Phase I Metabolism of Novel Phencyclidine Derivative 3‐Cl‐PCP: In Vitro Studies With Pooled Human Liver Microsomes and Investigation of a Post‐Mortem Case

Drug Testing and Analysis, EarlyView.
A fatal 3‐chloro‐phencyclidine (3‐Cl‐PCP) intoxication was investigated by analyzing postmortem samples and a pooled human liver microsomes assay. Tentative metabolite identification was performed by liquid chromatography‐quadrupole time‐of‐flight mass spectrometry (LC‐QTOF‐MS). Seven phase I metabolites were identified.

Identification of Synthetic Urine by Analysis of Stable Carbon and Nitrogen Isotope Ratios and Comparison to Established GC‐MS/MS and LC‐MS/MS Analysis

Drug Testing and Analysis, EarlyView.
This study compared GC‐MS/MS, EA‐IRMS, and LC‐MS/MS for detecting synthetic and manipulated urine samples in doping control and forensic analysis. EA‐IRMS proved particularly effective for identifying mixtures of synthetic and authentic urine, providing a reliable complement to established authenticity testing methods.

Detection of Testosterone Esters in Urine: Evidence of Trace‐Level Detectability in Doping Control Samples

Drug Testing and Analysis, EarlyView.
An ultrasensitive LC‐MS/MS method for detecting testosterone esters (T‐esters) in urine at sub–pg/mL levels is presented. This approach, employing Girard P derivatization, provides the first evidence of T‐esters' trace‐level detectability in human urine.
