Chemical compound
3,4-Dimethoxyphenethylamine (DMPEA ), also known as O ,O -dimethyldopamine , is a chemical compound of the phenethylamine class. It is an analogue of the major human neurotransmitter dopamine where the 3- and 4-position hydroxy groups have been replaced with methoxy groups. It is also closely related to mescaline which is 3,4,5-trimethoxyphenethylamine and to 3,4-dimethoxyamphetamine (3,4-DMA).
DMPEA shows weak affinity for serotonin receptors .[ 1] It induces the head-twitch response , a behavioral proxy of serotonergic psychedelic effects, in rodents.[ 2] However, according to Alexander Shulgin , it was inactive in humans at doses of 1,000 mg orally and 10 mg intravenously .[ 3]
DMPEA has some activity as a monoamine oxidase inhibitor .[ 4]
One of the earliest syntheses of DMPEA (then referred to as "homoveratrylamine") was that of Pictet and Finkelstein, who made it in a multi-step sequence starting from vanillin .[ 5] A similar sequence was subsequently reported by Buck and Perkin,[ 6] as follows:
3,4-Dimethoxybenzaldehyde (veratraldehyde) → 3,4-Dimethoxycinnamic acid → 3,4-Dimethoxyphenylpropionic acid → 3,4-Dimethoxyphenylpropionamide → 3,4-Dimethoxyphenethylamine
A much shorter synthesis is given by Shulgin and Shulgin:[ 7] [ 8]
A known use was in the synthesis of bevantolol .
DMPEA occurs naturally along with mescaline in various species of cacti such as San Pedro and Peruvian Torch .[ 9] [ 10] [ 11]
