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. [1] [2] [3] It has been sold as a designer drug. [4]
N,N-Dimethyltryptamine is a substituted tryptamine that occurs in many plants and animals, including human beings, and which is both a derivative and a structural analog of tryptamine. It is used as a psychedelic drug and prepared by various cultures for ritual purposes as an entheogen.
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.
5,N,N-trimethyltryptamine is a tryptamine derivative that is a psychedelic drug. It was first made in 1958 by E. H. 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-Fluoro-α-methyltryptamine, also known as PAL-544, is a putative stimulant, entactogen, and psychedelic tryptamine derivative related to α-methyltryptamine (αMT). It has been found to act as a well-balanced serotonin-norepinephrine-dopamine releasing agent, a 5-HT2A receptor agonist, and a potent and specific MAO-A inhibitor. which suggests that 5-fluoro-αMT could be an active psychedelic in humans, although it is not known to have been tested in humans and could be dangerous due to its strong inhibition of MAO-A.
A serotonin–dopamine releasing agent (SDRA) is a type of drug which induces the release of serotonin and dopamine in the body and/or brain.
5-Fluoro-N,N-dimethyltryptamine is a tryptamine derivative related to compounds such as 5-bromo-DMT and 5-MeO-DMT. Fluorination of psychedelic tryptamines either reduces or has little effect on 5-HT2A/C receptor affinity or intrinsic activity, although 6-fluoro-DET is inactive as a psychedelic despite acting as a 5-HT2A agonist, while 4-fluoro-5-methoxy-DMT is a much stronger agonist at 5-HT1A than 5-HT2A.
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.
7-Methyl-α-ethyltryptamine (7-Me-αET) is a tryptamine derivative related to α-ethyltryptamine (αET). It was discovered by a team at Upjohn in the early 1960s. It has similar pharmacological effects to αET, but is both 3-4 times more potent as a serotonin releasing agent, and 10 times more potent as a monoamine oxidase inhibitor, making it potentially hazardous as this pharmacological profile is shared with drugs such as PMA and 4-MTA, which are known to be dangerous in humans when used at high doses.
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.
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.
6-Fluoro-α-methyltryptamine is a tryptamine derivative related to compounds such as alpha-methyltryptamine and 5-MeO-AMT, which has been sold as a designer drug. Animal tests showed it to be somewhat less active than AMT or 5-fluoro-AMT, but it was nevertheless allegedly manufactured and sold from the laboratory operated by Leonard Pickard and Gordon Todd Skinner, who described 6-fluoro-AMT as "a beast".
ST-1936 (2-methyl-5-chloro-N,N-dimethyltryptamine) is a tryptamine derivative which is used in scientific research. It acts as a selective 5-HT6 receptor agonist, with a Ki of 13 nM, and much weaker action at 5-HT2B and 5-HT7 subtypes. In animal studies it has been found to increase dopamine and noradrenaline mediated signalling but decreases glutamatergic transmission, and has antidepressant effects.
5-Chloro-α-methyltryptamine (5-Chloro-αMT), also known as PAL-542, is a tryptamine derivative related to α-methyltryptamine (αMT) and one of only a few known specific serotonin-dopamine releasing agents (SDRAs). It has been investigated in animals as a potential treatment for cocaine dependence. The EC50 values of 5-chloro-αMT in evoking the in vitro release of serotonin (5-HT), dopamine (DA), and norepinephrine (NE) in rat synaptosomes were reported as 16 nM, 54 nM, and 3434 nM, with an NE/DA ratio of 63.6 and a DA/5-HT ratio of 3.38, indicating that it is a highly specific and well-balanced SDRA. However, 5-chloro-αMT has also been found to act as a potent full agonist of the 5-HT2A receptor, with an EC50 value of 6.27 nM and an efficacy of 105%, and almost assuredly acts as a potent agonist of other serotonin receptors as well.
5-MeO-MET (5-Methoxy-N-methyl-N-ethyltryptamine) is a relatively rare designer drug from the substituted tryptamine family, related to compounds such as N-methyl-N-ethyltryptamine and 5-MeO-DMT. It was first synthesised in the 1960s and was studied to a limited extent, but was first identified on the illicit market in June 2012 in Sweden. It was made illegal in Norway in 2013, and is controlled under analogue provisions in numerous other jurisdictions.
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.
7-Chloro-α-methyltryptamine (7-Cl-AMT) is a tryptamine derivative with stimulant effects, invented in the 1960s. It is a weak monoamine oxidase inhibitor but its pharmacology has not otherwise been studied by modern techniques, though several closely related compounds are known to act as serotonin–dopamine releasing agents and agonists of the 5-HT2A receptor.
5-Fluoro-α-ethyltryptamine (5-F-AET) is a tryptamine derivative which acts as a serotonin–dopamine releasing agent and agonist of the 5-HT2A receptor.
5-Fluoro-EPT (5F-EPT, 5-fluoro-N-ethyl-N-propyltryptamine) is a psychedelic tryptamine derivative related to drugs such as EPT and 5-MeO-EPT. It acts as a potent full agonist at the 5-HT2A receptor with an EC50 of 5.54 nM and an efficacy of 104% (compared to serotonin). It produces a head-twitch response in animal studies, and is claimed to have antidepressant activity.
7F-5-MeO-MET (5-MeO-7F-MET, 5-Methoxy-7-fluoro-N-methyl-N-ethyltryptamine) is a tryptamine derivative which acts as a serotonin receptor agonist selective for the 5-HT2 subtypes, with a pEC50 of 8.71 at 5-HT2A, vs 8.25 at 5-HT2B and 7.69 at 5-HT2C. In animal tests it produced the most potent head-twitch response of a range of related fluorinated tryptamine derivatives tested, though still with slightly lower potency than psilocybin.
