5-MeO-DMT (5-methoxy-N,N-dimethyltryptamine), also known as O-methylbufotenin or mebufotenin (INNTooltip International Nonproprietary Name), is a naturally occurring psychedelic of the tryptamine family.[5][1][4][2] It is found in a wide variety of plant species, and is also secreted by the glands of at least one toad species, the Colorado River toad.[5] It may occur naturally in humans as well.[5] Like its close relatives dimethyltryptamine (DMT) and bufotenin (5-HO-DMT), it has been used as an entheogen in South America.[5][6] Slang terms include Five-methoxy, the power, bufo, and toad venom.[7]

The drug acts as a non-selective serotonin receptor agonist, including of the serotonin 5-HT1A and 5-HT2A receptors among others.[1][4][8] However, 5-MeO-DMT differs from most other serotonergic psychedelics in having 100- to 1,000-fold higher affinity for the serotonin 5-HT1A receptor over the serotonin 5-HT2A receptor.[1][4][8] In relation to this, 5-MeO-DMT has been described as an "atypical" psychedelic and as producing subjective effects notably distinct from those of DMT and other psychedelics, for instance having a relative lack of visual effects.[5][1][4] Like DMT, 5-MeO-DMT has a very rapid onset of action and short duration.[1][4] However, 5-MeO-DMT is 4- to 10-fold more potent than DMT in humans.[2]

5-MeO-DMT was first synthesized in 1936 and was first isolated from a natural source in 1959.[5] It is a controlled substance in some countries, for instance the United States, United Kingdom, Australia, and New Zealand.[5] The drug is used recreationally and several deaths have been reported in association with its use.[5][9] 5-MeO-DMT is being developed for potential use in medicine in the treatment of neuropsychiatric disorders such as depression.[5][1][4]

Chemistry

[edit]

5-MeO-DMT, also known as 5-methoxy-N,N-dimethyltryptamine, is a substituted tryptamine derivative. It is the 5-methoxylated derivative of N,N-dimethyltryptamine (DMT), the N,N-dimethylated derivative of 5-methoxytryptamine (5-MT; mexamine), and the O-methylated derivative of bufotenin (5-HO-DMT).

It has a relatively high experimental log P of 3.30.[2][10]

Analogues of 5-MeO-DMT include 4-MeO-DMT, 5-MeO-AMT, 5-MeO-DET, 5-MeO-DPT, 5-MeO-DIPT, 5-MeO-MiPT, 5-EtO-DMT, and 5-MeO-MET. Other analogues include dimemebfe and EMDT.

Effects

[edit]

When smoked, the duration of effects can be as little as ten minutes; when insufflated, up to two hours. Effects vary and can range from radical perspective shifting and perception of new insights, euphoria, immersive experiences, dissociation and non-responsiveness, sensual/erotic enhancement, to dysphoria, fear, terror, panic, and ego death.[11][better source needed]

The subjective effects of 5-MeO-DMT are described as distinct from those of DMT and other psychedelics.[4][5] Whereas DMT is described as producing more "information-rich" experiences, with "rich sensory phenomenology", visuals, and experiences of encountering entities and visiting other worlds, 5-MeO-DMT is described as having a relative lack of visual effects, producing a sense of "nothingness", and causing experiences that are said to be "content-free" and sometimes known as "whiteouts".[4][5] These experiences have been described as "beyond ordinary human comprehension", with a subjective impression of a void or amnesia of the experience.[4][5] In spite of this however, some have described the experiences as orgasmic, ecstatic, and blissful, whereas others have described them as terror or "information overwhelm".[4] As with DMT and other psychedelics, the experiences with 5-MeO-DMT are often described as overwhelming, profound, spiritual, religious, and/or mystical.[4][5]

The experiences of 5-MeO-DMT have been related to the experience of ecstatic seizures.[4]

Uses

[edit]

Preliminary clinical findings suggest that 5-MeO-DMT might have antidepressant and anxiolytic effects.[12][13]

Religious use

[edit]

The Church of the Tree of Life, founded in California in 1971 by John Mann but now defunct, declared the use of 5-MeO-DMT to be a sacrament. From approximately 1971 to the late 1980s, 5-MeO-DMT was discreetly available to its members.[14][15] Between 1970 and 1990, smoking of 5-MeO-DMT on parsley was probably one of the two most common forms of ingestion in the United States.[15][unreliable source?]

5-MeO-DMT is a methoxylated derivative of dimethyltryptamine (DMT). While most common psychedelics are believed to primarily elicit psychological effects through agonism of serotonin 5-HT2A receptors, 5-MeO-DMT shows 1,000-fold greater affinity for 5-HT1A over 5-HT2A;[24] In line with its affinity for 5-HT1A receptors, 5-MeO-DMT is extremely potent at suppressing the firing of dorsal raphe 5-HT neurons.[25] Further, its activity in rats was attenuated with the 5-HT1A selective antagonist WAY-100635 while 5-HT2A selective antagonist volinanserin failed to demonstrate any change.[26] Additional mechanisms of action such as inhibition of monoamine reuptake may be involved.[27] A 2019 European study with 42 volunteers showed that a single inhalation produced sustained enhancement of satisfaction with life, and easing of anxiety, depression, and post-traumatic stress disorder (PTSD).[28] A 2018 study demonstrated that a single dose of 5-MeO-DMT induced neurogenesis in mice.[29]

Similarly to other serotonergic psychedelics, 5-MeO-DMT is a non-selective serotonin receptor agonist, including of the serotonin 5-HT1A, 5-HT2A, 5-HT2B, and 5-HT2C receptors, among others.[1][4][21][20] It is 4- to 10-fold more potent as a hallucinogen than DMT in humans.[2] In contrast to most serotonergic psychedelics however, it is has been said that it is unclear that the hallucinogenic effects of 5-MeO-DMT are principally mediated by activation of the serotonin 5-HT2A receptor.[4] In any case, 5-MeO-DMT does still activate the serotonin 5-HT2A receptor and does still produce psychedelic effects.[4] It has been proposed that 5-MeO-DMT be considered an "atypical" psychedelic.[4] This relates to the fact that 5-MeO-DMT has 100- to 1,000-fold selectivity for the serotonin 5-HT1A receptor over the serotonin 5-HT2A receptor and that the actions of 5-MeO-DMT appear to be primarily mediated by serotonin 5-HT1A receptor activation.[1][4][2][8] For example, the potencies of drugs substituting for 5-MeO-DMT in drug discrimination assays is well-correlated with their serotonin 5-HT1A receptor affinities, and the discriminative stimulus effects of 5-MeO-DMT are attenuated by serotonin 5-HT1A receptor antagonists.[2] However, there is partial generalization of 5-MeO-DMT to the selective serotonin 5-HT2 receptor agonist (–)-DOM in animals.[2] In accordance with the preceding findings, 5-MeO-DMT is reported to produce notably distinct subjective effects compared DMT and other psychedelics in humans.[4]

Although 5-MeO-DMT shows dramatically higher affinity for the serotonin 5-HT1A receptor than for the serotonin 5-HT2A receptor, the situation appears to be very different in terms of its actual activational potencies at these receptors.[30][20][17] Its EC50Tooltip half-maximal effective concentration values have been found to be 1.80 to 3.87 nM at the serotonin 5-HT2A receptor and 3.92 to 1,060 nM at the serotonin 5-HT1A receptor.[30][20][17][23] For comparison, the EC50 values of DMT were found to be 38.3 nM at the serotonin 5-HT2A receptor and >10,000 nM at the serotonin 5-HT1A receptor in one of the same studies.[30][20] Hence, 5-MeO-DMT appears to be similarly potent or as much as 200-fold more potent as an agonist of the serotonin 5-HT2A receptor than of the serotonin 5-HT1A receptor.[30][20][17] In addition, 5-MeO-DMT is 10-fold more potent than DMT as an agonist of the serotonin 5-HT2A receptor.[30][20]

Besides the serotonin receptors, 5-MeO-DMT is an agonist of the melatonin MT1 and MT2 receptors.[19][23][22] Unlike DMT, 5-MeO-DMT is not a ligand or agonist of the sigma receptors.[5][23][22] In contrast to certain other tryptamines, 5-MeO-DMT is inactive as a monoamine releasing agent, including of serotonin, norepinephrine, and dopamine.[20] However, it is a weak serotonin reuptake inhibitor, with an IC50Tooltip half-maximal inhibitory concentration value of 2,184 nM.[20] Conversely, it is inactive as a dopamine and norepinephrine reuptake inhibitor (IC50 = >10,000 nM).[20]

Similarly to DMT, but in contrast to most other psychedelics, like LSD and psilocybin,[31][32] there appears to be very little development of tolerance with 5-MeO-DMT.[5][20][1][4] In fact, there may even be sensitization to the effects of 5-MeO-DMT.[4] The lack of tolerance development with 5-MeO-DMT may be due to biased agonism of the serotonin 5-HT2A receptor.[5] More specifically, 5-MeO-DMT activates the Gq signaling pathway of the serotonin 5-HT2A receptor with much less potency in recruiting β-arrestin2.[5][20] Activation of β-arrestin2 is linked to receptor downregulation and tachyphylaxis.[32][33][34]

Pharmacokinetics

[edit]

5-MeO-DMT is lipophilic and is thought to easily cross the blood–brain barrier.[2] Accordingly, 5-MeO-DMT readily accumulates in the brain in animals with levels higher than in blood.[2] This is in notable contrast to bufotenin (5-HO-DMT or N,N-dimethylserotonin) and serotonin (5-HT), which are hydrophilic and peripherally selective.[2][35][10]

Bufotenin is an active metabolite of 5-MeO-DMT, formed by O-demethylation by cytochrome P450 CYP2D6.[2] Bufotenin notably has much higher affinity for the serotonin 5-HT2A receptor than 5-MeO-DMT itself.[2] However, bufotenin does not seem to be extensively produced from 5-MeO-DMT in the brain.[2] In addition, peripherally formed bufotenin may not be able to exert significant central effects due to its limited ability to cross into the brain.[2] Hence, the involvement of bufotenin in the psychoactive effects of 5-MeO-DMT is uncertain.[2]

The metabolism of 5-MeO-DMT can be dramatically reduced and its levels markedly augmented and prolonged by monoamine oxidase inhibitors (MAOIs).[2] In addition, MAOIs allow 5-MeO-DMT to become orally active in humans.[2] Combination of 5-MeO-DMT with MAOIs has sometimes resulted in serotonin syndrome and death in humans.[2]

The Colorado River toad is a noted animal source of 5-MeO-DMT. First described in 1983 by Ken Nelson (writing under the pseudonym of Albert Most), smoking the parotoid secretions of the animal produces a powerful and short-lived psychedelic experience.[44] The smoking of I. alvarius secretions should not be confused with the urban legend of toad licking.[45] Since 1983, the animal has since became a popular source of 5-MeO-DMT for recreational or spiritual purposes.[46] Unfortunately, this increased demand and use of the toads as a source of 5-MeO-DMT has put strain on their populations.[47] Concerned with the ecological impacts of the growing use of I. alvarius secretions as a source of 5-MeO-DMT, Ken Nelson would later advocate for the use of synthetic 5-MeO-DMT and conservation of the Colorado River Toad.[48]

Research

[edit]

5-MeO-DMT is being developed and evaluated for potential therapeutic effects in patients with treatment-resistant depression (TRD).[55] Biopharmaceutical company GH Research has sponsored a completed phase 1 study in healthy volunteers[56] and phase 1/2 study in TRD patients where 87.5% of patients with TRD were brought into remission on day 7 in the phase 2 part of the study.[57] GH Research is currently planning a phase 2b study in TRD patients and have received approval for studies in patients with bipolar II disorder and a current depressive episode and patients with postpartum depression.[58]

Beckley Psytech in collaboration with King's College London is evaluating the safety and tolerability of intranasal 5-MeO-DMT in healthy subjects, in a phase 1 study.[59][60] Beckley Psytech CEO Cosmo Feilding-Mellen sees a potential in the short-acting nature of 5-MeO-DMT compared to psilocybin: "Requiring one or two therapists to sit in a room with a single patient for the entire duration of an MDMA or psilocybin experience, which is essentially a whole working day, is probably going to be very resource-intensive and expensive. There is already a global shortage of psychotherapists, and this poses a potential bottleneck to patient access in the future."[61]
