more effective antitumor steroidal drugs, we synthesized a library including twenty-two novel cytotoxic 2-alkyloxyl substituted (25R)-spirostan-1,4,6-triene-3-ones and corresponding 1,2,3-triazoles through an abnormal monoepoxide ring-opening/elimination and ‘click’ reactions. After the cytotoxic evaluations against HepG2, Caski and HeLa cell lines, three steroidal triazoles 5b, 5f and 5m in this library
为了开发更有效的抗肿瘤甾体药物,我们合成了一个文库,该文库通过以下方法合成了一个库,该库包括二十二种新的细胞毒性的2-烷氧基取代的(25 R)-spirostan-1,4,6-三烯-3-酮和相应的1,2,3-三唑异常的单环开环/消除和“喀哒”反应。在对HepG2,Caski和HeLa细胞系进行细胞毒性评估后,发现该文库中的三种甾体三唑5b,5f和5m具有对Caski细胞的强抗增殖作用,其半抑制浓度(IC 50)为9.4-11.8。微米 高效,简单的方法是轻松制备抗肿瘤甾体三唑的诱人之处。
