Description

RG-12525 is a a specific, competitive and orally effective antagonist of the peptidoleukotrienes, LTC4, LTD4 and LTE4, inhibiting LTC4-, LTD4- and LTE4-inducd guinea pig parenchymal strips contractions, with IC50s of 2.6 nM, 2.5 nM and 7 nM, respectively; RG-12525 is also a peroxisome proliferator-activated receptor gamma (PPAR-gamma) agonist with IC50 of appr 60 nM and a potent inhibitor of CYP3A4, with a Ki value of 0.5 µM.

IC50 & Target

IC50: appr 60 nM (PPAR-γ)[2]
In Vitro

RG 12525 competitively inhibits 3H-LTD4 binding to lung membranes (Ki = 3.0 +/- 0.3 nM) and competitively antagonizes the spasmogenic activity of LTC4, LTD4 and LTE4 on lung strips (KB values = 3 nM) with greater than 8000 fold selectivity[1]. RG 12525 (2.5 µM or 25 µM) inhibits the microsomal activity of CYP2C9 and -3A4, but does not significantly inhibit CYP1A2,-2A6, -2C19, or -2D6. RG 12525 (25 µM) also causes a substantial amount of inhibition at the 5 and 10 µM midazolam concentrations[2].

In Vivo

RG 12525 orally inhibits LTD4 induced wheal formation (ED50 = 5 mg/kg with a t1/2 = 10 hrs at 9 mg/kg), LTD4 induces bronchoconstriction (ED50 = 0.6 mg/kg), and anaphylactic death (ED50 = 2.2 mg/kg with a t1/2 = 7 hrs at 10 mg/kg) and antigen induces bronchoconstriction (ED50 = 0.6 mg/kg)[1]. RG 12525 inhibits antigen-induced mortality in the systemic anaphylaxis model with an ED50 (95% confidence interval) = 2.2 (0.8-6.4) mg/kg. RG 12525 also protects against LTD4-induced bronchoconstriction in a model measuring changes in pulmonary function with an ED50 = 0.6 (0.4-1.0) mg/kg[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 (4.91 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 (4.91 mM); Suspended solution; Need ultrasonic

    This protocol yields a suspended solution of 2.08 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

    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.
