Abstract: Based on our previous study and the binding mode of camptothecin with Topo I, a series of novel sophoridine imine derivatives containing conjugated planar structure were designed, synthesized and tested for their in vitro anticancer activity. The results showed that most of the derivatives displayed potent activity. In particular, compounds 10b exhibited excellent anti-proliferative activities with IC50 5.7 µM and 8.5 µM against HepG-2 and HeLa cell lines, respectively. Molecular docking studies revealed that the introduction of conjugated planar structure could form π-π stacking interaction with DNA, leading to the improvement of biological activity. Its mode of action was to inhibit the activity of DNA Topo I, followed by the G0/G1 phase arrest. This work provides a theoretical basis for structural optimizations and exploring anticancer pathways of this kind of compound and 10b could emerge as promising lead compounds for the development of novel Topo I inhibitors.
