Ro 5212773

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.

How to use

In Vitro:

Ro 5212773 (EPPTB) suppresses the excitability of hippocampal pyramidal neurons. EPPTB also reduceds seizure-like events (SLEs) and seizure activity. Ro 5212773 blocks the TAAR1-mediated activation of an inwardly rectifying K+ current. 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.
