摘要
中药质量标志物是中药质量控制的新概念、新模式,将引领中药质量发展新方向。其中,如何表征中药整体质量属性及其生物学效应,是质量标志物研究的关键科学问题。针对此关键科学问题,本文提出基于整合药理学的中药质量标志物发现与确证的研究思路,即通过"化学指纹-代谢指纹-网络靶标-生物效应-中医功效"多维关联系统筛选候选中药质量标志物,在此基础上,基于"肠吸收-活性评价-数据挖掘"体系建立中药质量标志物与生物活性之间精确定量模型并明确其贡献度。以元胡止痛片和心速宁胶囊为案例,介绍基于整合药理学的中药质量标志物的研究进展。
Quality marker( Q-marker) is a new concept and pattern for quality control of traditional Chinese medicine( TCM),which will lead the development direction for quality control of TCM. Among them,how to characterize the overall quality attribute of TCM and its biological effect,is a critical scientific problem in the study of Q-marker. In this paper,integrated pharmacology is utilized to screen out and confirm the Q-marker from the complex system of TCM,so as to solve the critical scientific problem. System biology in vivo is firstly applied to establish the correlation of chemical fingerprints of TCM,their metabolic fingerprints,network targets,biological effects and efficacy of TCM,which is used to preliminary screen out Q-marker of TCM. Following that,a pharmacological method in vitro,including intestinal absorption in vitro coupled with bioactivity assessment,is employed to simultaneously determine the absorbed doses of TCM and evaluate their biological activity.Furthermore,data mining is utilized to establish the exact quantitative mathematic model between Q-marker of TCM and bioactivity. Meanwhile, two representative examples, including Yuanhu Zhitong tablets, Xinsuning capsules,are introduced to identify Q-marker of TCM and establish their quality standards related with bioactivity,which will be beneficial to improve the level of quality control of TCM and ensure the effectiveness and safety of clinical applications.
