Description

CPPHA is potent and selective positive allosteric modulator (PAM) of the mGluR5 and mGluR1 (metabotropic glutamate receptor). CPPHA can potentiate responses of mGluR5 and mGluR1 to activation of these receptors. CPPHA is developed for the research of central nervous system disorders[1][2].

IC50 & Target[1]

mGlu5 Receptor

 

In Vitro

CPPHA alone has no agonist activity[1].
CPPHA causes concentration-dependent potentiation of the response of human mGluR5 CHO cells to agonists[1].
CPPHA potentiates threshold response to glutamate in fluorometric Ca2+ assays 7- to 8-fold with EC50 values in the 400 to 800 nM range[1].
CPPHA (20 μM; 15 minutes) potentiates the response to a subthreshold concentration of DHPG (HY-12598A) on ERK and cyclic-AMP responsive element-binding protein (CREB) activity, as well as NMDA receptor subunit NR1 phosphorylation in cortical and hippocampal slices[3].

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

Western Blot Analysis[3]

Cell Line: Rat hippocampal cells
Concentration: 20 μM
Incubation Time: 15 minutes
Result: Potentiated the DHPG (20 μM)-induced increase in phosphorylation of ERK and CREB, approaching levels seen with 100 μM DHPG alone.

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 (6.15 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.
