The metabolism of the psychoactive compound 2C-B-Fly-NBOMe was investigated using three systems: human liver microsomes, the fungus Cunninghamella elegans, and live rats. Thirty-five phase I and nine phase II metabolites were identified. Major metabolic pathways include hydroxylation, O-demethylation, oxidative debromination, and N-demethoxybenzylation, followed by glucuronidation or N-acetylation. Human liver microsomes produced the most metabolites at highest concentrations. Two poly-hydroxylated metabolites appeared only in rat urine, while the fungus generated dehydrogenated, N-oxygenated, and dibrominated metabolites. These findings clarify how the body processes this substance, aiding understanding of its effects and potential toxicity.

N-Benzylphenethylamines, including 25CN-NBOMe, are novel psychedelic substances with limited metabolism data. This study investigated the metabolic profile of 25CN-NBOMe in rats in vivo and in human liver microsomes and Cunninghamella elegans mycelium in vitro. Major metabolic pathways include mono- and bis-O-demethylation, hydroxylation, and combinations, followed by glucuronidation, sulfation, or N-acetylation of primary metabolites. The cyano group was either hydrolyzed to an amide or carboxylic acid or remained unchanged. Differences between species should be considered in metabolism studies of novel substances.

25CN-NBOMe, a substance related to LSD, readily crosses the blood-brain barrier in rats. After a 5 mg/kg dose, drug concentration peaked in blood and brain at 1 hour, with half-lives of 1.88 and 2.28 hours. The drug is classified as toxicity category 3, with a lethal dose of 300 mg/kg and an estimated LD50 of 200 mg/kg. Histological findings suggest acute cardiovascular arrest from malignant arrhythmia at lethal doses. A 5 mg/kg dose reduced body temperature in individually housed rats. Lower doses (0.2 and 1 mg/kg) reduced locomotor activity and increased anxiety, while 5 mg/kg also impaired sensorimotor gating. The drug's behavioral effects are comparable to other NBOMes.
