Dioscoreaceae

Dihydroresveratrol, a potent phytoestrogen, is a hormone receptor modulator. Dihydroresveratrol exhibits proliferative effects in androgen-independent prostate and breast cancer cells at picomolar and nanomolar concentrations.

Pseudoprotodioscin, a furostanoside, inhibits SREBP1/2 and microRNA 33a/b levels and reduces the gene expression regarding the synthesis of cholesterol and triglycerides.

Deltonin, a steroidal saponin, isolated from Dioscorea zingiberensis, has antitumor activity; Deltonin inhibits ERK1/2 and AKT activation.

Zingiberen Newsaponin (Zingiberensis newsaponin) is an orally active type of steroid saponin compound. Zingiberen Newsaponin exerts anti-hepatocellular carcinoma (HCC) effects by inhibiting autophagy and the AKR1C1/JAK2/STAT3 pathway. Zingiberen Newsaponin activates oxidative stress (upregulates ROS and MDA) and mitochondrial pathways, promoting cancer cell apoptosis. Zingiberen Newsaponin alleviates cerebral ischemia-reperfusion (I/R) injury by decreasing the concentration of pro-inflammatory cytokines and inhibits NF-κB. Zingiberen Newsaponin can enhance the activity of SOD, eliminate free radicals and protect nerve cells. Zingiberen Newsaponin induces platelet aggregation.

Protoneogracillin, a furostanol glycoside, shows anti-fungal activity against the plant pathogenic fungus P.oryzae (MMDC=94.0 μM) and cytotoxic activity on K562 cancer cells (IC₅₀=6.6 μM).

Pseudoprotodioscin (Standard) is the analytical standard of Pseudoprotodioscin. This product is intended for research and analytical applications. Pseudoprotodioscin, a furostanoside, inhibits SREBP1/2 and microRNA 33a/b levels and reduces the gene expression regarding the synthesis of cholesterol and triglycerides.

Dioscorea opposita extract is an extract isolated fromDioscorea opposita.

Dioscorea bulbifera polysaccharide is a polysaccharide derived from Dioscorea bulbifera.

Batatasin V is a natural product that could be isolated from dormant bulbils of Chinese yam (Dioscorea batatus). Batatasin V has the effect of inhibiting plant growth.

Colocasia esculenta polysaccharide is a polysaccharide derived from Colocasia esculenta.

Spongipregnoloside B is a pregnane diglycoside found in the rhizomes of Dioscorea spongiosa. Spongipregnoloside B can be used in osteoporosis research.

Cholesterol (from plant) is the major sterol in mammals. It is making up 20-25% of structural component of the plasma membrane. Plasma membranes are highly permeable to water but relatively impermeable to ions and protons. Cholesterol (from plant) plays an important role in determining the fluidity and permeability characteristics of the membrane as well as the function of both the transporters and signaling proteins. Cholesterol (from plant) is also an endogenous estrogen-related receptor α (ERRα) agonist.

Progenin II is a steroidal saponin found in the rhizomes of Dioscorea panthaica.

Protoneodioscin is a furostanol saponin found in the rhizomes of Dioscorea collettii var. hypoglauca. It exhibits selective activity against various cancer cell lines, including leukemia, but shows no activity against colon and renal cancer cells. Protoneodioscin can be used in research on cancers such as leukemia.

3,2'-Dihydroxy-4,5-dimethoxybibenzyl is a natural phenolic compound.

Diosbulbin I is a furan-type nor-diterpenoid compound that can be naturally extracted from the tubers of Dioscorea bulbifera L. Dioscorea bulbifera L. is traditionally used to research thyroid diseases and tumors.

Taccabulin A is a natural chalcone.

Diosbulbin A, a diterpenoid lactone, is one of main hepatotoxic constituent of Dioscorea bulbifera.

Zizyvoside I is a compound found in Dioscorea septemloba. Zizyvoside I is a potential anti-inflammatory agent.
