In this study, 10 aporphine alkaloids were synthesized with 1, 2-methylenedioxy substituent in ring A and 9, 10, 11-position with different substituents in ring D. Their structures were determined by ESI-MS,13C NMR and 1 H NMR.The potencial antitumor activity of these compounds against B16F10 melanoma cells were evaluated by MTT assay, and their structure-activity relationship was further analyzed.Meanwhile, zebrafish acute toxicity test was conducted to evaluate the safety of the active compounds.The results showed that some compounds had strong inhibitory activity on tumor cells, and could significantly inhibit the proliferation of B16F10 melanoma cells.Compound IVa has the best anti-melanoma activity with wide safety range, and can be used as a lead compound for further study on anti-proliferation of B16F10 melanoma cells.
