摘 要 目的 建立测定德拉马尼(DLM)血药浓度的方法并应用。方法 血浆样品经甲醇沉淀蛋白后,采用超高效液相色谱-串联
质谱(LC-MS/MS)法检测。色谱柱为Phenomenex Synergi Fusion-RP,流动相为甲醇-0.1%甲酸溶液(梯度洗脱),柱温为40 ℃,流

速为 0.3 mL/min,进样量为 1 μL;离子源为电喷雾离子源,以多反应监测模式进行正离子扫描,用于定量分析的 DLM 离子对
为 m/z 535.0→352.0。采用上述LC-MS/MS法测定6例耐多药结核病(MDR-TB)患者体内DLM的血药浓度。结果 DLM检测质
量浓度的线性范围为0.05~8 μg/mL(r=0.999 5),定量下限为0.05 μg/mL;日内、日间精密度RSD均小于10%,准确度为92.7%~
104.9%,平均基质效应为 94.3%~107.5%,平均萃取回收率为 93.2%~98.1%。6 例 MDR-TB 患者体内 DLM 的血药浓度为 0.61~
2.76 μg/mL,平均(1.67±0.74)μg/mL。结论 所建LC-MS/MS法专属性好,灵敏度、准确度及精密度均高,可用于MDR-TB患者体
内DLM血药浓度的检测。

ABSTRACT OBJECTIVE To establish and apply a method for the determination of plasma concentration of delamanid (DLM).
METHODS After plasma samples were treated with methanol precipitation, LC-MS/MS was adopted to determine the plasma
concentration of DLM. The chromatographic column was Phenomenex Synergi Fusion-RP with mobile phase of methanol-0.1%
TM
formic acid solution (gradient elution). The column temperature was 40 ℃, the flow rate was 0.3 mL/min, and the sample size
was 1 μL. The ion source was electrospray ion source, and positive ion scanning was carried out in multi-reaction monitoring
mode. The DLM ion pair used for quantitative analysis was m/z 535.0→352.0. The plasma concentration of DLM in 6 multidrug
resistant tuberculosis (MDR-TB) patients were determined by the LC-MS/MS method. RESULTS The linear range of DLM was
0.05-8 μg/mL (r=0.999 5), and the lowest limit of quantitation was 0.05 μg/mL. RSDs of intra-batch and inter-batch precision
were all less than 10%. The accuracy ranged 92.7%-104.9%. Average matrix effect was 94.3%-107.5%. Average recoveries were
93.2%-98.1%. The plasma concentration of DLM in 6 MDR-TB patients ranged from 0.61-2.76 μg/mL, with an average of (1.67±
0.74) μg/mL. CONCLUSIONS The established LC-MS/MS analysis method has good specificity, high sensitivity, accuracy and
precision, and can be used to determine DLM plasma concentration in MDR-TB patients.
