摘要(Abstract):

黄芪为补气之圣药,具有补气升阳,益卫固表的功效。随着黄芪化学成分研究的日益深入,其在临床上的应用也更加广泛。该研究基于系统中药学的理论,从分子层面表征黄芪补气功效,发掘黄芪补气功效标志物。通过TCMSP及ChEMBL数据库构建黄芪有效成分-靶点数据库,明确黄芪补气功效系统所涉及的靶点(元素)。根据靶点间的关系构建蛋白互作网络,并依据分子复合物检测算法(MCODE)划分网络模块(结构),以黄芪发挥补气功效(功能)的药理作用划定其补气功效系统的边界。从成分、靶点、药效层次上探讨表征黄芪补气功效成分。结果表明,黄芪中的常春藤皂苷元、槲皮素、毛蕊异黄酮、刺芒柄花素、华良姜素、异鼠李素、黄芪皂苷Ⅲ、黄芪异黄烷苷等8个关键成分可作用于17个关键靶点构成的8个功能模块,参与G蛋白偶联受体信号通路、脂质代谢过程、氮化合物代谢的正调控、细胞程序性死亡调控、脂肪酸代谢过程的调节等生命过程,产生调节机体免疫功能、强心、保护心肌细胞、改善物质代谢、抗氧化等药理作用,进而发挥补气的功效。该研究基于系统中药学的理论,从分子网络的水平发掘了黄芪补气的功效标志物,为中药药效物质基础阐释及中药质量控制研究提供了新思路。今后可聚焦于这些成分进行配伍研究,进而对黄芪补气功效展开更深入的研究,并加强相应疾病的药理机制及相关制剂的开发。
Astragali Radix is the elixir for invigorating Qi, with the effects of invigorating Qi, promoting Yang and nourishing the body. With the deepening researches on the chemical constituents of Astragali Radix, it is used more extensively in clinical application. Based on systematic traditional Chinese medicine theory, in this paper, we characterized the effect of Astragali Radix on invigo-rating Qi from the molecular level, and explored the markers of Astragali Radix on invigorating Qi. Through TCMSP and ChEMBL databases, the active components-targets database of Astragali Radix was constructed to clarify the targets(elements) involved in Astragali Radix′s Qi invigorating efficacy system. According to the relationship between the targets, the protein interaction network was constructed, and the network modules(structure) were divided according to the theoretic clustering algorithm molecular complex detection(MCODE), and the boundary of the Qi invigorating efficacy system was defined by the pharmacological function of Astragali Radix. The active components of Astragali Radix for invigorating Qi were characterized from the aspects of composition, target and efficacy. The results showed that eight key components of Astragali Radix, such as hederagenin, quercetin, calycosin, formononetin, jaranol, isorhamnetin, astragalosideⅢ, and 9,10-dimethoxypterocarpan-3-O-β-D-glucoside, could act on eight functional modules composed of 17 key targets, and participate in G-protein coupled receptor protein signaling pathway, regulation of lipid metabolic process, positive regulation of nitrogen compound metabolic process, positive regulation of programmed cell death, fatty acid metabolic process and other biological processes to produce pharmacological effects such as regulating immune function, strengthening heart, protecting myocardial cells, improving material metabolism, and antioxidation effects, thus playing the role of invigorating Qi. Based on the systematic Chinese medicine theory, this study explored the effective markers of Astragali Radix at the level of molecular network, which provided new ideas for the interpretation of the effective substance basis of systematic traditional Chinese medicine and the quality control of traditional Chinese medicine. In the future, it can focus on the compatibility research of these components, and then carry out more in-depth studies on the efficacy of Astragali Radix in invigorating Qi, and strengthen the development of the corresponding pharmacological mechanism and related preparations.
