Abstract

As our continuing research, a series of 2-aryl-8-OR-3,4-dihydroisoquinolin-2-ium bromides were evaluated for cytotoxic activity on Cancer cells and Apoptosis induction in the present study. SAR was derived also. Among them, 23 compounds showed the higher cytotoxicity on MKN-45 cells with IC50 values of 1.99-11.3μM than a standard Anticancer drug cis-platinum (IC50=11.4μM) or their natural model compound chelerythrine (IC50=12.7μM); 16 compounds possessed the medium to high activity on NB4 cells with IC50 values of 1.67-4.62μM. SAR analysis showed that both substitution patterns of the N-aromatic ring and the type of 8-OR significantly impact the activity. AO/EB staining and flow cytometry analysis with Annexin V/PI double staining showed that the compounds were able to induce Apoptosis in a concentration-dependent manner. The results above suggested that the title compounds are a class of promising compounds for the development of new anti-cancer drugs.
