3,4-Dimethoxyphenethylamine synthesis of Bevantolol. DMPEA has some activity as a monoamine oxidase inhibitor. DMPEA occurs naturally along with mescaline in various species of cacti such as San Pedro and Peruvian Torch. 3,4-Dimethoxyphenethylamine 3,4-Dimethoxyphenethylamine (DMPEA) 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. 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
Isoproscaline mechanism of action shared by all of the hallucinogenic tryptamines and phenethylamines. The toxicity of isoproscaline is not known. Isoproscaline is unscheduled and unregulated in the United States, however because of its close similarity in structure and effects to mescaline, possession and sale of isoproscaline may be subject to prosecution under the Federal Analog Act. In the UK its highly likely that this compound would be covered by the "phenylethylamine amendment" to the misuse of drugs act likely rendering it (probably) a Class A controlled drug. Isoproscaline Isoproscaline or 4-(i)-propoxy-3,5-dimethoxyphenethylamine is an analogue of mescaline. It is closely related to
