製品説明

Ro 5212773 (EPPTB) is a potent and selective trace amine-associated receptor 1 (TAAR1) antagonist (Ki=0.9 nM for mouse TAAR1), with no significant effects on other TAARs. TAAR1 is a G protein-coupled receptor (GPCR) that is nonselectively activated by endogenous metabolites of amino acids[1][2].

IC50 & Target

TAAR1

 

体外実験

Ro 5212773 (EPPTB) suppresses the excitability of hippocampal pyramidal neurons. EPPTB also reduceds seizure-like events (SLEs) and seizure activity[1].
Ro 5212773 blocks the TAAR1-mediated activation of an inwardly rectifying K+ current[2].
Ro 5212773 potently antagonizes cAMP production induced by activating mouse TAAR1 with 1.5 μM β-phenylethylamine (IC50=27.5 nM). cAMP levels are dose-dependently reduced by Ro 5212773 in HEK293 cells in the absence of TAAR1 agonist (IC50= 19 nM). EPPTB is significantly more potent in antagonizing cAMP production by mouse, as compared to rat (IC50= 4539 nM) and human (IC50= 7487 nM) TAAR1[2].

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 (6.61 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.
