5-MeO-NMT, also known as5-methoxy-N-methyltryptamine, is antryptaminealkaloid, being the 5-methoxyanalogue ofN-methyltryptamine (NMT). It was first isolated fromPhalaris arundinacea (reed canary grass) and also occurs in other species such asVirola species andBufo alvarius skin.[1][2] The compound has beensynthesized byAlexander Shulgin and reported in his bookTiHKAL (Tryptamines I Have Known and Loved).[1]

Use and effects

[edit]

Alexander Shulgin included 5-MeO-NMT as an entry in his bookTiHKAL (Tryptamines I Have Known and Loved).[1] However, he does not appear to have tried it and states that thedose andduration of the compound are unknown.[1] In any case, Shulgin stated that it would be expected to be rapidlymetabolized bymonoamine oxidase and that it would likely only be activeparenterally.[1]

5-MeO-NMT is apotentagonist of theserotonin5-HT1A,5-HT2A,5-HT2B, and5-HT2C receptors.[4] It is afull agonist or near-full agonist of all of these receptors except for the serotonin 5-HT1A receptor, where it is apartial agonist.[4] It additionally displays a high affinity for multiple otherserotonin receptors.[4] The drug is also a very weakserotonin releasing agent and has sub micromolar affinity fordopamine D4 receptor.[3][4]

5-MeO-NMT does not produce thehead-twitch response, a behavioral proxy ofpsychedelic effects, in rodents, and in some cases even reduced total HTRs.[4] On the other hand, it does induce serotonin 5-HT1A receptor-mediatedhypothermia andhypolocomotion.[4] Earlier reports had stated that 5-MeO-NMT and itsN-demethylated analogue5-methoxytryptamine were inactive, but this proved not to be the case.[5]
