title: Studies on the metabolism and detectability of the emerging drug of abuse diphenyl-2-pyrrolidinemethanol (D2PM) in rat urine using GC-MS and LC-HR-MS/MS.
abstract: In the last years, the number of new psychoactive substances, so-called 'legal highs', has enormously increased. They are sold via online shops often with inaccurate and false information about the content. The aim of this work was to study the metabolism and the detectability of the drug of abuse diphenyl-2-pyrrolidinemethanol (D2PM) in rat urine using gas chromatography-mass spectrometry and liquid chromatography-high resolution-tandem mass spectrometry. Five phase I and two phase II metabolites were identified suggesting hydroxylation at the pyrrolidine and diphenyl part as the main metabolic steps. Assuming similar kinetics, an intake of D2PM should be detectable in human urine mainly via its metabolites.
