results obtained showed that compounds 5h, 5i, and 5n exhibited significant cytotoxic activities against the six cell lines, being more potent than their parent compound sarsasapogenin. Furthermore, the p-fluorobenzyloxy series of compounds generally exhibited stronger cytotoxicities against all the tested cancer cells compared with the benzyloxy and p-methoxybenzyloxy series, and the substitution of pyrrolidinyl
基于一种事实,即从知母七倍体的根茎中分离出的皂苷Timosaponin A-III是治疗癌症的有前途的生物活性先导化合物,sarsasapogenin C3和C26位置的结构修饰一直是我们结构的重点活动调查。在本文中,我们描述了一系列新衍生物5a-5o的合成以及在体外使用MTT分析在一组六种人类癌细胞系中评估其抗肿瘤活性。获得的结果表明化合物5h,5i和5n对六种细胞系表现出显着的细胞毒活性,比其母体化合物sarsasapogenin更有效。此外,与苄氧基和对甲氧基苄氧基系列相比,对氟苄氧基系列化合物通常对所有测试癌细胞表现出更强的细胞毒性,并且在C26位取代吡咯烷基和哌嗪基是这些化合物展示的优选选择。抗肿瘤活性。化合物5N表现出优异的细胞毒性活性对MCF-7细胞系(IC 50 = 2.95 μ M),和为16.7倍菝葜皂苷元更有效。5n细胞机制的进一步研究结果表明,它在G2 / M期
