Ro 5212773
Based on 1 publication(s) in Google Scholar
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.

Biological Activity
|
TAAR1 |
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.
Please enter the basic information of animal experiments:
