Ginsenoside Rg3

Research use only, not for human use.

Ginsenoside Rg3 possess an ability to inhibit the lung metastasis of tumor cells via inhibition of the adhesion and invasion of tumor cells.

Ginsenoside Rg3 is a K 7.1 channel activator, γ2 GABA-A receptor agonist, and a α10 nAChR antagonist found in Panax. It exhibits a wide variety of biological activities, including decreasing expression of pro-inflammatory cytokines, reducing oxidative stress, and inhibiting tubular formation and migration of endothelial progenitor cells.(In Vitro):Ginsenoside Rg3 plays an important role in its effect on the Na+ channel. Treatment with Ginsenoside Rg3 reversibly inhibits the inward Na+ peak current (INa) with an IC50 of 32.2±4.5 μM, and the inhibition is voltage-dependent. Ginsenoside Rg3 at 100 μM inhibits the hKv1.4 channel currents by an average of 65%.The Ginsenoside Rg3 effect is concentration-dependent and reversible. The IC50 value and Hill coefficient are 32.6±2.2 μM and 1.59±0.13, respectively. Ginsenoside Rg3 shows the significant inhibition of NF-κB activity thereby reduced COX-2 expression. To examine the cytotoxicity of Ginsenoside Rg3 on IL-1β-induced inflamed A549 cells, the cells are firstly treated with IL-1β (10?ng/mL) for 4?h and treated with 100 to 900?ng/mL concentration of Ginsenoside Rg3 for 12?h. Cell viability is analyzed using an MTT assay. There is no observed cytotoxicity of Ginsenoside Rg3 in IL-1β-induced inflamed A549 cells compared to only PBS-treated cells (Con).To obtain the anti-inflammatory effects of Ginsenoside Rg3 on inflammation induced human lung epithelial cells, A549 cells inflammation is induced by IL-1β (10?ng/mL) and then treated by 5?μM of Dexamethasone (Dex) or 900?nM of Rg3. The NF-κB activation is analyzed by a western blot analysis to evaluate the effect of Ginsenoside Rg3 treatment on A549 cells. Phospho-NF-κB p65/total NF-κB p65 densitometry in the cells treated with Rg3 shows the significant decrease compared to IL-1β-induced inflamed A549 cells. The meaning of reducing the ratio of p-p65/p65 by Rg3 treatment is associated with NF-κB activation. Ginsenoside Rg3 also downregulates the expression of COX-2 effectively.(In Vivo):Ginsenoside Rg3 ((20S)-Rg3) is an Aβ-lowering Natural Compound. APP/PS1 mice are treated with Ginsenoside Rg3 once a day for 4 weeks by intraperitoneal injection (10 mg/kg/day). Aβ ELISA analysis of brain tissues reveal that Ginsenoside Rg3 treatment results in a significant reduction of Aβ40 and Aβ42 in the brain.
