Description

(Rac)-Benpyrine, a racemate of Benpyrine, is a potent and orally active TNF-α inhibitor. (Rac)-Benpyrine has the potential for TNF-α mediated inflammatory and autoimmune disease research[1].

In Vitro

(Rac)-Benpyrine (Compound 001; 5-10 μM; 24 hours) treatment inhibits the expression level of TNF-α downstream pathway protein NF-κB in the nucleus in RAW264.7 macrophages[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

(Rac)-Benpyrine (Compound 001; 25-50 mg/kg; oral gavage; daily; for 3 weeks; Kunming mice) treatment obviously reduces the inflammatory cytokines IFN-γ, IL-1β and IL-6 in the blood serum, and the anti-inflammatory factor IL-10 is obviously increased, the foot swelling degree of the arthritis part is also obviously slowed down, and the weight index increase caused by the arthritis also has no obvious reduction[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Kunming mice (7-8 weeks) treated with bovine type II collagen and a CFA complete adjuvant[1]
Dosage: 25 mg/kg, 50 mg/kg
Administration: Oral gavage; daily; for 3 weeks
Result: The inflammatory cytokines IFN-γ, IL-1β and IL-6 in the blood serum were obviously reduced, and the anti-inflammatory factor IL-10 was obviously increased.

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: ≥ 1.25 mg/mL (4.05 mM); Clear solution

    This protocol yields a clear solution of ≥ 1.25 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (12.5 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: ≥ 1.25 mg/mL (4.05 mM); Clear solution

    This protocol yields a clear solution of ≥ 1.25 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (12.5 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.
