Pulsatilla saponin D (SB365) 可从Pulsatilla chinensis根部分离得到,具有抗癌活性。
生物活性 | Pulsatilla saponin D (SB365), isolated from the root ofPulsatilla chinensis, is an anti-tumor agent[1][2][3][4]. |
体外研究 (In Vitro) | Pulsatilla saponin D (SB365) shows apoptotic effect accompanied by increased evidence of cleaved caspase-3 and poly (ADP ribose) polymerase[1]. Pulsatilla saponin D (SB365) strongly inhibits c-Met expression in gastric cancer cells[1]. Pulsatilla saponin D (SB365) strongly suppresses the growth and proliferation of 5 human pancreatic cancer cell lines (MIAPaCa-2, BXPC-3, PANC-1, AsPC-1 and HPAC)[2]. Pulsatilla saponin D (SB365) shows anti-angiogenic activity by decreasing the expression of HIF-1α and VEGF[3]. Pulsatilla saponin D (0.3 ng/mL to 10 μg/mL) exhibits anti-tumor activity in NSCLC cancer cells[4].
Cell Cytotoxicity Assay[4] Cell Line: | A-549, SKMEL-2, MCF-7, and Lewis lung carcinoma (LLC) cells. | Concentration: | 0.3 ng/mL to 10 μg/mL. | Incubation Time: | 72 h. | Result: | Exhibited an ED50value of 6.3 μg/mL for A-549 cells. |
|
体内研究 (In Vivo) | Pulsatilla saponin D (6.4 mg/kg) exhibits anti-tumor activity in Lewis lung carcinoma model[4].
Animal Model: | 2x2x2 mm3tumor fragments of a Lewis lung carcinoma (LLC) transplanted s.c. into the auxiliary region of the BDF1 mice[4]. | Dosage: | 6.4 mg/kg. | Administration: | Intraperitoneally on the 1 st to 7 th and 9 th to 14 th day. | Result: | Had such a potent antitumor effect (IR, 82 %) on a solid tumor, which is higher than Adriamycin (IR, 64%). |
