A series of 4β-[(4-alkyl)-1,2,3-triazol-1-yl] podophyllotoxin derivatives were designed in silico, synthesised by employing click chemistry approach, and evaluated for cytotoxicity against a panel of human cancer cell lines (SF-295, A-549, PC-3, Hep-2, HCT-15 and MCF-7). Majority of the compounds proved to be more potent than etoposide and select compounds exhibited significant anticancer activity
在计算机上设计了一系列4β-[((4-烷基)-1,2,3-三唑-1-基]鬼臼毒素衍生物,通过点击化学方法合成,并评估了其对一组人类癌细胞系的细胞毒性(SF-295,A-549,PC-3,Hep-2,HCT-15和MCF-7)。多数化合物被证明比依托泊苷更有效,某些化合物表现出显着的抗癌活性,IC 50值在0.001–1μM的范围内。DNA片段化和流式细胞仪结果表明,4β-[((4-烷基)-1,2,3-三唑-1-基]鬼臼毒素衍生物诱导剂量依赖性细胞凋亡。对接实验表明,它们与拓扑异构酶-II的相互作用能与观察到的IC 50之间具有良好的相关性 所有这些化合物的值。
