 50值为10 -7 mol / L。
