| In Vitro | Pyropheophorbide-a methyl ester (2 μM; 12 h) inhibits the cell cycle progression from the G0/G1-phases and induces apoptosis at the light dosage of 55.6 kJ/m2 in PC-3M cells[2]. Pyropheophorbide-a methyl ester (0.2-15 μM; 20 h) has no significant dark cytotoxicity in NCI-h446 cells[1]. Pyropheophorbide-a methyl ester (0.1-15 μM; 20 h) mediates a dose-dependent photocytotoxicity in the NCI-h446 cells[1]. Pyropheophorbide-a methyl ester (2-4 μM; 0-24 h) induces apoptosis of NCI-h446 cells in a time-dependent manner[1]. Pyropheophorbide-a methyl ester (0.5-4 μM; 0-20 h) shows a photocytotoxicity in PC-3M cells[2]. Apoptosis Analysis[1] Cell Line: PC-3M cells Concentration: 2 μM Incubation Time: 12 h Result: Apoptosis rate was about 0.27%, 6.15%, 20.49%, 50.76%, 65.39%, 64.92%, and 64.37% at 1, 3, 6, 12, 18, and 24 h posttreatment, respectively under the conditions of LC75 (2 μM+55.6 kJ/m2). |
| In Vivo | Pyropheophorbide-a methyl ester (15 mg/kg; tail vein and topical injection) inhibits the growth of PC-3M tumors in mice[2]. Animal Model: Male BALB/c nude mice (6-8 weeks, 16-20 g) bearing PC-3M tumor[2] Dosage: 15 mg/kg Administration: Tail vein injection and topical injection Result: The tumor volume and the weight inhibition rate were 46.78%, 41.84% in tail vein injection group and 78.66%, 72.07% in topical injection group, respectively. |
