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 in the flesh of the fish. Toxins from the green algae "Caulerpa prolifera" in the Mediterranean Sea appear to be implicated, as is the seagrass "Posidonia oceanica". When herbivores eat seagrass leaves they ingest algal epiphytes and toxic dinoflagellates that live on the seagrass leaves. The German anthropologist Christian Rätsch thinks that dreamfish might contain the hallucinogen DMT. Ichthyoallyeinotoxism, or hallucinogenic fish inebriation, is a clinical syndrome that refers to a hallucinogenic inebriation of a distressing nature that can arise from consuming hallucinogenic fish. It is characterised by "psychologic disturbances of hallucination and depression. Gastrointestinal disturbance may occur". "Ichthyoallyeinotoxism is
