based on molecular similarity strategy. Incorporation of nitrate into 1,3-dioxyxanthones with electron-donating groups at 6–8 position brought about synergistic anticancer effect. Among them, compound 4g-4 was confirmed the most active agent against HepG-2 cells growth with an IC50 of 0.33 ± 0.06 μM. It dose-dependently increased intramolecular NO levels. This activity was attenuated by either NO scavenger
