产品介绍
Ginsenoside Rb3 是从Panax ginsengC. A. Meyer 中提取的。在 293T 细胞系中 Ginsenoside Rb3 抑制 TNFα 诱导的NF-κB转录活性,IC50为 8.2 μM。Ginsenoside Rb3 还抑制COX-2iNOSmRNA的诱导。
生物活性

Ginsenoside Rb3 is extracted from steamedPanax ginsengC. A. Meyer. Ginsenoside Rb3 exhibits inhibitory effect on TNFα-inducedNF-κBtranscriptional activity with anIC50of 8.2 μM in 293T cell lines. Ginsenoside Rb3 also inhibits the induction ofCOX-2andiNOSmRNA.

体外研究
(In Vitro)

Ginsenoside Rb3 (0.1-10 μM) is tested for inhibition of tumor necrosis factor-α (TNF)-induced nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) luciferase reporter activity using a human kidney 293T cell-based assay. Ginsenoside Rb3 shows the significant activity with an IC50of 8.2 μM. Ginsenoside Rb3 also inhibits the induction of cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) messenger Ribonucleic acid (mRNA) in a dose-dependent manner after HepG2 cells have been treated with TNF-α (10 ng/mL)[1]. Ginsenoside Rb3 (0.1-10 μM) significantly increases cell viability and inhibits lactate dehydrogenase (LDH) release in a dose-dependent manner. PC12 cell viability as determined by MTT reduction is also markedly decreased after the cell is exposed to oxygen and glucose deprivation (OGD)/OGD-Rep. But, when the cells are pretreated with Ginsenoside Rb3 (0.1, 1, and 10 μM), OGD/OGD-Rep induced cell toxicity is significantly attenuated, which is concentration-dependently attenuated by Ginsenoside Rb3 treatment. The viabilities are raised to 52.8%±5.6%, 64.6%±5.7%, and 76.4%±8.8%, respectively, compared with the control group[2].

体内研究
(In Vivo)

Ginsenosides Rb3 is a major compound isolated fromGynostemma pentaphyllumthat holistically improves gut microenvironment and induces anti-polyposis in ApcMin/+mice. Six-weeks-old mice are subjected to Rb3 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/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 Rb3 treatments[3].
