Taking sophoridine as a lead compound, 58 sophoridine derivatives were designed, synthesized and evaluated for their antiproliferative activity in the HepG2 cancer cell line. Among the 58 compounds, 33 compounds showed potent antiproliferative activity with IC50 less than 10 μM. Compound 5w showed the most potent anti-proliferative activity in the HepG2 cancer cell line. Thus, we further extended our
以槐定碱为先导化合物,设计,合成并评价了58种槐定碱衍生物在HepG2癌细胞系中的抗增殖活性。在58种化合物中,有33种化合物显示出有效的抗增殖活性,IC 50小于10μM。化合物5w在HepG2癌细胞系中显示出最有效的抗增殖活性。因此,我们进一步扩展了在6种癌细胞系(HepG2,SMMC-7721,Hela,CNE1,CNE2和MCF7)中5w的抗增殖活性的表征。代表性化合物5w在所有测试的具有IC 50的细胞系中均显示出强大的抗增殖活性值在0.93-1.89μM之间,远低于槐定啶。在这里,我们报道了槐定碱系列化合物的构效关系(SAR),这表明在槐定啶的14个碳原子上引入N-苄基吲哚基团可以显着增强抗增殖活性。通过分子对接和酶促测定,发现化合物5w能够抑制DNA Topo I的活性。此外,凋亡测定表明,化合物5w通过激活caspase-3可以剂量依赖性显着诱导HepG2细胞凋亡。 ,增加
