  4. Maropitant

Maropitant is a selective and orally active neurokinin (NK1) receptor antagonist. Maropitant acts by blocking the binding of substance P within the emetic center and the chemoreceptor trigger zone (CRTZ). Maropitant is highly effective in preventing vomiting.

Description

Maropitant is a selective and orally active neurokinin (NK1) receptor antagonist. Maropitant acts by blocking the binding of substance P within the emetic center and the chemoreceptor trigger zone (CRTZ). Maropitant is highly effective in preventing vomiting[1][2].

IC50 & Target

NK1

 

In Vivo

Treatment with 1 mg/kg Maropitant citrate, significantly reduces the size of ulcerative dermatitis (UD) lesions in mice. Intravenous Maropitant decreases MAC by 16%. In contrast, epidural administration of either saline or Maropitant does not change the MAC (2.17% and 1.92 %, respectively).

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    90% Corn Oil

    Solubility: ≥ 2.5 mg/mL (5.33 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

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.
