Pentylone (β-Keto-Methyl​benzo​dioxolyl​pentanamine, βk-Methyl-Kβk-MBDPmethyl​enedioxy​pentedrone, or 1‐(3,4‐methylenedioxyphenyl)‐2‐(methylamino)pentan‐1‐one[1]) is a stimulant developed in the 1960s.[2] It is a substituted cathinone (a type of substituted phenethylamine). It has been identified in some samples of powders sold as “NRG-1”, along with varying blends of other cathinone derivatives flephedrone, MDPBP, MDPV and 4-MePPP. It was also found in combination with 4-MePPP being sold as “NRG-3”.[1] Reports indicate side effects include feelings of paranoia, agitation and inability to sleep, with effects lasting for several days at high doses.


N-ethyl pentylone (ephylone) has been identified as the most recent novel stimulant to emerge into the arena of evolving novel psychoactive substances (NPS). Due to its novelty, information regarding case reports with associated quantitative confirmations, biotransformation pathways, and identified unique metabolites will assist the scientific community in understanding the implications of the emergence and risks associated with N-ethyl pentylone use. Authentic blood specimens (n = 26) submitted as part of toxicological death investigations or drugged driving casework tested positive for N-ethyl pentylone, and were quantitatively analyzed by liquid chromatography tandem mass spectrometry (LC–MS-MS). pentylone concentrations ranged from 12 to 1,200 ng/mL, with mean (±standard deviation) and median concentrations of 313 (±366) and 125 ng/mL, respectively, excluding one case measured at 50,000 ng/mL. N-ethyl pentylone was often found in combination with other drugs of abuse and NPS, include a variety of novel opioids including fentanyl analogs. Oral fluid specimens (n = 5), collected from recreational drug users at a dance music festival, were quantitatively analyzed using LC–MS-MS. Concentrations ranged from 12.6 to 1,377 ng/mL. analysis was performed to characterize the metabolic profile of N-ethyl pentylone using human liver microsomes (HLM), followed by confirmation of the presence of the proposed metabolites in a subset of the blood specimens and oral fluid specimens. Metabolomic analysis was performed using a liquid chromatograph quadrupole time-of-flight mass spectrometer (LC-QTOF), followed by data processing using MetabolitePilot™ software. In vivo verification of in vitro HLM-generated metabolites resulted in the confirmation of four metabolites. Reduction of the beta-ketone to an alcohol resulted in the most prominent metabolite found in the authentic specimens, and its uniqueness to N-ethyl pentylone leads to this metabolite being an appropriate biomarker to determine N-ethyl pentylone ingestion. This is the first study to report N-ethyl pentylone concentrations and to characterize the metabolic profile of N-ethyl pentylone.
