摘要(Abstract):

活血中药和理气中药,二者在中医临床上常常配伍使用,然而2类中药功效发挥作用的机制尚不清晰。中药靶标活性谱是能够标示中药活性成分及其作用靶标、作用强度的图谱,可用于中药功效作用机制的探索。该研究基于中药成分数据库获得常用活血中药集、理气中药集及非活血、理气的阴性集化学成分。通过活血中药化学成分与DrugBank数据库中化学成分的相似度分析获得活血中药化学成分预测靶标,以两者的相似值作为活血中药化学成分与预测靶点的活性值,进而对成分-靶标活性值赋予权重。将每味中药作用于同一靶点的活性值进行融合,分别构建活血、理气、阴性中药靶标活性谱。选取活血、理气中药作用活性值大于阴性中药的靶点作为功效潜在作用靶点,分别构建蛋白-蛋白相互作用网络,进行拓扑、GO、KEGG富集分析,确定活血、理气功效的关键靶点。结果显示,基于DrugBank数据库收集获得成分-靶点活性信息,共包含4 499个化合物、627个靶点及11 295条作用关系。活血功效蛋白-蛋白相互作用网络包含206个节点和1 728条边,理气功效蛋白-蛋白相互作用网络包含230个节点和986条边。通过拓扑、GO、KEGG富集分析发现,活血中药主要通过作用于VEGF/VEGFR2介导的信号级联通路、ERK信号通路、钙信号通路、PI3K-AKT信号通路发挥抗炎、神经保护、血管生成等药效进而产生活血功效,关键靶点为丝裂原活化蛋白激酶3(mitogen activated protein kinases 3,MAPK3)、原癌基因酪氨酸蛋白激酶(proto-oncogene tyrosine-protein kinase Src,SRC)、丝裂原活化蛋白激酶1(mitogen activated protein kinases 1,MAPK1)、人表皮生长因子受体(epidermal growth factor receptor,EGFR)、磷脂酰肌醇-3-激酶亚基α(phosphatidylinositol 4,5-bisphosphate 3-kinase catalytic subunit alpha isoform,PIK3CA)、过氧化物酶体增殖物激活受体(peroxisome proliferators-activated receptor gamma,PPARG)、内皮型一氧化氮合酶(nitric oxide synthase 3,NOS3)、前列腺素G/H合成酶2(prostaglandin G/h synthetase 2,PTGS2)、基质金属蛋白酶9(matrix metalloproteinase-9,MMP9)、血管内皮细胞生长因子A(vascular endothelial growth factor A,VEGFA)。理气中药主要通过作用于MAPK信号通路、PI3K-AKT信号通路发挥抗炎、神经保护等药效进而产生理气功效,关键靶点为丝裂原活化蛋白激酶8(mitogen activated protein kinases 8,MAPK8)、SRC、丝裂原活化蛋白激酶14(mitogen activated protein kinases 14,MAPK14)、PIK3CD、EGFR、RAC-α丝氨酸/苏氨酸-蛋白激酶(RAC-alpha serine/threonine-protein kinase,AKT1)、丝裂原活化蛋白激酶3(mitogen activated protein kinases 3,MAPK3)。研究基于靶标活性谱进行了理气、活血功效的靶点分析,为中药功效靶标研究提供了借鉴,也为临床应用提供一定的科学依据。
The traditional Chinese medicines(TCM) for activating blood circulation and the TCM for regulating Qi are often used in combination in clinical practice. However, their mechanisms are still unclear. The activity spectrum of targets can fuse the active components, targets and intensity of action, which provides support for the discussion of efficacy targets. The chemical components of common TCM sets for activating blood circulation and regulating Qi, as well as the negative sets not for activating blood circulation and re-gulating Qi were obtained from the database of TCM. By the similarity analysis of chemical components in TCM for activating blood circulation and DrugBank database, the predicted targets of chemical components in TCM for activating blood circulation were obtained, and the similarity value of the two was taken as the activity value of the active components and predicted targets. Then, the component-target activity value was weighted. The activity values of herb acting on the same target were fused to construct activity spectra of targets of the herbs for activating blood circulation, herbs for regulating Qi and negative herbs. The targets whose activity values of activating blood circulation and regulating Qi were higher than those of negative herbs were selected as potential targets of efficacy. Protein-protein interaction networks were constructed for topological, GO and KEGG enrichment analysis to determine the key targets of efficacy of activating blood circulation and regulating Qi. The component-target activity information collected from DrugBank database contained 4 499 compounds, 627 targets and 11 295 action relationships. The activating blood function protein-protein interaction network contained 206 nodes and 1 728 edges, while the regulating Qi function protein-protein interaction network contained 230 nodes and 986 edges. The enrichment analysis of topology, GO and KEGG showed that TCM for activating blood circulation mainly exerted its anti-inflammatory, neuroprotective and angiogenic effects on signaling cascade pathway mediated by VEGF/VEGFR2, ERK signaling pathway, calcium signaling pathway and PI3 K-AKT signaling pathway, and the key targets included mitogen activated protein kinases 3(MAPK3), proto-oncogene tyrosine-protein kinase Src(SRC), mitogen activated protein kinases 1(MAPK1), epidermal growth factor receptor(EGFR), phosphatidylinositol 4,5-bisphosphate 3-kinase catalytic subunit alpha isoform(PIK3 CA), peroxisome proliferators-activated receptor gamma(PPARG), nitric oxide synthase 3(NOS3), prostaglandin G/H synthetase 2(PTGS2), matrix metalloproteinase-9(MMP9), and vascular endothelial growth factor A(VEGFA). TCM for regulating Qi mainly exerted anti-inflammatory and neuroprotective effects by acting on MAPK signaling pathway and PI3 K-AKT signaling pathway, and the key targets included mitogen activated protein kinases 8(MAPK8), SRC, mitogen activated protein kinases 14(MAPK14), and RAC-alpha serine/threonine-protein kinase(AKT1), mitogen activated protein kinases 3(MAPK3). Based on the activity spectrum of targets, the targets of the TCM for activating blood and the targets of the TCM for regulating Qi were analyzed to provide reference for the study of efficacy targets of TCM, and also provide some scientific basis for clinical application.
