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
Stapelia hirsuta Stapelia hirsuta Stapelia hirsuta, common name starfish flower or carrion plant, is a species of flowering plant belonging to the family Apocynaceae. The genus epithet "Stapelia" was named in honour of Johannes van Stapel, who described the first plant discovered, while the species name derives from the Latin “hirsutus”, meaning "hairy”. "Stapelia hirsuta" stems are subquadrangular and about high. Concave groves run vertically along the stems, between their four angles. This feature distinguishes "S. hirsuta" from many other "Stapelia" species with which it naturally co-occurs (e.g. "Stapelia rufa", "Stapelia engleriana"), and which typically have stems which are also subquadrangular, but
