6-MeO-DMT

6-MeO-DMT, or 6-methoxy-N,N-dimethyltryptamine, also known as 6-OMe-DMT, is a serotonergic drug of the tryptamine family.^[1][2][3] It is the 6-methoxy derivative of the serotonergic psychedelic N,N-dimethyltryptamine (DMT) and is a positional isomer of the psychedelic 5-MeO-DMT.^[3][4]

Similarly to analogues like DMT and 5-MeO-DMT, 6-MeO-DMT acts as a serotonin 5-HT_2A receptor agonist as well as a non-selective agonist of many other serotonin receptors.^[1][2][5][3] However, in contrast to these agents, but similarly to certain other serotonin 5-HT_2A receptor agonists like 6-fluoro-DET, 2-bromo-LSD, lisuride, 25N-N1-Nap, and tabernanthalog, 6-MeO-DMT does not produce the head-twitch response (HTR) or other psychedelic-like effects in animals and hence appears to be non-hallucinogenic.^[1][2][6][5] Similarly, 6-MeO-DMT failed to substitute for DOM in rodent drug discrimination tests.^[7] On the other hand, it did substitute for the atypical psychedelic 5-MeO-DMT in rodent drug discrimination tests, with about 4-fold lower potency than 5-MeO-DMT.^[8] 6-MeO-DMT has yet to be tested in humans.^[9][2]

In addition to its apparent lack of hallucinogenicity, 6-MeO-DMT shows dramatically reduced potency as an agonist of all of the serotonin receptors compared to 5-MeO-DMT.^[5] Its affinity for the serotonin 5-HT_2A receptor was 12- to 43-fold lower than that of 5-MeO-DMT and was 6-fold lower than that of DMT and its affinity for the serotonin 5-HT_1A receptor was 110-fold lower relative to 5-MeO-DMT.^[3][1][10]

6-MeO-DMT was first described in the scientific literature by 1968.^[11][12][13] It was specifically assessed in a structure–activity relationship (SAR) animal study of serotonergic tryptamines.^[11][12] The drug's lack of hallucinogen-like effects in animals was first described by at least 1983.^[7]
