The identification of human derived metabolites is an imperative step in drug discovery and development process. Typical studies are conducted in human in vitro systems and metabolites are identified utilizing HPLC-MS/MS. Human
hepatocyte co-culture is a new in vitro system, which is comprised of a mixture of hepatocytes and fibroblast cells, capable of remaining viable and highly functional
for up to 4 weeks. In this presentation, the application of high resolution mass spectrometry (HRMS), ultrahigh-pressure liquid chromatography (UHPLC), full scan acquisition, and Sequential Window acquisition of All THeoretical fragment ion spectra (SWATH™) was used to profile and characterize metabolites of
diclofenac, linezolid, and ziprasidone following incubations in human hepatocyte co-cultures.
