Description

Ro 67-7476 is a potent positive allosteric modulator of mGluR1 and potentiates glutamate-induced calcium release in HEK293 cells expressing rat mGluR1a with an EC50 of 60.1 nM[1][2]. Ro 67-7476 is a potent P-ERK1/2 agonist?and activates ERK1/2 phosphorylation in the absence of exogenously added glutamate (EC50=163.3 nM)[3].

IC50 & Target[1]

mGluR1a

60.1 nM (EC50)

In Vitro

In the Purkinje cells of rat cerebellar slices, Ro 67-7476 increases the amplitude of mGluR1 excitatory postsynaptic potentials (EPSCs) evoked by 2,3-dihydroxy-6-nitro-7-sulfamoylbenzoquionxaline, picrotoxin, or AP5[3].
Ro 67-7476 activates ERK1/2 phosphorylation in the absence of exogenously added glutamate (EC50=163.3 nM). The EC50 value of full P-ERK1/2 activation for Ro 67-7476 are nearly identical to the EC50 for calcium mobilization potentiation[3].
Ro 67-7476 increases basal cAMP production approximately by 8%. It potentiated threshold responses to glutamate in the cAMP accumulation assay, with an EC50 value of 17.7 μM[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    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.5 mg/mL (7.83 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 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.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% Corn Oil

    Solubility: ≥ 2.5 mg/mL (7.83 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.
