Identification and Characterization of the Designer Opioid N‐Pyrrolidino Fluetonitazene in Nasal Spray

open access: yesDrug Testing and Analysis, EarlyView.
N‐Pyrrolidino fluetonitazene, a synthetic opioid, was identified and characterized in a nasal spray using GC‐MS, LC‐QTOF‐MS, NMR and FT‐IR. ABSTRACT Detection of drugs in non‐biological samples serves as a fundamental basis for identifying emerging trends in the field of new psychoactive substances and provides valuable information for optimizing ...

Investigation of the In Vitro and In Vivo Metabolism and μ‐Opioid Receptor Affinity of the Nitazene N‐Pyrrolidino Fluetonitazene

open access: yesDrug Testing and Analysis, EarlyView.
Eight metabolites for N‐pyrrolidino fluetonitazene were identified in vitro, three of which (M2, M6 and M8) were present in an authentic urine sample. M2 was the most abundant in vivo metabolite and is a common marker metabolite of nitazepyne‐type substances.

Development of an Efficient and Scalable Process for Preparing Timolol N‐Nitrosamine Impurities B, C, E, H, I, J, and Their ADMET Evaluation

open access: yesJournal of Heterocyclic Chemistry, EarlyView.
N‐nitrosamine impurities (B, C, E, H, I, J) of timolol maleate are easily synthesized from diethyl malonate and 3,4‐dichloro‐1,2,5‐thiadiazole. Good yields and precise impurity profiling are made possible by the effective technique, which also ensures pharmaceutical safety and strengthens regulatory compliance.
