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
Glossary of leaf morphology be simple, with a single leaf blade, or compound, with several leaflets. In flowering plants, as well as the blade of the leaf, there may be a petiole and stipules; compound leaves may have a rachis supporting the leaflets. Leaf structure is described by several terms that include: Being one of the more visible features, leaf shape is commonly used for plant identification. Similar terms are used for other plant parts, such as petals, tepals, and bracts. Leaf margins (edges) are frequently used in visual plant identification because they are usually consistent within a species or group of species, and
