Chemistry:2,3,5-Trimethoxyamphetamine

From HandWiki

2,3,5-Trimethoxyamphetamine (2,3,5-TMA), also known as TMA-4, is a psychedelic drug of the phenethylamine and amphetamine families.[1][2] It is one of the possible positional isomers of trimethoxyamphetamine and is a positional isomer of 3,4,5-trimethoxyamphetamine (TMA or TMA-1).[1][2]

Use and effects

In his book PiHKAL (Phenethylamines I Have Known and Loved) and other publications, Alexander Shulgin lists 2,3,5-TMA's dose as greater than 80 mg orally and its duration as perhaps or about 6 hours.[1][3][4] Based on limited testing, it produced threshold effects including much introspection among others, along with no subjective physical symptoms.[1][2] The drug at 80 mg was described as comparable to 50 μg LSD or 120 mg TMA and as being roughly 4-fold as potent as mescaline.[1][2] Per Shulgin, more testing is needed to fully characterize the drug in humans.[1]

Interactions

Pharmacology

Pharmacodynamics

2,3,5-TMA shows affinity for serotonin receptors.[2][5][6] The drug substitutes for DOM in rodent drug discrimination tests.[2][7]

Chemistry

Synthesis

The chemical synthesis of 2,3,5-TMA has been described.[1][2]

History

2,3,5-TMA was first described in the scientific literature by Alexander Shulgin in 1966.[8] Subsequently, it was described in greater detail by Shulgin in his 1991 book PiHKAL (Phenethylamines I Have Known and Loved).[1]

Society and culture

Canada

2,3,5-TMA is a controlled substance in Canada under phenethylamine blanket-ban language.[9]

United States

As a positional isomer of 3,4,5-trimethoxyamphetamine (TMA), 2,3,5-TMA is a Schedule I controlled substance in the United States.[2]
