BMS-823778 is a potential therapeutic agent for type 2 diabetes mellitus.
BMS-823778 is metabolized in humans to a chiral metabolite by a polymorphic enzyme.
An LC–MS/MS assay to quantify both metabolite enantiomers has been developed/validated.
Chromatographic separation of the enantiomers was achieved by chiral chromatography.
The validated LC–MS/MS assay was used to support a human pharmacokinetic study.
