Α,N,N-Trimethyltryptamine
Psychoactive drug
Psychoactive drug
α,N,N-Trimethyltryptamine (α,N,N-TMT, α-TMT, or ATMT), also known as α-methyl-N,N-dimethyltryptamine (α-methyl-DMT or α-Me-DMT) or as Alpha-N, is a psychedelic drug of the tryptamine and α-alkyltryptamine families. It is similar in chemical structure to other psychedelic tryptamines such as N,N-dimethyltryptamine (DMT) and α-methyltryptamine (αMT). It is taken orally.
Use and effects
α,N,N-TMT was briefly mentioned by Alexander Shulgin in his 1997 book TiHKAL (Tryptamines I Have Known and Loved), but he did not mention having tested it and did not describe its effects, dose, or duration. In 2025, Hamilton Morris described having synthesized and assayed α,N,N-TMT. He reported that it was an active psychedelic taken orally but was much less potent than AMT.
Interactions
Pharmacology
Pharmacodynamics
The drug has been tested in animals and compared with α-methyltryptamine (αMT). It was found to produce similar effects as αMT, such as hyperlocomotion and reversal of reserpine-induced behavioral depression, but with only around half the potency of αMT.
Chemistry
Analogues
Analogues of α,N,N-TMT (N,N-dimethyl-AMT) include α-methyltryptamine (AMT), α,N-DMT (N-methyl-AMT), α-methylserotonin (AMS; 5-HO-AMT), 5-MeO-AMT (α,O-DMS), α,N,O-TMS (N-methyl-5-MeO-AMT), and α,N,N,O-TeMS (N,N-dimethyl-5-MeO-AMT), among others.
History
α,N,N-TMT was encountered as a novel designer drug in Europe by 2015.
Society and culture
Legal status
