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
Hallucinogenic fish that makes dreams" in Arabic. Other species claimed to be capable of producing hallucinations include several species of sea chub from the genus "Kyphosus". It is unclear whether the toxins are produced by the fish themselves or by marine algae in their diet. Other hallucinogenic fish are "Siganus spinus", called "the fish that inebriates" in Reunion Island, and "Mulloidichthys flavolineatus" (formerly "Mulloidichthys samoensis"), called "the chief of ghosts" in Hawaii. The active agent(s) that cause hallucinations in humans, and the origin of these agents, are not clear. Some authors think they could come from toxins associated with macroalgae that accumulate
