25N-NBOMe (2C-N-NBOMe, NBOMe-2C-N) 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. [2] [3] 25N-NBOMe has been sold as a street drug and has only been described in the literature in terms of identification by forensic analysis. [4] [5]
25N-NBOMe is a selective and highly potent agonist of the serotonin 5-HT2 receptors. [6] Its affinities (Ki) are 0.144 nM at the serotonin 5-HT2A receptor, 8.7 nM at the serotonin 5-HT2B receptor, and 1.06 nM at the serotonin 5-HT2C receptor. [6] In terms of affinity, the drug has approximately 7.4-fold selectivity for the serotonin 5-HT2A receptor over the serotonin 5-HT2C receptor and 60-fold selectivity for the 5-HT2A receptor over the serotonin 5-HT2B receptor. [6]
The EC50 (Emax ) values of 25N-NBOMe are 0.51 nM (87.9%) at the serotonin 5-HT2A receptor, 47 nM (57.6%) at the serotonin 5-HT2B receptor, and 1.32 nM (99.4%) at the serotonin 5-HT2C receptor. [6] Hence, 25N-NBOMe is a full agonist of the serotonin 5-HT2A and 5-HT2C receptors and a partial agonist of the serotonin 5-HT2B receptor. [6] In terms of functional activity, 25N-NBOMe had 2.6-fold selectivity for the serotonin 5-HT2A receptor over the serotonin 5-HT2C receptor and 92-fold selectivity for the serotonin 5-HT2A receptor over the serotonin 5-HT2C receptor. [6]
Unlike many other serotonergic psychedelics, 25N-NBOMe has shown reinforcing effects in rodents, including in terms of conditioned place preference (CPP) and self-administration. [7]
NBOMe compounds are often associated with life-threatening toxicity and death. [8] [9] Studies on NBOMe family of compounds demonstrated that the substance exhibit neurotoxic and cardiotoxic activity. [10] Reports of autonomic dysfunction remains prevalent with NBOMe compounds, with most individuals experiencing sympathomimetic toxicity such as vasoconstriction, hypertension and tachycardia in addition to hallucinations. [11] [12] [13] [14] [15] Other symptoms of toxidrome include agitation or aggression, seizure, hyperthermia, diaphoresis, hypertonia, rhabdomyolysis, and death. [11] [15] [9] Researchers report that NBOMe intoxication frequently display signs of serotonin syndrome. [16] The likelihood of seizure is higher in NBOMes compared to other psychedelics. [10]
NBOMe and NBOHs are regularly sold as LSD in blotter papers, [9] [17] which have a bitter taste and different safety profiles. [11] [8] Despite high potency, recreational doses of LSD have only produced low incidents of acute toxicity. [8] Fatalities involved in NBOMe intoxication suggest that a significant number of individuals ingested the substance which they believed was LSD, [13] and researchers report that "users familiar with LSD may have a false sense of security when ingesting NBOMe inadvertently". [11] While most fatalities are due to the physical effects of the drug, there have also been reports of death due to self-harm and suicide under the influence of the substance. [18] [19] [11]
Given limited documentation of NBOMe consumption, the long-term effects of the substance remain unknown. [11] NBOMe compounds are not active orally, [a] and are usually taken sublingually. [21] : 3 When NBOMes are administered sublingually, numbness of the tongue and mouth followed by a metallic chemical taste was observed, and researchers describe this physical side effect as one of the main discriminants between NBOMe compounds and LSD. [22] [23] [24]Many of the NBOMe compounds have high potency agonist activity at additional 5-HT receptors and prolonged activation of 5-HT2B can cause cardiac valvulopathy in high doses and chronic use. [9] [14] 5-HT2B receptors have been strongly implicated in causing drug-induced valvular heart disease. [25] [26] [27] The high affinity of NBOMe compounds for adrenergic α1 receptor has been reported to contribute to the stimulant-type cardiovascular effects. [14]
In vitro studies, 25C-NBOMe has been shown to exhibit cytotoxicity on neuronal cell lines SH-SY5Y, PC12, and SN471, and the compound was more potent than methamphetamine at reducing the visibility of the respective cells; the neurotoxicity of the compound involves activation of MAPK/ERK cascade and inhibition of Akt/PKB signaling pathway. [10] 25C-NBOMe, including the other derivative 25D-NBOMe, reduced the visibility of cardiomyocytes H9c2 cells, and both substances downregulated expression level of p21 (CDC24/RAC)-activated kinase 1 (PAK1), an enzyme with documented cardiac protective effects. [10]
Preliminary studies on 25C-NBOMe have shown that the substance is toxic to development, heart health, and brain health in zebrafish, rats, and Artemia salina , a common organism for studying potential drug effects on humans, but more research is needed on the topic, the dosages, and if the toxicology results apply to humans. Researchers of the study also recommended further investigation of the drug's potential in damaging pregnant women and their fetus due to the substance's damaging effects to development.

25N-NBOMe is illegal in Hungary. [31]
The Riksdag added 25N-NBOMe to Narcotic Drugs Punishments Act under swedish schedule I ("substances, plant materials and fungi which normally do not have medical use") as of January 16, 2015, published by Medical Products Agency (MPA) in regulation LVFS 2014:11 listed as 25N-NBOMe, and 2-(2,5-dimetoxi-4-nitrofenyl)-N-(2-metoxibensyl)etanamin. [32]
This substance is a Class A drug in the United Kingdom as a result of the N-benzylphenethylamine catch-all clause in the Misuse of Drugs Act 1971 . [33]
A serotonin receptor agonist is an agonist of one or more serotonin receptors. They activate serotonin receptors in a manner similar to that of serotonin, a neurotransmitter and hormone and the endogenous ligand of the serotonin receptors.
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.
25I-NBOH is a derivative of the phenethylamine-derived hallucinogen 2C-I that was discovered in 2006 by a team at Purdue University.
25I-NBOMe, also known as Smiles, or N-Bomb, is a novel synthetic psychoactive substance with strong hallucinogenic properties, synthesized in 2003 for research purposes. Since 2010, it has circulated in the recreational drug scene, often misrepresented as LSD.
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.
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 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.
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 5-HT2A 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.
25C-NBOMe is a psychedelic drug and derivative of the psychedelic phenethylamine 2C-C. 25C-NBOMe appeared on online vendor sites in 2010 but was not reported in the literature until 2011. It acts as a potent agonist of the 5-HT2A receptor, and 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). Multiple deaths have occurred from usage of 25C-NBOMe due to the ease of accidental overdose. The long-term toxic effects of the drug have not been researched.
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.

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 and France. 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.
Recently, a new class of psychedelic compounds named NBOMe (or 25X-NBOMe) has appeared on the illegal drug market. NBOMes are analogs of the 2C family of phenethylamine drugs, originally synthesized by Alexander Shulgin, that contain a N-(2-methoxy)benzyl substituent. The most frequently reported drugs from this group are 25I-NBOMe, 25B-NBOMe, and 25C-NBOMe. NBOMe compounds are ultrapotent and highly efficacious agonists of serotonin 5-HT2A and 5-HT2C receptors (Ki values in low nanomolar range) with more than 1000-fold selectivity for 5-HT2A compared with 5-HT1A. They display higher affinity for 5-HT2A receptors than their 2C counterparts and have markedly lower affinity, potency, and efficacy at the 5-HT2B receptor compared to 5-HT2A or 5-HT2C.
