RO5166017 is an agonist of trace amine-associated receptor 1 (TAAR1).1 It binds to TAAR1 (Kis = 31, 24, 1.9, and 2.7 nM in HEK293 cells expressing the recombinant human, cynomolgus monkey, mouse, or rat receptor, respectively) and is greater than 15-fold selective for TAAR1 over a panel of 123 receptors, ion channels, and transporters at 10 µM. RO5166017 induces cAMP production in HEK293 cells expressing the recombinant human, cynomolgus monkey, mouse, or rat TAAR1 (EC50s = 55, 97, 3.3, and 14 nM, respectively). It reduces the frequency of neuronal firing in mouse ventral tegmental area (VTA) and dorsal raphe nucleus (DRN) slices (IC50s = 1.73 and 2.99 nM, respectively), which endogenously express high levels of dopaminergic and serotonergic neurons, respectively. RO5166017 (0.3 mg/kg) inhibits stress-induced hyperthermia, indicating anxiolytic-like activity, as well as reduces cocaine-induced hyperlocomotion, in mice. It also impairs expression, but not reconsolidation, of cocaine-induced place preference in rats.2

Selective TAAR1 agonists induce conditioned taste aversion
Psychopharmacology (Berl) 2022 Oct;239(10):3345-3353.PMID:36056214DOI:10.1007/s00213-022-06222-5.
Rationale: Trace amine-associated receptor 1 (TAAR1) is the best-studied receptor of trace amines, a group of biogenic amines expressed at a relatively low level in the mammalian brain. Growing evidence suggests that TAAR1 plays a critical role in various neuropsychiatric disorders. Given that selective TAAR1 agonists were shown to produce pro-cognition and antipsychotic-like effects as well as to suppress drug use and relapse, they have been proposed to be novel treatments for mental disorders such as schizophrenia and addiction. However, the aversive effects of selective TAAR1 agonists remain largely unknown. Objectives: Here, we evaluated whether the selective TAAR1 full agonist RO5166017 and partial agonist RO5263397 could induce conditioned taste aversion (CTA). Results: We found that RO5166017 and RO5263397 produced significant aversions to both saccharin and NaCl taste novelty. Furthermore, RO5166017 produced CTA to saccharin in TAAR1 heterozygous knockout (taar1±) and wild-type rats but not in TAAR1 homozygous knockout rats (taar1-/-), suggesting that TAAR1 was sufficient for the taste aversive stimulus property of RO5166017. Conclusions: Taken together, our data indicate that selective TAAR1 agonists could produce strong CTA. Our study urges careful evaluations of the aversive effects of TAAR1 agonists before translating them to clinical use for the treatment of mental disorders.
Trace amine-associated receptor 1 agonists RO5263397 and RO5166017 attenuate quinpirole-induced yawning but not hypothermia in rats
Behav Pharmacol 2017 Oct;28(7):590-593.PMID:28704278DOI:10.1097/FBP.0000000000000330.
Increasing evidence suggests that trace amine-associated receptor 1 (TAAR1) is an important modulator of the dopaminergic system. Existing molecular evidence indicates that TAAR1 regulates dopamine levels through interactions with dopamine transporters and D2 receptors. However, investigations to date have not been exhaustive and other pathways may be involved. In this study, we used a well-described set of behaviors, quinpirole-induced yawning and hypothermia, to explore the potential interaction of TAAR1 and D3 receptors, which are members of the 'D2-like' dopamine receptor subfamily. Previous studies have shown that for D2/D3 receptor agonists, the induction of yawning is a D3 receptor-mediated effect, whereas the inhibition of yawning and induction of hypothermia are D2 receptor-mediated effects. Quinpirole produced an inverted U-shaped dose-effect curve for yawning, which was shifted downward dose-dependently by each of the TAAR1 agonists RO5263397 and RO5166017. Quinpirole also produced dose-dependent hypothermia, which was not affected by either TAAR1 agonist. These results suggest that TAAR1 agonists may interact with D3 receptors and/or its downstream pathways, as opposed to D2 receptors. These findings may shed light on a previously unexplored possibility for the mechanism of TAAR1-mediated effects.
Role of TAAR1 within the Subregions of the Mesocorticolimbic Dopaminergic System in Cocaine-Seeking Behavior
J Neurosci 2017 Jan 25;37(4):882-892.PMID:28123023DOI:10.1523/JNEUROSCI.2006-16.2016.
A novel G-protein coupled receptor, trace amine-associated receptor 1 (TAAR1), has been shown to be a promising target to prevent stimulant relapse. Our recent studies showed that systemic administration of TAAR1 agonists decreased abuse-related behaviors of cocaine. However, the role of TAAR1 in specific subregions of the reward system in drug addiction is unknown. Here, using a local pharmacological activation method, we assessed the role of TAAR1 within the subregions of the mesocorticolimbic system: that is, the VTA, the prelimbic cortex (PrL), and infralimbic cortex of medial prefrontal cortex, the core and shell of NAc, BLA, and CeA, on cue- and drug-induced cocaine-seeking in the rat cocaine reinstatement model. We first showed that TAAR1 mRNA was expressed throughout these brain regions. Rats underwent cocaine self-administration, followed by extinction training. RO5166017 (1.5 or 5.0 μg/side) or vehicle was microinjected into each brain region immediately before cue- and drug-induced reinstatement of cocaine-seeking. The results showed that microinjection of RO5166017 into the VTA and PrL decreased both cue- and drug priming-induced cocaine-seeking. Microinjection of RO5166017 into the NAc core and shell inhibited cue- and drug-induced cocaine-seeking, respectively. Locomotor activity or food reinforced operant responding was unaffected by microinjection of RO5166017 into these brain regions. Cocaine-seeking behaviors were not affected by RO5166017 when microinjected into the substantia nigra, infralimbic cortex, BLA, and CeA. Together, these results indicate that TAAR1 in different subregions of the mesocorticolimbic system distinctly contributes to cue- and drug-induced reinstatement of cocaine-seeking behavior. Significance statement: TAAR1 has been indicated as a modulator of the dopaminergic system. Previous research showed that systemic administration of TAAR1 agonists could attenuate cocaine-related behaviors, suggesting that TAAR1 may be a promising drug target for the treatment of cocaine addiction. However, the specific role of TAAR1 in subregions of the mesocorticolimbic system in drug addiction is unknown. Here, we first showed that TAAR1 mRNA is expressed throughout the subregions of the mesocorticolimbic system. Then, by using a local pharmacological activation method, we demonstrated that TAAR1 in different subregions of the mesocorticolimbic system distinctly contributes to cue- and drug-induced reinstatement of cocaine-seeking behavior.
TAAR1 activation modulates monoaminergic neurotransmission, preventing hyperdopaminergic and hypoglutamatergic activity
Proc Natl Acad Sci U S A 2011 May 17;108(20):8485-90.PMID:21525407DOI:10.1073/pnas.1103029108.
The trace amine-associated receptor 1 (TAAR1), activated by endogenous metabolites of amino acids like the trace amines p-tyramine and β-phenylethylamine, has proven to be an important modulator of the dopaminergic system and is considered a promising target for the treatment of neuropsychiatric disorders. To decipher the brain functions of TAAR1, a selective TAAR1 agonist, RO5166017, was engineered. RO5166017 showed high affinity and potent functional activity at mouse, rat, cynomolgus monkey, and human TAAR1 stably expressed in HEK293 cells as well as high selectivity vs. other targets. In mouse brain slices, RO5166017 inhibited the firing frequency of dopaminergic and serotonergic neurons in regions where Taar1 is expressed (i.e., the ventral tegmental area and dorsal raphe nucleus, respectively). In contrast, RO5166017 did not change the firing frequency of noradrenergic neurons in the locus coeruleus, an area devoid of Taar1 expression. Furthermore, modulation of TAAR1 activity altered the desensitization rate and agonist potency at 5-HT(1A) receptors in the dorsal raphe, suggesting that TAAR1 modulates not only dopaminergic but also serotonergic neurotransmission. In WT but not Taar1(-/-) mice, RO5166017 prevented stress-induced hyperthermia and blocked dopamine-dependent hyperlocomotion in cocaine-treated and dopamine transporter knockout mice as well as hyperactivity induced by an NMDA antagonist. These results tie TAAR1 to the control of monoamine-driven behaviors and suggest anxiolytic- and antipsychotic-like properties for agonists such as RO5166017, opening treatment opportunities for psychiatric disorders.
TAAR1 agonists attenuate extended-access cocaine self-administration and yohimbine-induced reinstatement of cocaine-seeking
Br J Pharmacol 2020 Aug;177(15):3403-3414.PMID:32246467DOI:10.1111/bph.15061.
Background and purpose: The trace amine-associated receptor 1 (TAAR1) negatively modulates dopamine transmission. Our previous studies demonstrated that TAAR1 agonists attenuated cue- and drug-induced cocaine-seeking and increased the elasticity of the cocaine demand curve, in the short-access cocaine self-administration model. Compulsive use of cocaine, which is an essential criterion of cocaine use disorder, can be induced by extended access to cocaine self-administration. Experimental approach: To characterize the role of TAAR1 in compulsive cocaine use, we evaluated the effects of activation of TAAR1 on cocaine intake, cocaine binge and cue-induced cocaine-seeking using the extended-access cocaine self-administration model in adult male Sprague-Dawley rats. We also investigated the role of TAAR1 in stress-triggered cocaine relapse by using the α2 -adrenoceptor antagonist yohimbine-induced reinstatement of cocaine-seeking. Key results: The selective TAAR1 partial agonist RO5263397 attenuated cocaine intake and did not develop tolerance during the 10-day extended-access cocaine self-administration. RO5263397 reduced a 12-h binge intake of cocaine after forced abstinence. RO5263397 also decreased cue-induced cocaine-seeking after prolonged abstinence from extended-access cocaine self-administration. Furthermore, RO5263397 and the selective TAAR1 full agonist RO5166017 reduced yohimbine-induced reinstatement of cocaine-seeking behaviour. Conclusion and implications: Activation of TAAR1 attenuated extended-access cocaine self-administration and stress-induced cocaine reinstatement. These results suggest that TAAR1 agonists are promising pharmacological interventions to treat cocaine use disorder and relapse.
