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
Satyrium (plant) Satyrium (plant) Satyrium is a genus of orchids. The Kew plant list for 2010 listed 85 full species as accepted, ignoring synonyms, subspecies and hybrids etc. About ten were still unresolved at the time. Most of the species occur in sub-Saharan Africa and Madagascar. The ranges of four species extend to Asia, mainly in India and Sri Lanka. Hybridization occurs between several species, complicating molecular phylogenetic studies, especially those relying on mitochondrial and chloroplast DNA sequences. The genus most closely related to "Satyrium" is presumed to be "Pachites", which together with "Satyrium" makes up the subtribe Satyriinae of the Diseae.
