OBJECTIVE To establish a liquid chromatography tandem mass spectrometry (LC-MS/MS) method for determination of cinnamic acid (CA), vanillic acid (VA) and 3,3'-O-dimethylellagic acid (DMA) concentrations in rat plasma and evaluate the pharmacokinetics and the correlations between dose and systemic exposure levels of CA, VA and DMA in rats after single dose administration of Anshen Buxin Liuwei Pills (ASBX). METHODS Blood was collected from male SD rats at different time points after different dose administration. The plasma was processed by protein precipitation method. The concentrations of CA, VA and DMA in plasma were determined by LC-MS/MS method. Pharmacokinetic parameters were calculated with MaS Studio software. The correlations between dose and systemic exposure level were analyzed by confidence interval method. RESULTS The linear relationship of the calibration curves of the three compounds were good within the tested ranges, and the specificity, precision and accuracy, recovery, matrix effect and stability of the method all met the requirements for biological sample assay. After single intragastric administration of ASBX, the tmax of CA, VA and DMA were 0.22-0.40, 0.08 and 5.40-8.20 h, the t1/2 were 0.79-2.04, 0.37-0.65 and 4.26-9.58 h, the ρmax were 279.70-302.88, 16.42-43.33, and 2.81-7.20 ng·mL-1, and the AUC0-∞ were 351.83-537.96, 7.20-18.82, and 29.27-119.64 ng·h·mL-1, respectively. The results of confidence interval analysis showed that the ρmax and AUC of VA and DMA, and AUC of CA were positively correlated with dose, but the ρmax of CA was not clearly correlated with dose. CONCLUSION The LC-MS/MS analysis method is proved to be rapid, sensitive, and accurate, so it can be applied to the pharmacokinetic study of ASBX after intragastric administration in rats. This sdtudy provides a reference for future research on the pharmacodynamic material basis and safe and effective clinical use of ASBX.

目的 建立大鼠血浆中肉桂酸(cinnamic acid,CA)、香草酸(vanillic acid,VA)和3,3'-O-二甲基鞣花酸(3,3'-O-dimethylellagic acid,DMA)浓度测定的液相色谱-串联质谱联用(LC-MS/MS)分析方法,研究给药不同剂量安神补心六味丸(Anshen Buxin Liuwei Pills,ASBX)后3种成分的药动学过程及量暴关系。方法 雄性SD大鼠灌胃给药不同剂量ASBX后采集不同时间点血浆并采用蛋白沉淀法处理,采用LC-MS/MS法测定血浆中CA、VA和DMA的浓度,用MaS Studio软件计算药动学参数,采用置信区间法分析给药剂量和系统暴露水平的相关性。结果 在线性范围内3种化合物线性关系良好,该方法专属性、精密度与准确度、回收率、基质效应和稳定性均满足生物样品的测定要求。大鼠单次灌胃给药ASBX后,CA、VA和DMA的tmax分别为0.22~0.40、0.08和5.40~8.20 h,t1/2分别为在0.79~2.04、0.37~0.65和4.26~9.58 h,ρmax分别为279.70~302.88、16.42~43.33、2.81~7.20 ng·mL-1,AUC0-∞分别为351.83~537.96、7.20~18.82、29.27~119.64 ng·h·mL-1。随着给药剂量的增加,VA和DMA在大鼠体内的ρmax和AUC,以及CA的AUC均与剂量呈正相关,但是CA的ρmax则与剂量无明确相关性。结论 该分析方法快速、灵敏、准确,适合大鼠灌胃给药ASBX后的药动学研究,为其药效物质基础研究和临床安全有效用药提供了参考。

OBJECTIVE To establish a liquid chromatography tandem mass spectrometry (LC-MS/MS) method for determination of cinnamic acid (CA), vanillic acid (VA) and 3,3'-O-dimethylellagic acid (DMA) concentrations in rat plasma and evaluate the pharmacokinetics and the correlations between dose and systemic exposure levels of CA, VA and DMA in rats after single dose administration of Anshen Buxin Liuwei Pills (ASBX). METHODS Blood was collected from male SD rats at different time points after different dose administration. The plasma was processed by protein precipitation method. The concentrations of CA, VA and DMA in plasma were determined by LC-MS/MS method. Pharmacokinetic parameters were calculated with MaS Studio software. The correlations between dose and systemic exposure level were analyzed by confidence interval method. RESULTS The linear relationship of the calibration curves of the three compounds were good within the tested ranges, and the specificity, precision and accuracy, recovery, matrix effect and stability of the method all met the requirements for biological sample assay. After single intragastric administration of ASBX, the tmax of CA, VA and DMA were 0.22-0.40, 0.08 and 5.40-8.20 h, the t1/2 were 0.79-2.04, 0.37-0.65 and 4.26-9.58 h, the ρmax were 279.70-302.88, 16.42-43.33, and 2.81-7.20 ng·mL-1, and the AUC0-∞ were 351.83-537.96, 7.20-18.82, and 29.27-119.64 ng·h·mL-1, respectively. The results of confidence interval analysis showed that the ρmax and AUC of VA and DMA, and AUC of CA were positively correlated with dose, but the ρmax of CA was not clearly correlated with dose. CONCLUSION The LC-MS/MS analysis method is proved to be rapid, sensitive, and accurate, so it can be applied to the pharmacokinetic study of ASBX after intragastric administration in rats. This sdtudy provides a reference for future research on the pharmacodynamic material basis and safe and effective clinical use of ASBX.

安神补心六味丸(Anshen Buxin Liuwei Pills,ASBX)(吉如和-6)是蒙医药经典复方制剂,由牛心、木香、肉豆蔻、丁香、枫香脂、广枣等6味药材组成,具祛“赫依”、镇静、养血安神之功效,临床上多用于治疗冠心病、心绞痛、心律失常等[1-3],也可用于治疗肝郁气滞所致的心烦、焦虑、失眠、健忘等[4-5]。方中牛心为主药,补心、止痛;广枣强心、镇静;肉豆蔻镇心赫依;丁香抑制主脉“赫依”;枫香脂燥希拉乌素、止痛;佐木香调理赫依血不和[6]。研究表明,有机酸类对大鼠心肌缺血再灌注损伤具有保护作用[7-8],而ASBX中含有包括肉桂酸(cinnamic acid,CA)、香草酸(vanillic acid,VA)和3,3'-O-二甲基鞣花酸(3,3'-O-dimethylellagic acid,DMA)等在内的多种有机酸类化合物[9]。有研究显示,CA预处理后能够减少大鼠的心肌缺血再灌注损伤,起到保护心肌功能的作用[10-11],VA具有较强的抗氧化活性,可通过减少丙二醛含量和增强超氧化物歧化酶、过氧化氢酶等内源性抗氧化酶的作用,发挥保护心肌的作用[12-13]。DMA具有一定的抗氧化性,文献[14]通过DPPH自由基和CCl4诱导的脂质过氧化实验发现DMA通过发挥其抗氧化性而起到保护肝脏的作用。因此,有必要对给药ASBX后血浆中3种有机酸进行定量研究,为ASBX的药效物质研究提供数据支撑。
中药药动学研究在中药研究与开发过程中发挥着连接化学、药理和临床等学科的作用,是研究中药体内多组分、多靶点药效物质基础和安全性等研究的重要环节[15-18]。目前对ASBX的药动学研究主要涉及单体成分给药后,或者含有某味药材的其他复方制剂给药后动物体内的药动学研究[19-21],未见有给药ASBX后相关成分在动物体内药动学研究的报道。给药剂量和系统暴露水平相关性研究可以反映发挥药效或者引起毒副作用的药物成分与给药剂量之间的关系,为中药安全、有效用药提供指导[22-23]。本课题组从6只给药ASBX后大鼠的血清中共鉴定到17种共有成分,其中包括CA、VA和DMA等有机酸,以及其他5种不同类型的成分能够进行定量分析,考虑到各成分的化学性质不同,本实验采用高效液相串联质谱(HPLC-MS/MS)建立了同时测定大鼠血浆中CA、VA和DMA的方法,对不同剂量灌胃给药ASBX后大鼠血浆中3种成分的浓度进行分析,获得了单次不同剂量给药后的药动学特征,并分析了给药剂量和系统暴露水平的相关性,为蒙药ASBX的物质基础研究,以及临床安全有效用药提供数据支撑。

大鼠按体质量随机分为3组,包括ASBX低(0.54 g·kg-1)、中(1.08 g·kg-1)和高(2.16 g·kg-1)剂量组,每组5只雄性大鼠。称取ASBX适量,加入适量0.5% CMC-Na,超声溶解,配制成质量浓度分别为0.054、0.108、0.216 g·mL-1的ASBX药液,按10 mL·kg-1灌胃给药,各组分别在给药前(0 min)、给药后0.083、0.25、0.5、0.75、1、2、3、5、7、9、11和24 h后,大鼠在麻醉状态下眼眶静脉丛采血约150 μL,置1.5 mL肝素抗凝的离心管中,于4 ℃,10 000 r·min-1离心2 min,转移血浆,-80 ℃冰箱冷冻保存。
采用已建立的LC-MS/MS分析方法对血浆样品进行定量分析,以血药浓度为纵坐标,时间为横坐标,获得ASBX各给药组大鼠血浆中3种主要成分的平均血药浓度-时间曲线。采用MaS Studio 1.5.2.14软件非房室模型计算CA、VA、DMA在大鼠体内的等药动学参数,应用Microsoft Excel处理数据,实验数据用平均值±标准差($\stackrel{-}{x}$±s)表示。
大鼠单次给药不同剂量的ASBX后,CA、VA、DMA均在5 min吸收入血。CA达峰迅速,平均达峰时间(tmax)在0.22~0.40 h之间,VA达峰最快tmax为0.08 h,DMA达峰较慢,tmax在5.40~8.20 h之间;CA的平均半衰期(t1/2)在0.79~2.04 h之间,平均滞留时间(MRT)在1.26~3.00 h之间,VA的t1/2在0.37~0.65 h之间,MRT在0.48~0.92 h之间,DMA的t1/2在4.26~9.58 h之间,MRT在8.90~16.74 h之间。
CA在大鼠体内的暴露水平最高,低、中、高剂量给药后其在体内的平均峰浓度(ρmax)分别为(279.70±113.86) (302.88±113.79)(283.65±175.59) ng·mL-1,平均曲线下面积(AUC0-∞)分别为(351.83±115.01) (479.1±157.62) (537.96±324.86) ng·h·mL-1,VA在大鼠体内的暴露水平低于CA,其ρmax分别为(16.42±5.07) (36.68±40.30) (43.33±18.70) ng·mL-1,AUC0-∞分别为(7.20±3.77) (10.83±7.49) (18.82±8.92) ng·h·mL-1,DMA在大鼠体内的暴露水平最低,其ρmax分别为(2.81±2.75) (4.98±1.82) (7.20±1.54) ng·mL-1,AUC0-∞分别为(29.27±28.51)、(91.76±18.45) (119.64±38.75) ng·h·mL-1。药动学参数见表4,平均血药浓度-时间曲线图见图4
采用置信区间法[24-25]对3个化合物的系统暴露水平(ρmax和AUC)与剂量进行相关性分析,结果见表5,拟合曲线见图5。CA的ρmax与剂量之间无明确相关性,AUC0-∞与剂量呈正相关,为非线性相关;VA的ρmax与剂量成正相关,为非线性相关,AUC0-∞与剂量成正相关,但是线性关系不确定;DMA的ρmax与剂量成正相关,为非线性相关,AUC0-∞与剂量成正相关,但是线性关系不确定。
本研究开展前采用高效液相色谱-四极杆飞行时间串联质谱(HPLC-Q-TOF-MS/MS)技术解析了给药ASBX后大鼠血清中的化学成分,血清样品中共鉴定到109个药物成分,其中17种成分为6只给药大鼠血清中的共有成分。之后通过药动学预实验发现临床等效剂量给药后,大鼠血浆中能够定量的成分包括CA、VA和DMA等有机酸,以及其他5种不同类型的成分,考虑到各成分的化学性质不同,本课题组开发了不同的LC-MS/MS分析方法。
本研究建立了同时测定大鼠血浆中CA、VA和DMA等有机酸的LC-MS/MS方法。采用此方法分析了不同剂量灌胃给药ASBX后大鼠血浆中3种成分的浓度,系统考察了3种成分的药动学特征,明确了给药剂量和3种成分系统暴露水平的相关性,为蒙药ASBX药效物质基础的研究提供了参考。但是ASBX作为一个复方,组成复杂,还需要在后续研究中对其他成分(类型)的药动学特征进行考察。
血浆样品中有机酸类的处理方法有液-液萃取法和蛋白沉淀法等[26-27]。本研究比较了甲醇、乙腈、丙酮、乙酸乙酯、二氯甲烷等不同蛋白沉淀试剂和萃取试剂,结果发现采用丙酮进行蛋白沉淀时3种成分的提取回收率均为最高。
ASBX每日临床最大服用生药量6 g,按成人平均体质量60 kg计算,为0.1 g·kg-1,按体表面积换算成大鼠等效剂量(生药量)为0.54 g·kg-1。药动学研究结果表明,低、中、高剂量给药ASBX后,CA、VA和DMA在体内的ρmax,以及肉桂酸AUC的高低与ASBX中3种成分的含量高低保持一致,而VA和DMA的AUC则与二者的含量呈现出相反的结果,可能是由于二者的结构存在差异(VA为小分子的酚酸类化合物,DMA为多酚二内酯类化合物)而引起了大鼠体内代谢的不同。
大鼠灌胃给药ASBX后CA的tmax比文献[28-29]报道的长,而t1/2则基本一致,而复方给药后与单独灌胃CA[30]tmaxt1/2均有所差异说明复方中的其他成分对CA的吸收和代谢均产生了不同程度的影响。VA在大鼠体内吸收最快(tmax为5 min),而且代谢也较快,与文献[31-32]报道的(t1/2在3.74~8.89 h之间,MRT在3.15~4.45 h之间)有差别,可能是在ASBX处方中存在药物之间的相互作用,加快了VA在大鼠体内的吸收和代谢。目前暂无DMA药动学方面的相关报道,本研究的结果显示其吸收(tmax在5.40~8.20 h)和代谢(t1/2在4.26~9.58 h之间, MRT在8.90~16.74 h之间)均较慢,是否会引起体内蓄积需要进一步的实验验证。
给药剂量和系统暴露水平相关性研究结果表明,随着ASBX给药剂量的增加,VA和DMA在大鼠体内的ρmax和AUC,以及CA的AUC均随着剂量的增加而增加,但是CA的ρmax并未呈现出增加的趋势,可能是由于当药物浓度达到某一限度时,体内的代谢酶或者载体的运输能力会达到饱和,从而表现出不同给药剂量下吸收相同的结果[33]
