Review demonstrates integrated chromatographic and mass spectrometry techniques for drug metabolite identification, highlighting combined chemical workflows to overcome matrix interference.

Key Points

To review bioanalytical strategies and workflow integrations for determining the metabolic stability, biotransformation pathways, and structural characterization of new chemical entities.
Evaluated liquid chromatography coupled with atmospheric pressure ionization mass spectrometry (LC-API-MS) for metabolite quantification in biological fluids.
Examined complementary structural elucidation tools including LC-NMR, enzymatic hydrolysis, chemical derivatization, and hydrogen/deuterium exchange.
Assessed sample preparation protocols developed to reduce endogenous matrix interference and mass spectrometer ion suppression.
Liquid chromatography coupled with tandem mass spectrometry provides rapid detection and quantification of circulatory and excretory drug metabolites.
Mass spectrometry alone exhibits limitations in differentiating structural isomers and precise oxidation sites without complementary wet chemistry or NMR techniques.
Optimized sample introduction and preparation protocols mitigate biological matrix effects that otherwise quench analyte ionization signals.
