overview | turmeric, known as DioscoreazingiberensisC.H.Wright, is a plant of the genus Dioscorea of the Dioscoreaceae family and is a unique wild plant resource in China. Diosgenin (Deltonin) is one of the various saponins contained in Dioscorea zingiberensis. Dioscin triangularis has a variety of pharmacological activities in the fight against cardiovascular diseases, such as: protecting vascular endothelial cells, lowering blood lipids, preventing and treating thrombosis, improving coronary blood supply, and preventing and treating myocardial infarction. |
biological activity | Deltonin is a steroidal saponin obtained from Dioscorea zingiberensis, which can inhibit the activation of ERK1/2 and AKT and has anti-tumor activity. |
target | ERK1 ERK2 Akt Human Endogenous Metabolite |
in vitro study | Deltonin inhibits ERK1/2 and AKT activation. Deltonin (0.5-8 μM) significantly inhibits the proliferation of several colon cancer cell lines including SW480, SW620, LOVO and C26, with IC 50 s of 1.3, 1.29, 2.11 and 1.22 μ m. Deltonin also uses G2-M phase arrest and induces apoptosis in C26 cells. Deltonin (0-5μ m) decreases the phosphorylation of akt and erk1/2 levels in mdab-mb-231 cells. Deltonin (0.5-8μ m) also dose-dependently inhibits the proliferation, and uses apoptosis with ROS production in-mabmb 231 cells. |
in vivo study | Deltonin (20 and 40 mg/kg, p.o.) reduces the tumor growth of 37.7% and 56.7%, and problems a 50-day survival rate of 60% and 50%, respectively, in ice. Deltonin also inhibits angiogenesis in ice. |
