Summary
AI-generated from the abstractN-Benzylphenethylamines (NBOMes) are synthetic psychedelics derived from phenethylamines like 2C-X compounds, which originate from the natural alkaloid mescaline. Like other classical psychedelics, they primarily activate serotonin 2A (5-HT2A) receptors. Since their emergence as New Psychoactive Substances in 2010, recreational use has caused acute toxicity and lethal outcomes, leading to their classification as Schedule I substances in 2013. Beyond recreational use, NBOMes have become valuable biochemical tools, such as [11C]Cimbi-36 for PET imaging of 5-HT2A and 5-HT2C receptors, and 25CN-NBOH, a highly selective 5-HT2A receptor agonist. This Review covers their history, chemistry, structure-activity relationships, ADME properties, and safety profiles.

Abstract
N-Benzylphenethylamines, commonly known as NBOMes, are synthetic psychedelic compounds derived from the phenethylamine class of psychedelics (2C-X compounds), which originally have been derived from the naturally occurring alkaloid mescaline. Analogously to their parent compounds and other classical psychedelics, such as psilocybin and lysergic acid diethylamide (LSD), NBOMes are believed to exert their main pharmacological effects through activation of serotonin 2A (5-HT2A) receptors. Since their introduction as New Psychoactive Substances (NPSs) in 2010, NBOMes have been widely used for recreational purposes; this has resulted in numerous cases of acute toxicity, sometimes with lethal outcomes, leading to the classification of several NBOMes as Schedule I substances in 2013. However, in addition to their recreational use, the NBOMe class has yielded several important biochemical tools, including [11C]Cimbi-36, which is now being used in positron emission tomography (PET) studies of the 5-HT2A and 5-HT2C receptors in the mammalian brain, and 25CN-NBOH, one of the most selective 5-HT2A receptor agonists developed to date. In this Review, the history, chemistry, structure-activity relationships, ADME (absorption, distribution, metabolism, and excretion) properties, and safety profiles of NBOMes will be outlined and discussed.
