Validation of ion mobility spectrometry ‐ mass spectrometry as a screening tool to identify type II kinase inhibitors of FGFR1 kinase

Rapid Communications in Mass Spectrometry, Volume 39, Issue S1, May 2025.
Rationale The protein kinase FGFR1 regulates cellular processes in human development. As over‐activity of FGFR1 is implicated with cancer, effective inhibitors are in demand. Type I inhibitors, which bind to the active form of FGFR1, are less effective than type II inhibitors, which bind to the inactive form. Screening to distinguish between type I and
