#115 MDPEA3,4-METHYLENEDIOXYPHENETHYLAMINE; HOMOPIPERONYLAMINE
|[3D .mol structure]
DOSAGE: greater than 300 mg.
QUALITATIVE COMMENTS: (with 200 mg) It was taken twice at different times in a dosage of 200 milligrams each time, without the slightest peripheral or central effects.
(with 300 mg) My tinnitus had disappeared. Probably nothing.
EXTENSIONS AND COMMENTARY: How strange. Even more than DMPEA, this cyclic analogue MDPEA is a potential prodrug to dopamine, and would be a prime candidate for central activity. So why is this drug not active? The usual reason advanced by the pharmacologists is that the body is full of potent enzymes known as monoamine oxidases, and this is a monoamine, and so the body simply chews away on it in an oxidative manner, inactivating it before it ever makes it to some target receptor.
That is the pitch given in the textbooks. Phenethylamines are subject to easy enzymatic oxidation, hence they are not active. The presence of an alpha-methyl group (the corresponding amphetamines) blocks the compound from easy access to the enzyme, and since that protects them from oxidative destruction, they are active. The oft-quoted exception is mescaline, and even it is largely destroyed, as evidenced by the large amount needed for activity (a fraction of a gram). Sorry, I can't buy it. This entire book is peppered with phenethylamines that are active at the few-milligram area. Why aren't they also destroyed as well? The textbooks simply are not right.
MDPEA was one of the seven compounds evaluated as to toxicity and animal behavior at the University of Michigan under contract from the Army Chemical Center. Its Edgewood Arsenal code number was EA-1297. The number for MDA itself was EA-1298.
The beta-hydroxy analogue of MDPEA is the ethanolamine MDE, standing for methylenedioxyethanolamine. This is an old term, and in the more recent literature, since 1975 certainly, MDE has been used to represent methylenedioxyethylamphetamine. The ethanolamine compound is discussed in the recipe for DME.
There is a family of compounds, to be discussed elsewhere, that is called the Muni-Metro (see under METHYL-J). The simplest member is this compound, MDPEA, and under its chemically acceptable synonym, homopiperonylamine, it can be called RHS. Following that code, then, the N-methyl homologue of MDPEA is METHYL-H, and it has been looked at, clinically, as an antitussive agent. N-METHYL-MDPEA, or METHYL-H, or N-methyl-3,4-methylenedioxyphenethylamine is effective in this role at dosages of about 30 milligrams, but I have read nothing that would suggest that there were any central effects. I have tried it at this level and have found a little tightness of the facial muscles, but there was nothing at all in the mental area.
