Product Description
Ginsenoside Rb3 is found in Panax ginseng CA Meyer. Ginsenoside Rb3 inhibits TNFα-induced NF-κB transcriptional activity in 293T cell line with IC50 of 8.2 μM. Ginsenoside Rb3 also inhibits the induction of COX-2 and iNOS mRNA.
Biological Activity I Assay Protocols (From Reference)
ln Vitro
Utilizing human kidney 293T cells, the inhibitory effect of ginsenoside Rb3 (0.1–10 μM) is tested on the nuclear factor kappa–light chain enhancer–induced activity of activated B cell (NF-κB) luciferase reporter gene. Measurement of effects. Ginsenoside Rb3 exhibited noteworthy activity, demonstrating an IC50 of 8.2 μM. Following treatment of HepG2 cells with TNF-α (10 ng/mL) route (mRNA) induction, ginsenoside Rb3 also inhibited cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) messenger ribose in a dose-dependent manner [1]. In a dose-dependent manner, ginsenoside Rb3 (0.1–10 μM) dramatically enhanced cell survival and prevented the release of kinase dehydrogenase (LDH). The viability of PC12 cells as determined by MTT decrease was found to be considerably lower following exposure to oxygen and increased glucose (OGD)/OGD-Rep. On the other hand, pretreatment of cells with 0.1, 1, and 10 μM of ginsenoside Rb3 dramatically disturbed the cytotoxicity generated by OGD/OGD-Rep, and this toxicity was reduced in a concentration-dependent way. In contrast to sensors, the death rate rose to 52.8%±5.6%, 64.6%±5.7%, and 76.4%±8.8%, in that order[2].
ln Vivo
The primary compound identified from Gynostemma pentaphyllum is ginsenoside Rb3, which has the ability to significantly enhance the contaminated microenvironment and cause anti-polyposis in ApcMin/+ mice. Ginsenoside Rb3 was administered to mice treated at six weeks of age prior to the development of intestinal polyps. Changes in the mice's body weight, water and food intake were tracked. Throughout the trial, no Rb3/Rd-related weight gain in mice was seen. Furthermore, there were no differences in food or water consumption among the treated rats. However, ginsenoside Rb3 therapy effectively decreased the size and quantity of polyps [3].

Additional Infomation
Ginsenoside Rb3 is a ginsenoside found in Panax species that is dammarane which is substituted by hydroxy groups at the 3beta, 12beta and 20 pro-S positions, in which the hydroxy groups at positions 3 and 20 have been converted to the corresponding beta-D-glucopyranosyl-(1->2)-beta-D-glucopyranoside and beta-D-xylopyranosyl-(1->6)-beta-D-glucopyranoside respectively, and in which a double bond has been introduced at the 24-25 position. It has a role as a plant metabolite, an antioxidant, an antidepressant, a cardioprotective agent, a NMDA receptor antagonist and a neuroprotective agent. It is a 12beta-hydroxy steroid, a beta-D-glucoside, a disaccharide derivative, a ginsenoside and a tetracyclic triterpenoid. It derives from a hydride of a dammarane.
Gypenoside IV has been reported in Panax japonicus and Gynostemma pentaphyllum with data available.

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:

  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
