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
Passerina (plant) endemic to Southern Africa, most species within South Africa, though some extend north of the border. The greatest concentration of species is in Cape fynbos, where some species are endemic to very small regions. "Passerina ericoides" for example occurs naturally only on the Cape Peninsula and the vicinity of False Bay There are some 20 accepted species in the genus "Passerina" plus about sixty unresolved and over 100 synonyms. The following are the accepted species, omitting subspecies. "Passerina" is a generally insignificant genus, seldom noticed by the non-botanist. The attractive ericoid habit and fuss-free growth make it a useful subject
