体外研究 (In Vitro) | Formononetin is one of the major isoflavonoid constituents isolated from Astragalus membranaceus and has been demonstrated diverse pharmacological benefits. Formononetin possesses anti-angiogenic activity in human colon cancer cells. Formononetin also promotes cell cycle arrest via downregulation of Akt/Cyclin D1/CDK4 in human prostate cancer cells[1]. Formononetin (25 to 150 μM) markedly decreases the proliferation of endothelial cells stimulated by FGF2[1].
Cell Viability Assay[1] Cell Line: | HUVECs | Concentration: | 0, 10, 25, 50, 75, 100, and 150 μM | Incubation Time: | | Result: | Significantly decreased the proliferation of HUVECs stimulated by FGF2 in a dose-dependent manner, while had little inhibitory effects on HUVECs that were not stimulated by FGF2. |
|
体内研究 (In Vivo) | Formononetin dramatically suppresses tumor volumes and the Formononetin-treated group tumor weight are significantly inhibited compared with the vehicle group . Formononetin treatment is well tolerated, and there is no significant difference in weight between vehicle group and formononetin treated groups[1].
Animal Model: | BALB/c nude mice bearing MDA-MB-231 xenografts[1] | Dosage: | 100 mg/kg | Administration: | Treated daily by intragastric administration for 25 days | Result: | Inhibited breast cancer growth and angiogenesis in vivo. |
