2. Rhapontigenin

Rhapontigenin is a natural analog of resveratrol with anticancer, antioxidant, antifungal and antibacterial activities. Rhapontigenin is amechanism-based, potent and selective cytochrome P450 1A1 inactivator (IC50  = 400 nM). Rhapontigenin exhibits 400-fold and 23-fold selectivity for P450 1A1 over P450 1A2 and P450 1B1, respectively.

Description

Rhapontigenin is a natural analog of resveratrol with anticancer, antioxidant, antifungal and antibacterial activities. Rhapontigenin is amechanism-based, potent and selective cytochrome P450 1A1 inactivator (IC50  = 400 nM). Rhapontigenin exhibits 400-fold and 23-fold selectivity for P450 1A1 over P450 1A2 and P450 1B1, respectively[1].

In Vitro

Rhapontigenin (0-250 μM; 24 hours) demonstrates concentration-dependent?anti-cancer?activity with an IC50 115μM in HEP G2 cells[1].
? Rhapontigenin (20 μM; 20 hours) pre-treatment decreases TGF-β triggered increased snail expression in diverse cancer cells[2].
? Rhapontigenin (0-20 μM; 6 hours) inhibits TGF-β-induced expression of N-cadherin, vimentin, and CA9 in a dose-dependent manner[2].
? Rhapontigenin inhibits ADP- and collagen-induced platelet aggregation with IC50 values of 4 and 70 μg/ml, respectively[3].
? Rhapontigenin demonstrates a strong inhibitory activity on the 13-hexosaminidase release induced by DNP-BSA, it exhibits IC50 value of 0.03 mM in RBL 2H3 cells[3].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.08 mg/mL (8.05 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.08 mg/mL (8.05 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
