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 of nitrogen-containing natural products. Examples of psychoactive compounds of plant origin that do not contain nitrogen are tetrahydrocannabinol (a phytocannabinoid from "Cannabis sativa") and salvinorin A (a diterpenoid from "Salvia divinorum"). Psychoactive plant Psychoactive plants are plants, or preparations thereof, that upon ingestion induce psychotropic effects. As stated in a reference work: Psychoactivity may include sedative, stimulant, euphoric, deliriant, and hallucinogenic effects. Several hundred psychoactive plants are known. Some important examples of psychoactive plants include "Coffea arabica" (coffee), "Camellia sinensis" (tea), "Nicotiana tabacum" (tobacco), and "Cannabis" (including hashish). Psychoactive plants have been used ritually ("e.g.", peyote as an entheogen), medicinally
