  •   Objective   To establish a method and study the pharmacokinetics for concentration determination of effective components in Xiakucao Xiaoliu mixture in Normal Rat Plasma By LC-MS/MS.   Methods  The mobile phase was methanol-water (0.1% formic acid) system under the positive ion mode of C18 chromatographic column, gradient elution was adopted, and the flow rate was 0.3 ml/min. In the negative ion mode, the mobile phase was acetonitrile-water (0.1% formic acid) system, gradient elution, with a flow rate of 0.4 ml/min. Caffeic acid, rosmarinic acid, syringic acid, rutin in positive ion mode and Atractylodes lactone II and Atractylodes lactone III in negative ion mode were respectively determined. Normal rats were intragastrically given Xiakucao Xiaoliu Mixture 7.8 ml/kg, and blood was taken from the orbit at different time points after the administration. The blood concentration was determined by the validated LC-MS/MS method and the non-standard DAS2.0 software was used. The pharmacokinetic parameters of rats after administration were calculated by the compartment model.   Results   The pharmacokinetic parameters belonged to non atrioventricular model. The pharmacokinetic characteristics of the four main anti-cancer active ingredients of Caffeic acid, Rosmarinic acid, Syringic acid and Atractylodes Ⅲ in rats after administration of Xiakucao Xiaoliu Mixture were significantly different from those reported in the literature after the administration of monomers.   Conclusion  The established method was simple, accurate and sensitive, which could be suitable for the content determination of effective components in Xiakucao Xiaoliu mixture in Normal Rat Plasma, which would be a valuable information for the study on main anticancer active substances.

  • 夏枯草消瘤合剂源于著名中医肿瘤学专家钱伯文教授的经验方，是上海中医药大学附属岳阳中西医结合医院用于肿瘤治疗的特色院内制剂（批准文号：沪药制字Z05050340），已在临床应用30余年，对于肺癌、肝癌、甲状腺癌等癌症治疗效果显著，现已成为医院肿瘤内科的一线用药。该方由夏枯草、生地黄、牡蛎、煅牡蛎、莪术、麸炒白术、麸炒苍术等七味药组成，具有化痰、散结、解毒的功效[1-2]。

    课题组前期采用高效液相色谱-飞行时间串联质谱（HPLC-TOF/MS）对夏枯草消瘤合剂中的37种主要药效成分进行了定性鉴别[3]。通过文献检索，明确夏枯草消瘤合剂中主要含有咖啡酸[4-6]、迷迭香酸[7-9]、丁香酸[10-12]、芦丁[13-15]、白术内酯Ⅱ[16-18]、白术内酯Ⅲ[19-20]等多种具有抗肺癌药理作用的活性成分。尽管夏枯草消瘤合剂临床疗效显著，抗癌活性成分明确，但作用机制尚不明确，因此，对夏枯草消瘤合剂开展体内药动学研究十分有必要。

    笔者采用超高效液相色谱-串联质谱（UPLC-MS/MS）分析技术，利用正常大鼠，经口灌胃给药，对夏枯草消瘤合剂中6种主要的抗癌活性成分进行体内药动学研究，为其临床合理用药评价提供必要的科学支持。

    3.   讨论

    • 本次实验采用单次灌胃给予夏枯草消瘤合剂，给药后不同时间点眼眶取血，利用LC-MS/MS检测合剂中主要药效成分（包括咖啡酸、迷迭香酸、丁香酸、白术内脂Ⅲ等）的血药浓度，并绘制“药-时曲线”，结果呈现出典型的血管外给药特征。其中，咖啡酸和迷迭香酸在大鼠体内代谢的半衰期及达峰时间较两种成分单独代谢均显著延长[21]，表明复方配伍可以减缓咖啡酸和迷迭香酸在大鼠体内代谢速度，延长两者在体内发挥作用的时间，起到了增加疗效的作用。其中，咖啡酸为迷迭香酸的代谢产物[22]，合剂中咖啡酸半衰期及达峰时间的延长可能与迷迭香酸等酚酸类成分的代谢相关，迷迭香酸的代谢造成了体内咖啡酸的总量增加，间接造成了咖啡酸“在体内拥有更长的滞留时间及进入血液循环更高的药物浓度”的表象。此外，丁香酸的药时曲线出现双峰，而此前未有文献报道此类情况，原因有待进一步研究。白术内酯III在复方中代谢与其单独代谢时相比达峰时间明显缩短[23]，可能是复方中的成分影响体内代谢酶活性，进而促进了白术内酯III的代谢。

      本研究结果显示，合剂中各成分的代谢均存在显著性别差异。咖啡酸在雌性与雄性大鼠体内暴露的AUC值具有2倍的差异，且雌性相较于雄性到达tmax（峰浓度时间）有30 min延迟，提示雌雄个体间药物进入血液循环的相对量及达峰时间存在明显的差异。同样，白术内酯Ⅲ的性别差异也极为明显，AUC存在约10倍的差异，MRT、t1/2、cmax存在4倍差异，提示白术内酯Ⅲ在雌性体内仍发挥药效的同时在雄性大鼠体内早已被清除。现有研究证实[24-25]，大鼠药动学的性别差异主要原因是雌性与雄性大鼠肝中CYP450酶的种类差异。大鼠与人类的CYP450酶系在酶的组成和活性上亦存在明显差异[26]。

      在夏枯草消瘤合剂用于临床治疗非小细胞肺癌的合理用药方案制订、与化疗药物等相互作用评价、药物本身体内代谢过程监测及根据患者性别不同的个体差异化给药方案调整等过程中，本次实验的研究结果将为中药临床药动学方面的评估提供科学依据。
