DOB-2-DRAGONFLY-5-BUTTERFLY is a drug with an unusual furo[2,3-g]chromene core structure which acts as a 5-HT2A receptor agonist. It was first synthesised by David E. Nichols and colleagues in 2008, and while it is weaker than similar compounds such as Bromo-DragonFLY it is still the most potent among a number of related derivatives. [1] [2]
2C-B (4-bromo-2,5-dimethoxyphenethylamine) is a synthetic psychedelic drug of the 2C family, mainly used as a recreational drug. The substance was first synthesized by Alexander Shulgin in 1974, and gained an initial reputation for potential psychotherapeutic use, but its use has been limited to mainly recreational use. To date, there is limited scientific information regarding the drug's pharmacokinetics and pharmacological effects in humans. The existing studies primarily classify 2C-B as a stimulant, and hallucinogen, and less commonly as an entactogen, and empathogen.
Dimethoxybromoamphetamine (DOB), also known as brolamfetamine (INN) and bromo-DMA, is a psychedelic drug and substituted amphetamine of the phenethylamine class of compounds. DOB was first synthesized by Alexander Shulgin in 1967. Its synthesis and effects are documented in Shulgin's book PiHKAL: A Chemical Love Story.
Bromo-DragonFLY is a substance related to the phenethylamine family. It acts as a potent full agonist for the 5-HT2A receptor.
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-B-FLY is a psychedelic phenethylamine and designer drug of the 2C family. It was first synthesized in 1996 by Aaron Monte, Professor of Chemistry at UW-La Crosse.
Ψ-DOM, or 2,6-dimethoxy-4-methylamphetamine, is a hallucinogenic, psychedelic drug and a structural isomer of the better-known hallucinogen DOM. Ψ-DOM was first reported by Alexander Shulgin in his book PiHKAL.
2CBCB-NBOMe (NBOMe-TCB-2) is a compound indirectly derived from the phenethylamine series of hallucinogens, which was discovered in 2007 at Purdue University as part of the ongoing research program of the team led by David Nichols focusing on the mapping of the specific amino acid residues responsible for ligand binding to the 5HT2A receptor. 2CBCB-NBOMe acts as a potent and selective agonist for the 5-HT2A and 5-HT2C receptors, with a Ki of 0.27 nM at the human 5-HT2A receptor, a similar potency to other agonists such as TCB-2, NBOMe-2C-I and Bromo-DragonFLY.
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 5-HT2A serotonin receptor subtype.
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 5-HT2A receptor. While the fully aromatic benzodifurans such as Bromo-DragonFLY generally have higher binding affinity than saturated compounds like 2C-B-FLY, the saturated compounds have higher efficacy as agonists.
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.
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.
2CB-Ind is a conformationally-restricted derivative of the phenethylamine hallucinogen 2C-B, discovered in 1974 by Alexander Shulgin. It acts as a moderately potent and selective agonist for the 5-HT2A and 5-HT2C receptors, but unlike the corresponding benzocyclobutene derivative TCB-2 which is considerably more potent than the parent compound 2C-B, 2CB-Ind is several times weaker, with racemic 2CB-Ind having a Ki of 47nM at the human 5-HT2A receptor, only slightly more potent than the mescaline analogue (R)-jimscaline.
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.
2C-B-BUTTERFLY is a conformationally-restricted derivative of the phenethylamine hallucinogen 2C-B, which was discovered in 1999 by Michael S. Whiteside and Aaron Monte. It is a ring-expanded homologue of the better known compound 2C-B-FLY, and has similar properties as an agonist for serotonin receptors, but with more selectivity for 5-HT2C over 5-HT2A.
The substituted benzofurans are a class of chemical compounds based on the heterocyclyc and polycyclic compound benzofuran. Many medicines use the benzofuran core as a scaffold, but most commonly the term is used to refer to the simpler compounds in this class which include numerous psychoactive drugs, including stimulants, psychedelics and empathogens. In general, these compounds have a benzofuran core to which a 2-aminoethyl group is attached, and combined with a range of other substituents. Some psychoactive derivatives from this family have been sold under the name Benzofury.
25B-NBF is a derivative of the phenethylamine hallucinogen 2C-B, which acts as a highly potent partial agonist for the human 5-HT2A receptor.
4C-B is a lesser-known psychedelic drug which is related to 2C-B and DOB. It is a reasonably potent 5-HT2A receptor partial agonist with a Ki of 7.6nM, but has relatively low efficacy. It is briefly mentioned in Alexander Shulgin's book PiHKAL but was never tested by him, however it has subsequently been tested by other researchers and was found to be active in a dose range of 50-80mg with a duration of around 8 hours, though with generally milder effects than 2C-B or DOB.
DOB-FLY is a recreational designer drug with psychedelic effects. It can be regarded as the alpha-methyl derivative of 2C-B-FLY or the partially saturated counterpart of bromo-dragonfly. Unlike bromo-dragonfly, DOB-FLY is only slightly more potent than DOB itself, with an active dose in humans of around 1 mg.
2C-B-DRAGONFLY (2C-B-DFLY) is a recreational designer drug with psychedelic effects. It can be regarded as the fully aromatic derivative of 2C-B-FLY. 2C-B-DRAGONFLY is stronger than 2C-B or 2C-B-FLY with around 2-3x the potency of 2C-B in animal studies, demonstrating the importance of the fully aromatic benzodifuran ring system for optimum receptor binding at 5-HT2A, but it is still considerably less potent than its alpha-methyl derivative Bromo-DragonFLY.
2C-E-FLY is a recreational designer drug with psychedelic effects. It is slightly less potent than 2C-E or 2C-B-FLY in animal studies but retains drug-appropriate responding.
