Metabolite Identification
Common Name3,4-Dimethoxyphenylethylamine
Description3,4-Dimethoxyphenylethylamine, also known as 3,4-DMPEA or DMPEA is an endogenous metabolite found in urine that belongs to both the phenethylamine and catecholamine families. DMPEA is an analogue of dopamine (3,4-dihydroxyphenethylamine), with a substitution of the hydroxy groups with methoxy groups. DMPEA is also structurally similar to mescaline (3,4,5-trimethoxyphenylethylamine) and occurs naturally alongside it in various species of cacti such as the San Pedro and Peruvian Torch (PMID: 5511715 , 925910 , 600028 ). DMPEA received wide attention after it was proposed as a biomarker in schizophrenic patients urine, however later studies revealed that DMPEA is also excreted by non-schizophrenics (PMID: 709888 ). DMPEA has little known bioactivity, but it has some action as a monoamine oxidase inhibitor (PMID: 886445 ). DMPEA has also been shown to have neurotoxic effects, especially in the nigrostriatal system and among dopaminergic neurons (PMID: 9409711 , 9134983 ). DMPEA appears to be an inhibitor of mitochondrial complex I (PMID: 9409711 ).
