A ginsenoside metabolite that has been linked to endothelial cell function via the glucocortoid receptor (GR) and the oestrogen receptor (ER).
Application
20S-Protopanaxatriol (g-PPT), a dammarane-type tetracyclic terpene sapogenin, may be used to study its binding to and modulation of cell function via glucocortoid (GR) and oestrogen (ER) receptors.
Biochem/physiol Actions
A metabolites of ginsenoside, protopanaxatriol (g-PPT), could modulate endothelial cell functions through the glucocorticoid receptor (GR) and oestrogen receptor (ER).
Estrogens exert many of their behavioral effects by binding to nuclear estrogen receptor (ER) proteins, ERalpha and ERbeta. Recent studies involving ER knockout mice and selective ER agonists suggest that estradiol's anorexigenic effect is mediated via activation of ERalpha. To
We previously reported that 17β-estradiol (E2) is pronociceptive in a visceral pain model in the rat. Subcutaneously (s.c.) administered E2 reversed the decrease in the colorectal distention (CRD)-evoked visceromotor response produced by ovariectomy (OVx) and CRD-induced nociceptive responses were greater

Ginsenoside Re (G-Re) improved the memory function of experimental animals in a preclinical study. Several types of saponins including G-Rg1, G-Rg2, G-F1, G-Rh1, and protopanaxatriol (PPT) may be the metabolites of G-Re according to reports from preclinical trials. In order

Ginseng, a commonly used natural product, has been frequently reported to induce herb-drug interaction with many clinical drugs. The intestinal bacterial metabolites of ginsenosides have been widely regarded as the substance basis for ginseng-drug interactions. To date, little is known

Ginseng, the root of Panax ginseng C. A. Meyer (Araliaceae), is one of the most important traditional medicines and functional foods. A detailed phytochemical investigation on the roots of P. ginseng led to the isolation of 6 new natural protopanaxatriol
