Plumbagin (2-Methyljuglone) 是从Plumbago zeylanica中得到的萘醌类物质,具有抗肿瘤、抗增殖活性。
生物活性 | Plumbagin (2-Methyljuglone) is a naphthoquinone isolated fromPlumbago zeylanica, exhibits anticancer and antiproliferative activities[1]. |
体外研究 (In Vitro) | Plumbagin (0, 5, 10, and 15 μM) induces apoptosis of prostate cancer cell lines, such as DU145, CWR22rv1 and LNCaP, in a dose-dependent manner[1]. Plumbagin (5, 20 μM) obviously inhibits the invasion of PC3, DU145, and CWR22rv1 cells[1].
Apoptosis Analysis[1] Cell Line: | DU145, CWR22rv1, LNCaP and RWPE-1 cells | Concentration: | 0, 5, 10, and 15 μM | Incubation Time: | 24 hours | Result: | Dose-dependently induced apoptosis of DU145, CWR22rv1 and LNCaP, but showed no effect on RWPE-1 cells at up to 20 μM. |

体内研究 (In Vivo) | Plumbagin (2 mg/kg, i.p., five days a week for 11 weeks) inhibits the growth of tumor in male athymic nude mice[1]. Plumbagin (2 mg/kg, i.p., five days a week for 11 weeks) inhibits expression of PKCε, suppresses JAK-2 and Stat3 phosphorylation, and activates Stat3, PCNA, VEGF and MMP-9 in mice[1].
Animal Model: | Male athymic nude mice bearing DU145 cells[1] | Dosage: | 2 mg/kg | Administration: | I.P. after 3 days post cell implantation, five days a week. | Result: | Delayed tumor growth by 3 weeks, and reduced tumor weight and volume in mice. |
