产品简介:
抑制 TNFα 诱导的 NF-κB 转录活性。抑制 COX-2 和 iNOS mRNA 的表达。 还抑制 Ca2+ 内流。 Ginsenoside Rd is a 26S proteasome inhibitor and TRPm7 antagonist found in species of Panax. It shifts cytokine production toward Th2 phenotype, increases expression of BDNF and NGF, prevents tau phosphorylation, and decreases infarct zie and mycotye apoptosis in myocardial ischemia/reperfusion models.

CYP2D6:58 μM (IC50)

体外研究:
Ginsenoside Rd is one of the most abundant ingredients of Panax ginseng. Ginsenoside Rd significantly inhibits TNF-α-induced NF-κB transcriptional activity with an IC50 of 12.05±0.82 in HepG2 cells. Ginsenoside Rd also inhibits expression of COX-2 and iNOS mRNA and iNOS promoter activity in a dose-dependent manner. To determine nontoxic concentrations, HepG2 cells are treated with various concentrations (0.1, 1, and 10 μM) of compounds (e.g., Ginsenoside Rd) and cell viability is measured using an MTS assay. No compounds are significantly cytotoxic at up to 10 μM, indicating that NF-κB inhibition is not due to cell toxicity. Ginsenoside Rd is one of the most abundant ingredients of Panax ginseng, protects the heart via multiple mechanisms including the inhibition of Ca2+ influx. Ginsenoside Rd reduces ICa,L peak amplitude in a concentration-dependent manner (IC50=32.4±7.1 μM). Ginsenoside Rd exhibits an inhibition against the activity of CYP2D6 in human liver microsomes with an IC50 of 58.0±4.5 μM, a weak inhibition against the activity of CYP1A2, CYP3A4, and CYP2C9 in human liver microsomes with IC50s of 78.4±5.3, 81.7±2.6, and 85.1±9.1, respectively, and an even weaker inhibition against the activity of CYP2A6 in human liver microsomes with an IC50 value of more than 100 μM.
体内研究:
Ginsenosides Rd is a major compound isolated from Gynostemma pentaphyllum that holistically improves gut microenvironment and induces anti-polyposis in ApcMin/+ mice. Six-weeks-old mice are subjected to Ginsenoside Rd treatment, before the appearance of the intestinal polyps. All the mice are monitored for food intake, water consumption, and weight changes. Throughout the experiment, no Rb3/ Ginsenoside Rd-associated weight loss in mice is observed. In addition, none of the treated mice show variations in food and water consumption. Whereas, the number and size of the polyps are effectively reduced by Ginsenoside Rd treatments.
