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
Psychoactive plant a few examples of significant psychoactive plants and their effects are shown. For further examples, see List of psychoactive plants. In the plant kingdom (Plantae), almost all psychoactive plants are found within the flowering plants (angiosperms). There are many examples of psychoactive fungi, but fungi are not part of the plant kingdom. Some important plant families containing psychoactive species are listed below. The listed species are examples only, and a family may contain more psychoactive species than listed. The active constituents of the majority of psychoactive plants fall within the alkaloids ("e.g.", nicotine, morphine, cocaine, mescaline, caffeine, ephedrine), a class
