“…In addition, there is currently no technique for maintaining the E and Z forms separately in a liquid sample, and therefore we cannot perform accurate absolute quantification using these standard products. This issue was addressed by converting the E form to the Z form by heat-treating the sample according to the reports by Posocco et al [25] and Marangon et al [26]. Although details of the conversion efficiency from the E to the Z form by heating have not been clarified, at least in the analysis of sunitinib N-oxide using our method, no E form of sunitinib N-oxide was detected, and no sunitinib E form was also detected when analyzed using our method, which can detect sunitinib at concentrations 20 times lower than the lower limit of detection of methods used in previous reports (data not shown).…”

“…The sunitinib content in blood was determined using LC‐MS/MS. [ 50 ] 50 µL plasma was mixed with 150 µL methanol and 10 µL dasatinib in methanol (internal standard, 50 ng mL −1 ). After vertexing for 10 s, the sample was centrifuged at 13 000 rpm for 10 min at 4 °C to separate the supernatant.…”

“…The narrow therapeutic window and the positive ratio of exposure to the effectiveness of sunitinib indicates the need for its therapeutic drug monitoring. For the determination of sunitinib and its active metabolite N -desethyl sunitinib in patients’ plasma samples, the LC-MS/MS method was applied [ 40 ]. In solution, sunitinib and N -desethyl sunitinib undergo photoisomerization and procedures of samples collection and handling under strict light protection.…”

“… MS/MS mass spectra of sunitinib (SUN) ( a ) and N -desethyl SUN ( b ) with chemical structures and identification of the main fragment ions (CE = 30 V); the 238 m/z fragment was obtained with CE = 60 V for both the analytes [ 40 ]. …”
