2C-TFM is a psychedelic phenethylamine of the 2C family. It was first synthesized in the laboratory of David E. Nichols. It has also been called 2C-CF3, a name derived from the Para-trifluoromethyl group it contains.
2C (2C-x) is a general name for the family of psychedelic phenethylamines containing methoxy groups on the 2 and 5 positions of a benzene ring. Most of these compounds also carry lipophilic substituents at the 4 position, usually resulting in more potent and more metabolically stable and longer acting compounds.
Ariadne, also known chemically as 4C-D or 4C-DOM, by its developmental code name BL-3912, and by its former tentative brand name Dimoxamine, is a little-known psychoactive drug of the phenethylamine, amphetamine, and phenylisobutylamine families. It is a homologue of the psychedelics 2C-D and DOM.
5-Hydroxytryptamine receptor 2B (5-HT2B) also known as serotonin receptor 2B is a protein that in humans is encoded by the HTR2B gene. 5-HT2B is a member of the 5-HT2 receptor family that binds the neurotransmitter serotonin (5-hydroxytryptamine, 5-HT). Like all 5-HT2 receptors, the 5-HT2B receptor is Gq/G11-protein coupled, leading to downstream activation of phospholipase C.
2,5-Dimethoxy-4-trifluoromethylamphetamine (DOTFM) is a psychedelic drug of the phenethylamine and amphetamine chemical classes. It was first synthesized in 1994 by a team at Purdue University led by David E. Nichols. DOTFM is the alpha-methylated analogue of 2C-TFM, and is around twice as potent in animal studies. It acts as an agonist at the 5-HT2A and 5-HT2C receptors. In drug-substitution experiments in rats, DOTFM fully substituted for LSD and was slightly more potent than DOI.
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. Duration of effects lasts about 3–10 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.
2,5-Dimethoxy-4-fluoroamphetamine (DOF) is a psychedelic drug of the phenethylamine and amphetamine classes. Alexander Shulgin briefly describes DOF in his book PiHKAL:
Animal studies that have compared DOF to the highly potent DOI and DOB imply that the human activity will be some four to six times less than these two heavier halide analogues.
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. They are 4-substituted derivatives of 2,5-dimethoxyamphetamine.
25D-NBOMe is a derivative of the phenethylamine derived hallucinogen 2C-D. It acts in a similar manner to related compounds such as 25I-NBOMe, which is a potent agonist at the 5-HT2A receptor. 25D-NBOMe has been sold as a street drug since 2010 and produces similar effects in humans to related compounds such as 25I-NBOMe and 25C-NBOMe. It was banned as a Temporary Class Drug in the UK on 10 June 2013 after concerns about its recreational use.
25CN-NBOH is a compound indirectly derived from the phenethylamine series of hallucinogens, which was discovered in 2014 at the University of Copenhagen. It is a member of the NBOMe family of psychedelics.
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. DMBMPP differs from 25B-NBOMe by incorporating the amine within a piperidine ring, 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.
25N-NBOMe is a derivative of the hallucinogen 2C-N. The pharmacological properties of 25N-NBOMe have not been described in the scientific literature, but it is believed to act in a similar manner to related compounds such as 25I-NBOMe and 25C-NBOMe, which are potent agonists at the 5HT2A receptor. 25N-NBOMe has been sold as a street drug and has only been described in the literature in terms of identification by forensic analysis.
25E-NBOMe is a derivative of the phenethylamine 2C-E. It acts in a similar manner to related compounds such as 25I-NBOMe, which are potent agonists at the 5-HT2A receptor. 25E-NBOMe has been sold as a drug and produces similar effects in humans to related compounds such as 25I-NBOMe and 25C-NBOMe.
The 25-NB (25x-NBx) series, or NBOMe series, also known as the N-benzylphenethylamines, is a family of serotonergic psychedelics. They are substituted phenethylamines and were derived from the 2C family. The most commonly encountered NBOMe drugs are 25I-NBOMe, 25B-NBOMe, and 25C-NBOMe.
LPH-5 is a psychedelic discovered by Emil Marcher-Rørsted, Jesper L. Kristensen and Anders A. Jensen at Danish biopharmaceutical company Lophora. It is a conformationally-restricted derivative of the phenethylamine 2C-TFM, also a hallucinogen, and acts as a potent agonist of the 5-HT2A receptor (EC50 = 3.2 nM, Emax = 78%). It shows 10- to 100-fold selectivity for the 5-HT2A receptor over the 5-HT2B and 5-HT2C receptors and, along with related compounds like 25CN-NBOH, is said to be one of the few truly selective 5-HT2A receptor agonists. LPH-5 is expected to avoid the cardiac risks of 5-HT2B receptor activation.
2C-T-21.5 is a lesser-known psychedelic drug related to compounds such as 2C-T-21 and 2C-T-28. It was originally named by Alexander Shulgin and discussed in his book PiHKAL, but was not synthesised at that time. 2C-T-21.5 was ultimately synthesised and tested by Daniel Trachsel some years later. It has a binding affinity of 146 nM at 5-HT2A and 55 nM at 5-HT2C. It produces typical psychedelic effects, being slightly less potent but somewhat longer acting than 2C-T-2 or 2C-T-21, with an active dose of 12–30 mg, and a duration of action of 8–14 hours. Unlike 2C-T-21 it will not form the highly toxic fluoroacetate as a metabolite, instead producing the less toxic difluoroacetic acid.
CYB003, or CYB-003, also known as deuterated psilocybin analogue, is a serotonergic psychedelic related to psilocybin which is under development for the treatment of major depressive disorder, alcoholism, and other psychiatric disorders. It is taken by mouth.
CYB004, or CYB-004, also known as deuterated dimethyltryptamine (dDMT), is a serotonergic psychedelic related to dimethyltryptamine (DMT) which is under development for the treatment of generalized anxiety disorder. It is administered by inhalation or intravenous injection.
CYB005, or CYB-005, also known as deuterated phenethylamine derivative, is a serotonin receptor agonist and serotonergic psychedelic which is under development for use at non-hallucinogenic doses in the treatment of psychiatric disorders and neuroinflammation.
