5-MeO-NMT, also known as 5-methoxy-N-methyltryptamine, is an tryptamine alkaloid, being the 5-methoxy analogue of N-methyltryptamine (NMT). It was first isolated from Phalaris arundinacea (reed canary grass) and also occurs in other species such as Virola species and Bufo alvarius skin.[1][2] The compound has been synthesized by Alexander Shulgin and reported in his book TiHKAL (Tryptamines I Have Known and Loved).[1]

Use and effects

Shulgin included 5-MeO-NMT as an entry in TiHKAL.[1] However, he does not appear to have tried it and states that the dosage and duration of the compound are unknown.[1] In any case, Shulgin stated that it would be expected to be rapidly metabolized by monoamine oxidase and that it would likely only be active parenterally.[1]

Pharmacology

Pharmacodynamics

5-MeO-NMT is a potent agonist of the serotonin 5-HT1A, 5-HT2A, 5-HT2B, and 5-HT2C receptors.[3] It is a full agonist or near-full agonist of all of these receptors except for the serotonin 5-HT2A receptor, where it is a partial agonist.[3] The drug is also a very weak serotonin releasing agent.[3][4]

5-MeO-NMT does not produce the head-twitch response, a behavioral proxy of psychedelic effects, in rodents.[3] On the other hand, it does induce serotonin 5-HT1A receptor-mediated hypothermia and hypolocomotion.[3] Earlier reports had stated that 5-MeO-NMT and its N-demethylated analogue 5-methoxytryptamine were inactive, but this proved not to be the case.[5]

Chemistry

Synthesis

The chemical synthesis of 5-MeO-NMT has been descibed.[1]

Analogues

Notable analogues of 5-MeO-NMT include NMT, 5-MeO-NET, 5-MeO-NiPT, norpsilocin (4-HO-NMT), baeocystin (4-PO-NMT), 4-HO-NALT, and 5-MeO-NBpBrT, among others.[3][4][1] 5-MeO-NMT is the N-monodemethylated analogue of 5-MeO-DMT.[1]

OL 4850660M. The same relationship holds with the 5-methoxy derivatives, the N-methyl compound and the parent tryptamine being metabolized by amine oxidases to an extent greater than 80 per cent (Kveder and Mcisaac, 1961; Taborsky and Mcisaac, 1964a) and being ineffective in altering animal behaviour (Smythies, Bradley, and Johnston, 1967), while 5-methoxy-N,N-dimethyltryptamine is resistant to oxidative deamination and is among the most potent of the hallucinogenic tryptamines.
