Substituted tryptamines, or simply tryptamines, also known as serotonin analogues (i.e., 5-hydroxytryptamine analogues), are organic compounds which may be thought of as being derived from tryptamine itself. The molecular structures of all tryptamines contain an indole ring system, joined to an amino (NH2) group via an ethyl (−CH2–CH2−) sidechain. In substituted tryptamines, the indole ring, sidechain, and/or amino group are modified by substituting another group for one of the hydrogen (H) atoms.
Well-known tryptamines include serotonin, an important neurotransmitter, and melatonin, a hormone involved in regulating the sleep-wake cycle. Tryptamine alkaloids are found in fungi, plants and animals; and sometimes used by humans for the neurological or psychotropic effects of the substance. Prominent examples of tryptamine alkaloids include psilocybin (from "psilocybin mushrooms") and DMT. In South America, dimethyltryptamine is obtained from numerous plant sources, like chacruna, and it is often used in ayahuasca brews. Many synthetic tryptamines have also been made, including the migraine drug sumatriptan, and psychedelic drugs. A 2022 study has found the variety of tryptamines present in wild mushrooms may affect the therapeutic impact. [1]
The tryptamine structure, in particular its indole ring, may be part of the structure of some more complex compounds, for example cyclized tryptamines like LSD, ibogaine, harmaline, mitragynine and yohimbine. A thorough investigation of dozens of tryptamine compounds was published by Alexander Shulgin and Ann Shulgin in 1997 under the title TiHKAL (Tryptamines I Have Known and Loved). [2]
The doses, potencies, durations, and effects of psychedelic tryptamines have been reviewed by Alexander Shulgin and other authors. [3] [4] [5] [6] [2] [7] [8] [9] [10] [11]

α-Alkyltryptamines are a group of substituted tryptamines which possess an alkyl group, such as a methyl or ethyl group, attached at the alpha carbon, and in most cases no substitution on the amine nitrogen. [51] [52] [53] α-Alkylation of tryptamine makes it much more metabolically stable and resistant to degradation by monoamine oxidase, resulting in increased potency and greatly lengthened half-life. [53] This is analogous to α-methylation of phenethylamine into amphetamine. [53]
Many α-alkyltryptamines are drugs, acting as monoamine releasing agents, non-selective serotonin receptor agonists, and/or monoamine oxidase inhibitors, [54] [55] [56] [57] and produce psychostimulant, entactogen, and/or psychedelic effects. [51] [52] [53] The most well-known of these agents are α-methyltryptamine (αMT) and α-ethyltryptamine (αET), both of which were used clinically as antidepressants for a brief period of time in the past and are abused as recreational drugs. [52] [53] In accordance with its action as a dual releasing agent of serotonin and dopamine, αET has been found to produce serotonergic neurotoxicity similarly to amphetamines like MDMA and PCA, and the same is also likely to hold true for other serotonin and dopamine-releasing α-alkyltryptamines such as αMT, 5-MeO-αMT, and various others.

A number of β-ketotryptamines (beta-ketotryptamines) are known. [63] [65] [68] These compounds are α-alkyl-β-ketotryptamines and are analogous to the cathinones (β-ketoamphetamines) of the related phenethylamine family. Known β-ketotryptamines include BK-NM-AMT, BK-5F-NM-AMT, BK-5Cl-NM-AMT, and BK-5Br-NM-AMT. [63] [65] [68] They act as monoamine releasing agents. [63] [65] [68]
Examples of cyclized tryptamines include:
Other closely related cyclized tryptamine-like compounds include the following:
A number of related compounds are known, with a similar structure but having the indole core flipped (isotryptamines) and/or replaced with related cores such as indene, indoline, indazole, indolizine, benzothiophene, or benzofuran. Like tryptamines, these related compounds are primarily active as agonists at the 5-HT2 family of serotonin receptors, with applications in the treatment of glaucoma, cluster headaches, or as anorectics.

{{cite conference}}: CS1 maint: bot: original URL status unknown (link)Doses for vaporized or inhaled free-base DMT are typically 40–50 mg, although larger doses have been reported (100 mg; Shulgin and Shulgin 1997). Pallavicini et al. (2021) have reported that vaporization of approximately 40 mg of DMT, administered in a natural setting, produced potential electroencephalographic markers of mystical-type experiences in 35 volunteers. The onset of effects for inhaled DMT is rapid, similar to that of IV administration, but lasts less than 30 min (Riba et al. 2015; Davis et al. 2020). [...] For administration of pharmahuasca, 50 mg DMT:100 mg harmaline is usually the recommended dosage. However, combinations of 50 mg harmaline:50 mg harmine and 50 mg DMT have been tested with success. The harmalas and DMT are typically put into separate gelatin capsules, with the harmaline/harmine being taken first and the DMT being taken 15 to 20 min later. The use of moclobemide, a reversible inhibitor of MAO-A, has also been reported in DMT "pharmahuasca" studies (Kaasik et al. 2020; Ruffell et al. 2020).
Recent studies tested i.v. DMT with different administration regimens. Such protocols entailed 0–19.2 mg bolus 0.5–0.8 mg/min constant infusion of DMT freebase (as hemifumarate) for up to 90 min (Basel) [7], 11.2 mg bolus 1.2 mg/min infusion of DMT freebase (as fumarate) for up to 30 min (London) [8], and constant infusion totaling 13.4 mg DMT freebase (as fumarate) over 10 min (London) [110]). [...] The various β-carbolines in B. caapi, especially harmine and harmaline, enable the attainment of sufficient plasma DMT concentrations to evoke psychedelic effects lasting 4–6 h [5, 61].
Since the β-carbolines per se could not explain the legendary psychoptic (visionary) activity of the jungle ambrosia, this had to be due to its DMT content, which amounted to an average of 29 mg/dose in the 16 potions analyzed (range: 25-36 mg/dose). [...] TABLE 1 Human Pharmacology of Psychoptic Tryptamines [...]
Other N,N-dialkyltryptamines produce similar effects to DMT in man, though their persistence is somewhat greater, with hallucinations lasting for up to 3 hours (Szara and Hearst, 1962). These include the N,N-diethyl (DET, 4.8), N,N-dipropyl (4.9), and N,N-diallyl (4.10) compounds, none of which are found in nature.
The dipropyl and diallyl derivatives have similar hallucinogenic activity in man, as we found recently.
Szara and co-workers (221,223,225) noted psychotomimetic activity for N,N-diethyltryptamine (DET; 38) at a dose of 1 mg/kg. [...] N,N-Dipropyltryptamine (DPT; 39) is also hallucinogenic in man at 1 mg/kg (222). [...] Branching of the propyl groups results in N,N-diisopropyltryptamine (DIPT; 40), which is orally active at 20 to 50 mg (202). N,N-Dibutyltryptamine (DBT; 41) and N,N-dihexyltryptamine (DHT; 42) have been examined only briefly. At 1 mg/kg, DBT produced only slight perceptual, emotional, and thinking disturbances in man, while DHT at the same dose was completely inactive (222).
4-OH-DPT is the 4-hydroxylated DPT derivative first synthesized by Shulgin et al. [82]. 4-OH-DPT is a light beige or white powder [54] that acts as a 5-HT2A partial agonist. 4-OH-DPT also shares structural similarity with psilocin [83]. Effects are dose dependent, with onset at 15–45 min and duration of 5–8 h. According to user reports, synthetic 4-OH-DPT produces visual effects and hallucinatory states [84].
[Morris:] Bufotenine is a drug that I have tried. I've tried isolated pure bufotenine and it is a psychedelic that is both pharmacologically and experientially and chemically intermediate between DMT and 5-MeO-DMT. So it has a longer duration than actually both 5-MeO-DMT and DMT. It's yet less visual than DMT but more visual than 5-MeO-DMT, so it's kind of like in-between the two. It's also very nauseating, which is the main reason that people seem not to enjoy it very much. But it is a classical psychedelic drug that produces visionary effects. And Jonathan Ott actually liked the effect of it quite a bit.
[Morris:] I've used [bufotenine] a couple times, once at 50 milligrams of the freebase snorted. [...] I found it to be extremely nauseating. I found it to be qualitatively intermediate between 5-MeO-DMT and DMT in that it was more visual than my experiences with 5-MeO-DMT but less visual than my typical experiences with DMT. It had a longer duration than 5-MeO-DMT and maybe even a longer duration than DMT as well. It was about an hour. Although I don't have all that much experience snorting DMT freebase.
[...] [Hartsel:] The α,N,N-Dimethyl[tryptamine]. [Morris:] Oh yeah, I've made it and tried it actually. [Hartsel:] Oh you did? [Morris:] Yeah, yeah. [Hartsel:] Oh, well what did it do? [Morris:] It is active, it's an active psychedelic. It's reduced potency. I never got it to a dose where it produced particularly interesting effects. I can look up the exact dose. I think it was like... the only thing I remember is that I felt like it was making me sneeze a lot. But it was very pleasant. Nothing bad happened. But the dose just wasn't high enough. I think I took maybe 40 mg. So it was much less potent than AMT orally. The other issue of course is that it could be a prodrug of N-methyl-AMT, which is active, or AMT itself maybe. [...]
