3-methoxy Tyramine (hydrochloride)

3-methoxy Tyramine (hydrochloride) (CAS No.: 1477-68-5) is an endogenous metabolite of dopamine generated through catechol O-methyltransferase-mediated metabolism and is widely utilized as a biochemical tool in neuropharmacology and neurotransmitter research. Functionally, it acts as a trace amine-associated receptor 1 (TAAR1) agonist with activity in the low micromolar range, thereby modulating intracellular signaling pathways that influence monoaminergic neurotransmission and neuronal excitability. Although considered a relatively weak agonist, its ability to regulate dopamine-related signaling cascades makes it valuable for investigating receptor-ligand interactions, neuromodulatory mechanisms, and synaptic transmission dynamics. In addition to its role in receptor pharmacology, 3-methoxy Tyramine serves as a biomarker for catecholamine metabolism, with its levels commonly monitored to assess COMT activity in neurological disorders such as Parkinson’s disease, and to evaluate dysregulated catecholamine biosynthesis observed in certain neuroendocrine tumors. In experimental settings, this compound is frequently applied in cell-based assays and animal models to study TAAR1-mediated pathways, neurotransmitter release, and dopaminergic system function, with concentrations or dosing regimens adjusted according to specific experimental designs and research objectives in drug discovery and neuroscience research.
