In vitro study | Pulsatilla saponin D (SB365) shows apoptotic effect accompanied by increased evidence of cleaved caspase-3 and poly (ADP ribose) polymerase. Pulsatilla saponin D (SB365) strongly inhibits c-Met expression in gastric cancer cells. 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) . Pulsatilla saponin D (SB365) shows anti-angiogenic activity by decreasing the expression of HIF-1α and VEGF. Pulsatilla saponin D (0.3 ng/mL to 10 μg/mL) exhibits anti-tumor activity in NSCLC cancer cells. Cell Cytotoxicity Assay 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 ED 50 value of 6.3 μg/mL for A-549 cells. |
In vivo study | Pulsatilla saponin D (6.4 mg/kg) exhibits anti-tumor activity in Lewis lung carcinoma model. Animal Model: 2x2x2 mm 3 tumor fragments of a Lewis lung carcinoma (LLC) transplanted s.c. into the auxiliary region of the BDF1 mice. 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%). |
