RO5263397, or RO-5263397, is a trace amine-associated receptor 1 (TAAR1) partial agonist which is used in scientific research.^[1]^[2] Its EC₅₀Tooltip half-maximal effective concentration values are 0.12 nM for the mouse TAAR1 (mTAAR1), 35 nM for the rat TAAR1 (rTAAR1), and 17 to 85 nM for the human TAAR1 (hTAAR1).^[2] Similarly to other TAAR1 agonists like RO5166017 and RO5256390, RO5263397 shows aversive effects in animals.^[3]^[4]
