Description

Domperidone (R33812) is an orally active and selective dopamine-2 receptor antagonist. Domperidone acts as an antiemetic and a prokinetic agent through its effects on the chemoreceptor trigger zone and motor function of the stomach and small intestine[1].

IC50 & Target[1]

D2 Receptor

 

In Vitro

Cardiac Na+ channels are common targets of therapeutics inducing cardiotoxicity[3].
Domperidone (0-1000 μM) displays concentration- and state-dependent inhibitory of Nav1.5 in Human embryonic kidney HEK293 cells[3].
Domperidone (0, 10, 100 μM) displays tonic and use-dependent block to Na currents in rat cardiomyocytes with a IC50 of 312 μM[3].

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

In Vivo

Unlike Metoclopramide, Domperidone (R33812) does not cause any adverse neurological symptoms as it has minimal penetration through the blood-brain barrier[1].
Domperidone acts as both an antiemetic and an upper gastrointestinal tract prokinetic agent. It is rapidly absorbed after oral administration, and few side effects have been reported[2].

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: ≥ 2.75 mg/mL (6.46 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.75 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (27.5 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: ≥ 2.75 mg/mL (6.46 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.75 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (27.5 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.
