摘　　要：A sensitive, rapid, simple and economical ultra-performance liquid chromatography-tandem mass spectrometric method （UPLC-MS/MS） was developed and validated for simultaneous determination of imatinib, dasatinib and nilotinib in human plasma using gliquidone as internal standard （IS）. Liquid-liquid extraction method with ethyl acetate was used for sample pre-treatment. The separation was performed on an Xtimate Phenyl column using isocratic mobile phase consisting of A （aqueous phase： 0.15% formic acid and 0.05% ammonium acetate） and B （organic phase： aeetonitrile） （A：B=40：60, v/v）. The flow rate was 0.25 mL/min and the total run time was 6 min. The multiple reaction monitoring （MRM） transitions, m/z 494.5-394.5 for imatinib, 488.7-401.5 for dasatinib, 530.7-289.5 for nilotinib and 528.5-403.4 for IS, were chosen to achieve high selectivity in the simultaneous analyses. The method exhibited great improvement in sensitivity and good linearity over the concentration range of 2.6-5250.0 ng/mL for imatinib, 2.0-490.0 ng/mL for dasatinib, and 2.4-4700.0 ng/mL for nilotinib. The method showed acceptable results on sensitivity, specificity, recovery, precision, accuracy and stability tests. This UPLC-MS/MS assay was successfully used for human plasma samples analysis and no significant differences were found in imatinib steady-state trough concentrations among the SLC22A5 -1889T 〉 C or SLCOIB3 699G 〉 A genotypes （P 〉 0.05）. This validated method can provide support for clinical therapeutic drug monitoring and pharmacokinetic investigations of these three tyrosine kinase inhibitors （TKIs）.A sensitive, rapid, simple and economical ultra-performance liquid chromatography-tandem mass spectrometric method （UPLC-MS/MS） was developed and validated for simultaneous determination of imatinib, dasatinib and nilotinib in human plasma using gliquidone as internal standard （IS）.
