Description

GPR52 agonist-1 is a potent, orally active and blood-brain barrier (BBB) penetrant GPR52 agonist with an pEC50 value of 7.53. GPR52 agonist-1 affects cAMP accumulation through direct interaction with GPR52. GPR52 agonist-1 can significantly suppress Methamphetamine-induced hyperactivity in mice. Antipsychotic activity[1].

IC50 & Target

pEC50: 7.53 (GPR52)[1]

In Vivo

GPR52 agonist-1 (compound 7m) (3, 10, and 30 mg/kg; PO; single dosage) attenuates Methamphetamine-induced hyperlocomotion in mice[1].
GPR52 agonist-1 (0.1 mg/kg, IV and 1 mg/kg, PO; single dosage) exhibits good oral pharmacokinetic profile with an Cmax of 108.1 ng/mL, an AUC0-8h of 613.7 ng·h/mL, and an F (bioavailability) of 73% in mouse[1].

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

Animal Model: Male ICR mice (7-8 weeks; subcutaneously injected with 2 mg/kg Methamphetamine after 60 min administration)[1]
Dosage: 3, 10, and 30 mg/kg
Administration: PO; single dosage
Result: Attenuated Methamphetamine-induced hyperlocomotion dose-dependently.
Did not show significant cataleptogenic effects even at a dose of 100 mg/kg and had a low risk of extrapyramidal side effects.

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: ≥ 2.5 mg/mL (5.51 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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% Corn Oil

    Solubility: ≥ 2.5 mg/mL (5.51 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.
