3-Methoxytyramine (3-MT), also known as 3-methoxy-4-hydroxyphenethylamine, is a metabolite of the neurotransmitter dopamine 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.
3-Methoxytyramine occurs naturally in the prickly pear cactus (genus Opuntia), and is in general widespread throughout the Cactaceae. It has also been found in crown gall tumors on Nicotiana sp.
