摘要
目的:采用高效液相色谱-串联质谱法(HPLC-MS/MS)建立测定人血浆中尼洛替尼浓度的检测方法。方法:血样经甲醇除蛋白后,流动相分别为0.1%甲酸的甲酸铵缓冲液(A相)和0.1%甲酸的乙腈溶液(B相)梯度洗脱,LunaC_(18)柱(20 mm×2.0 mm,3μm)色谱柱分离,流速为0.6 ml·min^(-1);柱温35℃;电喷雾离子源(ESI),正离子模式,多反应监测,离子对为m/z 530.1→m/z 288.9(尼洛替尼)、m/z 502.3→m/z 394.1(伊马替尼-D8)。结果:尼洛替尼的线性范围为50~10000 ng·ml^(-1),定量下限为50 ng·ml^(-1);日内及日间RSD均小于10%,尼洛替尼低、中、高浓度的提取回收率分别为98.5%,102.4%,103.3%。结论:本检测方法操作简单、灵敏度高、检测下限低、专属性强,适用于临床慢性髓系白血病(CML)患者血浆中尼洛替尼的检测。
Objective:To establish a method for the determination of nilotinib in human plasma by HPLC-MS/MS.Methods:Plasma samples were precipitated by methanol.High performance liquid chromatographic separation was performed on a LunaC_(18) column(20 mm×2.0 mm,3μm)with 0.1%formic acid in both ammonium formate buffer solution and acetonitrile as the mobile phase in a gradient elution manner.The flow rate was 0.6 ml·min-1 and the column temperature was 35℃.Electrospray ionization(ESI)with a positive-ion and multiple reactions monitoring mode was adopted.The ion pairs were m/z 503.1→m/z 288.9 for nilotinib,and m/z 502.3→m/z 394.1 for imatinib-D8.Results:The linear range of nilotinib was 50-10000 ng·ml^(-1),and the lower limit of quantitation was 50 ng·ml^(-1);the intra-and inter-day relative standard deviations were lower than 10%.The extraction recoveries of low,medium and high concentration control samples were 98.5%,102.4%and 103.3%,respectively.Conclusion:The method has the advantages of simplicity,high sensitivity,low detection limit and strong specificity.It is suitable for the determination of nilotinib in chronic myeloid leukemia(CML)patients.
