5-Nitro-DMT (5-nitro-N,N-dimethyltryptamine) is a substituted tryptamine derivative which acts as a serotonin receptor agonist, [1] though its subtype selectivity has not been studied with modern techniques.
N,N-Dimethyltryptamine is a substituted tryptamine that occurs in many plants and animals, including humans, and which is both a derivative and a structural analog of tryptamine. DMT is used as a psychedelic drug and prepared by various cultures for ritual purposes as an entheogen.
5-MeO-DMT (5-methoxy-N,N-dimethyltryptamine) or O-methyl-bufotenin is a psychedelic of the tryptamine class. It is found in a wide variety of plant species, and also is secreted by the glands of at least one toad species, the Colorado River toad. Like its close relatives DMT and bufotenin (5-HO-DMT), it has been used as an entheogen in South America. Slang terms include Five-methoxy, the power, bufo, and toad venom.
Psilocin is a substituted tryptamine alkaloid and a serotonergic psychedelic substance. It is present in most psychedelic mushrooms together with its phosphorylated counterpart psilocybin. Psilocin is a Schedule I drug under the Convention on Psychotropic Substances. Acting on the 5-HT2A receptors, psilocin modulates the production and reuptake of serotonin. The mind-altering effects of psilocin are highly variable and subjective and resemble those of LSD and DMT.
DET, also known under its chemical name N,N-diethyltryptamine and as T-9, is a psychedelic drug closely related to DMT and 4-HO-DET. However, despite its structural similarity to DMT, its activity is induced by an oral dose of around 50–100 mg, without the aid of MAO inhibitors, and the effects last for about 2–4 hours.
5,N,N-trimethyltryptamine is a tryptamine derivative that is a psychedelic drug. It was first made in 1958 by Edwin H. P. Young. In animal experiments it was found to be in between DMT and 5-MeO-DMT in potency which would suggest an active dosage for humans in the 20–60 mg range. Human psychoactivity for this compound has been claimed in reports on websites such as Erowid but has not been independently confirmed.
5-Bromo-DMT (5-bromo-N,N-dimethyltryptamine) is a psychedelic brominated indole alkaloid found in the sponges Smenospongia aurea and Smenospongia echina, as well as in Verongula rigida alongside 5,6-Dibromo-DMT and seven other alkaloids. It is the 5-bromo derivative of DMT, a psychedelic found in many plants and animals.
5-MeS-DMT (5-methylthio-N,N-dimethyltryptamine) is a lesser-known psychedelic drug. It is the 5-methylthio analog of dimethyltryptamine (DMT). 5-MeS-DMT was first synthesized by Alexander Shulgin. In his book TiHKAL, the minimum dosage is listed as 15-30 mg. The duration listed as very short, just like DMT. 5-MeS-DMT produces similar effects to DMT, but weaker. Shulgin describes his feelings while on a low dose of this drug as "pointlessly stoned", although at a higher dose of 20 mg he says it is "quite intense" and suggests that a higher dose still might have full activity.
Dimemebfe (5-MeO-BFE) is a recreational drug and research chemical. It acts as an agonist for the 5-HT1A and 5-HT2 family of serotonin receptors. It is related in structure to the psychedelic tryptamine derivative 5-MeO-DMT, but with the indole nitrogen replaced by oxygen, making dimemebfe a benzofuran derivative. It is several times less potent as a serotonin agonist than 5-MeO-DMT and with relatively more activity at 5-HT1A, but still shows strongest effects at the 5-HT2 family of receptors.
5-Methoxy-7,N,N-trimethyltryptamine (5-MeO-7,N,N-TMT, 5-MeO-7-TMT), is a tryptamine derivative which acts as a partial agonist at the 5-HT2 serotonin receptors, with an EC50 of 63.9 nM and an efficacy of 66.2% at 5-HT2A (vs 5-HT), and weaker activity at 5-HT2B and 5-HT2C. In animal tests, both 7,N,N-TMT and 5-MeO-7,N,N-TMT produced behavioural responses similar to those of psychedelic drugs such as DMT and 5-MeO-DMT, but compounds with larger 7-position substituents such as 7-ethyl-DMT and 7-bromo-DMT did not produce psychedelic-appropriate responding despite high 5-HT2 receptor binding affinity, suggesting these may be antagonists or weak partial agonists for the 5-HT2 receptors. The related compound 7-MeO-MiPT (cf. 5-MeO-MiPT) was also found to be inactive, suggesting that the 7-position has poor tolerance for bulky groups at this position, at least if agonist activity is desired.
7,N,N-trimethyltryptamine (7-methyl-DMT, 7-TMT), is a tryptamine derivative which acts as an agonist of 5-HT2 receptors. In animal tests, both 7-TMT and its 5-methoxy derivative 5-MeO-7-TMT produced behavioural responses similar to those of psychedelic drugs such as DMT, but the larger 7-ethyl and 7-bromo derivatives of DMT did not produce psychedelic responses despite having higher 5-HT2 receptor affinity in vitro (cf. DOBU, DOAM). 7-TMT also weakly inhibits reuptake of serotonin but with little effect on dopamine or noradrenaline reuptake.
4-MeO-DMT (4-methoxy-N,N-dimethyltryptamine) is a tryptamine derivative which has some central activity in animal tests similar to that of related psychedelic tryptamine drugs, although with significantly lower potency than either 5-MeO-DMT or 4-hydroxy-DMT (psilocin).
4-Fluoro-5-Methoxy-N,N-dimethyltryptamine (4-F-5-MeO-DMT) was first described by David E. Nichols team in 2000. It is a potent 5-HT1A agonist. Substitution with the 4-fluorine markedly increased 5-HT1A selectivity over 5-HT2A/2C receptors with potency greater than that of the 5-HT1A agonist 8-OH-DPAT.
5-Ethyl-N,N-dimethyltryptamine is a tryptamine derivative which acts as an agonist at the 5-HT1A and 5-HT1D serotonin receptors, with around 3x selectivity for 5-HT1D.
5-(Nonyloxy)tryptamine is a tryptamine derivative which acts as a selective agonist at the 5-HT1B receptor. Increasing the O-alkoxy chain length in this series gives generally increasing potency and selectivity for 5-HT1B, with highest activity found for the nonyloxy derivative, having a 5-HT1B binding affinity of 1.0 nM, and around 300-fold selectivity over the related 5-HT1A receptor.
1-(2-Dimethylaminoethyl)dihydropyrano(3,2-e)indole (4,5-DHP-DMT) is a tricyclic tryptamine derivative which acts as a potent and reasonably selective partial agonist for the serotonin receptor 5-HT2A, with a Ki of 17.0 nM, and moderate selectivity over related serotonin receptors. It has lower 5-HT2 affinity and efficacy than the related compound AL-37350A, but higher lipophilicity.
Substituted tryptamines, or serotonin 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, 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.
4-Propionoxy-N,N-dimethyltryptamine is a synthetic psychedelic drug from the tryptamine family with psychedelic effects, and is believed to act as a prodrug for psilocin. It produces a head-twitch response in mice. It has been sold online as a designer drug since May 2019. It was first identified as a new psychoactive substance in Sweden, in July 2019. A number of related derivatives have been synthesised as prodrugs of psilocin for medical applications.
O-Acetylbufotenine is a tryptamine derivative which produces psychedelic-appropriate responding in animal studies. It is an acylated derivative of bufotenine with higher lipophilicity that allows it to cross the blood–brain barrier; once inside the brain, it is metabolised to bufotenine. It also acts directly as an agonist at 5-HT1A and 5-HT1D receptors.
5-Chloro-N,N-dimethyltryptamine (5-chloro-DMT) is a tryptamine derivative related to compounds such as 5-bromo-DMT and 5-fluoro-DMT. It acts as a serotonin receptor agonist and has primarily sedative effects in animal studies. It has been sold as a designer drug.
5-TFMO-DMT (5-(trifluoromethoxy)-DMT, 5-OCF3-DMT, 5-(trifluoromethoxy)-N,N-dimethyltryptamine) is a psychedelic tryptamine derivative related to drugs such as 5-MeO-DMT and DMT (DMT). It acts as an agonist at the 5-HT2A receptor with an EC50 of 127.2 nM. It was shown to release serotonin (5-HT) from synaptosomal preparations, and to reduce immobility time in the forced-swim test in animal studies, suggesting that it might have antidepressant activity.
