中文摘要
中药复方配伍的药代动力学研究是中药现代研究的关键问题。痹祺胶囊作为临床治疗风湿痹症等慢性疾病的传世验方,但未见对其药代动力学研究报道。在中药复方君臣佐使配伍理论的指导下,以君药主要效应成分士的宁和马钱子碱为主线,首次建立了生物样品中士的宁和马钱子碱的定量分析方法。发现痹祺胶囊复方中除君药外的其他配伍组分影响了士的宁和马钱子碱在大鼠体内的药动学行为,并且差异主要体现在吸收过程;臣药组和佐药组均能显著延长士的宁和马钱子碱的达峰时间,吸收过程的改变是痹祺胶囊可以体现对中枢系统增效减毒作用,该臣、佐、使药相互作用对君药药动学的影响,体现痹祺胶囊复方配伍的科学性。所建立的药物代谢研究技术平台具有良好的适用性,为痹祺胶囊各组分代谢研究提供坚实基础。用计算模拟的方法对可能的产物结构以及代谢位点进行计算,发现氮杂双环上的氮是最有可能的代谢位点,为进一步考察马钱子碱代谢产物活性变化提供了基础数据。本项目整合体内外药代方法、生物信息学方法与系统生物学方法,以整体的观点出发建立中药药代动力学的实验和预测系统,提出具有创新理念的三维研究模式、技术路线和中药药代动力学的实验和预测系统,具有明显创新性。
英文摘要
The key issue of modernization of Chinese medicine is the pharmacokinetic study of compatibility of traditional Chinese medicine. Biq capsule has been proven to be effective for chronic diseases treatment, for example, arthritis; however, no pharmacokinetic study was reported in literature. Under the guidance of principle of compatibility of Chinese medicine, LC-MS quantitative determination of strychine and brucine, the two principal components, in biological sample established provided powerful analysis approach for pharmacokinetic study. The results indicated that the pharmacokinetic behaviors of strychine and brucine in rats were affected by other components existing in the Biqi capsule, in particular, in the course of absorption. tmax of strychine and brucine were postponed, the toxic effects of both components were alleviated; the effects of drug-drug interactions of multi components on pharmacokinetics of principal components was illustrated for the first time, indicating that rationality of compatibility of multi components of Biqi capsule. In addition, no significant time-dependent inhibition on 7 main subtypes of P450 enzymes was observed. The structure of possible products and metabolic site was calculated by computational simulation approach, the nitrogen atom on nitrogen-hybrid rings was proposed to
