描述
4-Methoxytyramine is a catecholamine derivative. Catecholamines are important components of the central nervous system. A number of diseases are characterized by abnormal levels of catecholamines. For example, patients with Parkinson's disease have lower levels of dopamine than normal. L-3,4-Dihydroxyphennylalanune (L-Dopa), a catechol a-amino acid, is widely used in the treatment of Parkinson's disease. When L-Dopa is given orally to patients, the most prominent metabolite is 3-methoxy-4-hydroxyphenylalanine. However, a part of L-Dopa is methylated to 3-hydroxy-4-methylphenylalanine and to 3-hydroxy-4-methoxyphenethylamine. It has been reported that 4-O-methylation of catecholamines is implicated in some neuropsychiatric disorders and thus 3-hydroxy-4-methoxyphenethylamine appears to be the endogenous "toxin" in Parkinson's disease. Consequently, the determination of plasma levels of 3-hydroxy-4-methoxyphenethylamine is important following oral L-Dopa therapy (PMID: 6518609). [HMDB]
