In Vitro	Purpurin 18 methyl ester (1-5 μg/mL; 24 h) has no cytotoxicity in dark in HepG-2 cells[1]. Purpurin 18 methyl ester (1-5 μg/mL; 24 h) decreases the viability of HepG-2 cells in a concentration-dependent manner with irradiation for 10 min[1]. Purpurin 18 methyl ester (0-24 h) is released from GO- Purpurin 18 methyl ester (Pu18) composite, with rates of 47%, 22% and 30% in weak acidic condition (pH 5.6), neutral environment (pH 7.4) and weak alkali condition (pH 8.9) for 24 h, respectively[1].
