abstract = {Metabolite reference standards are often not available,
which results in a lack of MS/MS spectra for library
matching. Consequently, the identification of suspected
metabolites proves to be challenging. The present study aims
at structurally elucidating the MS/MS fragmentation behavior
of selected benzimidazole anthelmintics to theoretically
predict characteristic product ions for rapid and systematic
tentative metabolite identification. A set of common
characteristic product ions was identified from accurate
mass MS/MS experiments for five parent compounds. It was
hypothesized that the mass shift of any metabolic
transformation at the parent molecule also is observable in
the mass spectrum of the corresponding metabolite. This was
tested and verified with six metabolite reference standards
and subsequently, formulated as a general prediction scheme.
The approach was integrated into a rapid MSeQTOF workflow
and tested in mouse plasma for mebendazole and its
metabolites. The presented scheme allows the prediction of
characteristic product ions for suspected unknown
metabolites. These can be matched with measured product ions
of suspected metabolites for tentative identification. The
theoretically predicted spectra can contribute to the
tentative identification of unknown compounds in non-target
and suspect screening approaches.},
