3-Methoxytyramine (3-MT), also known as 3-methoxy-4-hydroxyphenethylamine, is a human trace amine that occurs as a metabolite of the neurotransmitter dopamine.[1] It is formed by the introduction of a methyl group to dopamine by the enzyme catechol-O-methyl transferase (COMT). 3-MT can be further metabolized by the enzyme monoamine oxidase (MAO) to form homovanillic acid (HVA), which is then typically excreted in the urine.

Originally thought to be physiologically inactive, 3-MT has recently been shown to act as an agonist of human TAAR1.[1][2]

Occurrence

3-Methoxytyramine occurs naturally in the prickly pear cactus (genus Opuntia),[3] and is in general widespread throughout the Cactaceae.[4] It has also been found in crown gall tumors on Nicotiana sp.[5]

In humans, 3-methoxytyramine is a trace amine that occurs as a metabolite of dopamine.[1] Шаблон:Catecholamine and trace amine biosynthesisШаблон:Clear left
