5-MeO-NBpBrT (5-Methoxy-N-(4-bromobenzyl)tryptamine) is a N-substituted member of the methoxytryptamine family of compounds. Like other such compounds it acts as an antagonist for the 5-HT2A receptor, with a claimed 100x selectivity over the closely related 5-HT2C receptor. [1] While N-benzyl substitution of psychedelic phenethylamines often results in potent 5-HT2A agonists, it had been thought that N-benzyl tryptamines show much lower efficacy and are either very weak partial agonists or antagonists at 5-HT2A, [2] [3] though more recent research has shown stronger agonist activity for 3-substituted benzyl derivatives. [4] Extending the benzyl group to a substituted phenethyl can also recover agonist activity in certain cases. [5]

MS-245

MS-245 is a tryptamine derivative used in scientific research. It acts as a selective 5-HT6 receptor antagonist with a Ki of 2.3 nM, and was derived through structure-activity relationship development of the selective 5-HT6 agonist EMDT. It has been used as a lead compound for further development of tryptamine-derived 5-HT6 antagonists. In animal studies it has been shown to boost the activity of, but not substitute for, both amphetamine and nicotine.

2CBFly-NBOMe Chemical compound

2CBFly-NBOMe is a compound indirectly derived from the phenethylamine hallucinogen 2C-B, and related to benzodifurans like 2C-B-FLY and N-benzylphenethylamines like 25I-NBOMe. It was discovered in 2002, and further researched by Ralf Heim at the Free University of Berlin, and subsequently investigated in more detail by a team at Purdue University led by David E. Nichols. It acts as a potent partial agonist for the 5HT2A serotonin receptor subtype.

TFMFly Chemical compound

TFMFly is a compound related to psychedelic phenethylamines such as 2C-B-FLY and 2C-TFM. It was first reported in 2005 by a team at Purdue University led by David Nichols. It acts as a potent agonist at the 5HT2A serotonin receptor subtype, and is a chiral compound with the more active (R) enantiomer having a Ki of 0.12 nM at the human 5HT2A receptor. While the fully aromatic benzodifurans such as bromodragonfly generally have higher binding affinity than saturated compounds like 2C-B-FLY, the saturated compounds have higher efficacy as agonists.

25I-NBMD

25I-NBMD is a derivative of the phenethylamine hallucinogen 2C-I, discovered in 2006 by a team at Purdue University led by David Nichols. It acts as a potent partial agonist for the 5HT2A receptor with a Ki of 0.049 nM at the human 5HT2A receptor. The corresponding 4-bromo analogue 25B-NBMD has been used for molecular dynamics studies on the shape of the 5-HT2A receptor.

25B-NBOMe Chemical compound

25B-NBOMe is a derivative of the phenethylamine psychedelic 2C-B, discovered in 2004 by Ralf Heim at the Free University of Berlin. It acts as a potent full agonist for the 5HT2A receptor. Anecdotal reports from users suggest 25B-NBOMe to be an active hallucinogen at a dose of as little as 250–500 µg, making it a similar potency to other phenethylamine derived hallucinogens such as Bromo-DragonFLY. Duration of effects lasts about 12–16 hours, although the parent compound is rapidly cleared from the blood when used in the radiolabeled form in tracer doses. Recently, Custodio et. al (2019) evaluated the potential involvement of dysregulated dopaminergic system, neuroadaptation, and brain wave changes which may contribute to the rewarding and reinforcing properties of 25B-NBOMe in rodents.

DO<em>x</em> Class of chemical compounds

4-Substituted-2,5-dimethoxyamphetamines (DOx) is a chemical class of substituted amphetamine derivatives featuring methoxy groups at the 2- and 5- positions of the phenyl ring, and a substituent such as alkyl or halogen at the 4- position of the phenyl ring. Most compounds of this class are potent and long-lasting psychedelic drugs, and act as highly selective 5-HT2A, 5-HT2B, and 5-HT2C receptor partial agonists. A few bulkier derivatives such as DOAM have similarly high binding affinity for 5-HT2 receptors but instead act as antagonists, and so do not produce psychedelic effects though they retain amphetamine-like stimulant effects.

RH-34 Chemical compound

RH-34 is a compound which acts as a potent and selective partial agonist for the 5-HT2A serotonin receptor subtype. It was derived by structural modification of the selective 5-HT2A antagonist ketanserin, with the 4-(p-fluorobenzoyl)piperidine moiety replaced by the N-(2-methoxybenzyl) pharmacophore found in such potent 5-HT2A agonists as NBOMe-2C-B and NBOMe-2C-I. This alteration was found to retain 5-HT2A affinity and selectivity, but reversed activity from an antagonist to a moderate efficacy partial agonist.

5-Methoxy-7,<i>N</i>,<i>N</i>-trimethyltryptamine

5-Methoxy-7,N,N-trimethyltryptamine (5-MeO-7,N,N-TMT, 5-MeO-7-TMT), is a tryptamine derivative which acts as an agonist at the 5-HT2 serotonin receptors. 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.

25I-NBF Chemical compound

25I-NBF is a derivative of the phenethylamine hallucinogen 2C-I, which acts as a highly potent partial agonist for the human 5-HT2A receptor. It has been studied in its 11C radiolabelled form as a potential ligand for mapping the distribution of 5-HT2A receptors in the brain, using positron emission tomography (PET).

25TFM-NBOMe

25TFM-NBOMe is a derivative of the phenethylamine hallucinogen 2C-TFM, discovered in 2004 by Ralf Heim at the Free University of Berlin. It acts as a potent partial agonist for the 5HT2A receptor, though its relative potency is disputed, with some studies finding it to be of lower potency than 25I-NBOMe, while others show it to be of similar or higher potency, possibly because of differences in the assay used. 2C-TFM-NB2OMe can be taken to produce psychedelic effects similar to 2C-I-NB2OMe and 2C-D-NB2OMe.

Substituted tryptamine

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.

DMBMPP

DMBMPP, or 2-(2,5-dimethoxy-4-bromobenzyl)-6-(2-methoxyphenyl)piperidine, is a 2-benzylpiperidine analog of the hallucinogenic N-benzylphenethylamine 25B-NBOMe and was discovered in 2011 by Jose Juncosa in the group of David E. Nichols at Purdue University. DMBPP differs from 25B-NBOMe by having a piperidine ring conformed to the amine, making for a more rigid molecular structure than that of the open-chain 25B-NBOMe. The presence of the piperidine ring introduces two stereocenters, thus, four stereoisomers of this compound can be made.

25CN-NBOMe

25CN-NBOMe is a derivative of the phenethylamine 2C-CN. It acts in a similar manner to related compounds such as 25I-NBOMe, which are potent agonists at the 5HT2A receptor.

25B-NBOH

25B-NBOH is a derivative of the phenethylamine derived hallucinogen 2C-B which has been sold as a designer drug. It acts as a potent serotonin receptor agonist with similar affinity to the better-known compound 25B-NBOMe at 5-HT2A and 5-HT2C receptors with pKis values of 8.3 and 9.4, respectively.

25-NB

The 25-NB (25x-NBx) series, sometimes alternatively referred to as the NBOMe compounds, is a family of serotonergic psychedelics. They are substituted phenethylamines and were derived from the 2C family. They act as selective agonists of the serotonin 5-HT2A receptor. The 25-NB family is unique relative to other classes of psychedelics in that they are, generally speaking, extremely potent and relatively selective for the 5-HT2A receptor.

25E-NBOH Chemical compound

25E-NBOH is a derivative of the phenethylamine derived hallucinogen 2C-E. It was first developed by Martin Hansen at the University of Copenhagen in 2010 as a brain imaging agent, but has subsequently been sold as a designer drug, first being identified in Brazil in 2018 on seized blotter paper, as well as in Slovenia. It acts as a potent serotonin receptor agonist with similar affinity to better-known compounds such as 25I-NBOMe at 5-HT2A and 5-HT2C receptors.
