Neuroblastoma is one of the representative childhood cancers and a highly heterogeneous disease affected by factors such as age at diagnosis, stage, and tumor biology. Multidrug regimen chemotherapy has been ongoing for high-risk patients and requires customizing to maximize treatment efficiency. To improve the outcomes for neuroblastoma, many research groups and institutes have developed precision medicine (personalized-medicine) using biochemical methods such as genomics and proteomics. Among them, pharmacogenomics and pharmacoproteomics are broader academic fields that identify genes or proteins involved in drug response or disease occurrence. Therefore, It is important to verify pharmacokinetics to develop pharmacogenomics and pharmacoproteomics. In this study, we establish a drug quantitation method for verifying pharmacokinetics using mass spectrometry. Quantitative analysis of Intracellular antidrug was performed using multiple reaction monitoring (MRM) analysis using RPLC-triple quadrupole mass spectrometry. For precise quantitative analysis, the mechanism of fragmentation used in MRM analysis was also investigated. Fragmentation pathways of anticancer drugs were identified using ion mobility mass spectrometry (IM-MS).
