Based on the mechanism of action, novel scaffolds as Topo I inhibitors bearing indole and sophoridinine were designed. Preliminary docking study revealed that some molecules among the designed series possessed promising Topo I inhibitor properties. Subsequently, thirty new compounds were synthesized and characterized by 1H NMR, 13C NMR, and Mass spectral analyses. The compounds were then screened for
基于作用机理,设计了新颖的支架,作为带有吲哚和槐定碱的Topo I抑制剂。初步的对接研究表明,设计系列中的某些分子具有有希望的Topo I抑制剂性能。随后,合成了30种新化合物,并通过1H NMR,13C NMR和质谱分析进行了表征。然后筛选化合物的抗增殖和酶抑制活性。结果证实了对接与活动之间的一致性以及设计策略的合理性。此外,选择化合物10b作为代表性化合物以在体外和体内测试其抗癌作用。结果显示10b在HepG2细胞衍生的小鼠模型中引起明显的S期细胞周期停滞并显着抑制肿瘤生长。
