Chemical compound

Trimethoxyamphetamines (TMAs) are a family ofpositionally isomeric psychedelic hallucinogenic drugs.^[1]^[2] There exist six different TMAs that differ only in the positions of the threemethoxy groups:TMA (TMA-1),TMA-2, TMA-3, TMA-4, TMA-5, andTMA-6.^[1]^[2] The TMAs aresubstituted amphetamines and areanalogues of thephenethylamine cactus alkaloid mescaline and theDOx drugs.^[1]^[2]

Themechanism of action of the TMAs is different from that of the unsubstituted compoundamphetamine, probably involvingagonist activity onserotonin receptors such as the5-HT_2A receptors instead of themonoamine releasing agent actions typical of most amphetamines. This action on serotonergic receptors likely underlies the psychedelic effects of these compounds.

TMA was firstsynthesized by Hey, in 1947.^[3] Synthesis data as well ashuman activity data has been published byAlexander Shulgin in his bookPiHKAL.^[1]^[2]

The most important TMA compound from a pharmacological standpoint is TMA-2, as this isomer has been much more widely used as arecreational drug and sold on thegrey market as a so-calledresearch chemical; TMA (sometimes referred to as "mescalamphetamine" or TMA-1) and TMA-6 have also been used in this way to a lesser extent. These three isomers are significantly more active as hallucinogenic drugs, and have consequently been placed onto the illegal drug schedules in some countries such as theNetherlands andJapan. The other three isomers TMA-3, TMA-4, and TMA-5 are not known to have been used as recreational drugs to any great extent. According to Shulgin, at the doses tested, TMA-3 was completely inactive, whereas TMA-4 and TMA-5 were said to produce effects comparable tolysergic acid diethylamide (LSD).^[1]

2,4,6-TMA (TMA-6) is apotent monoamine oxidase A (MAO-A)inhibitor, with an IC₅₀Tooltip half-maximal inhibitory concentration of 400 nM.^[4] Conversely, 2,4,5-TMA (TMA-2) and 3,4,5-TMA (TMA-1) are inactive as MAO-A inhibitors (IC₅₀ = >100,000 nM).[4] Other 6-substituted amphetamines also tend to be potent MAO-A inhibitors.^[4]
