结果(1)秦艽-威灵仙药对共检索得到活性成分13个(11种),二者共有活性成分2个;(2)oleanolic acid和lematosideA'_qt是秦艽-威灵仙药对治疗疾病的关键活性成分,此外还有环烯醚萜类化合物、植物甾醇类化合物、皂苷类化合物、环烯醚萜苷类化合物、三萜化合物等成分在药对治疗疾病过程中发挥药效;(3)通过靶点蛋白的相互作用网络分析发现重要靶点55个,degree值排名前五的重要靶点分别为GAPDH、MAPK3、MAPK1、PTGS2和ESR1;(4)活性成分作用靶点与相关疾病网络分析得出药对可以治疗包括类风湿关节炎、肝细胞癌、实验性肝硬化、乳腺癌、前列腺癌和肥胖症等473种疾病;(5)共富集到GO生物过程28条,发现药对活性成分参与机体半乳糖代谢过程、类固醇生物合成过程、胰岛素抵抗过程、氮代谢过程、非小细胞肺癌发生过程、血管平滑肌收缩过程、药物代谢的合成过程等;(6)富集KEGG信号通路:秦艽-威灵仙药对活性成分主要对肿瘤、神经传导、炎症、内分泌等4大类信号通路发挥作用。
结论秦艽-威灵仙药对的活性成分丰富,作用靶点多样,影响通路和生物过程繁杂,对自身免疫疾病、肿瘤、心血管疾病和化学药物损伤等方面的疾病具有较好疗效。

602秦艽为龙胆科植物秦艽(Gentiana macrophylla Pall.)、麻花秦艽(Gentiana straminea Maxim.)、粗茎秦艽(Gentiana cras-si-caulis Duthie ex Burk.)或小秦艽(Gentiana dahurica Fisch.)的干燥根,味辛、苦,性平,入肝、胆、胃经[1]。
《神农本草经》云:“秦艽主寒热邪气,寒湿风痹,肢节痛,下水,利小便”[2]。
由于大部分祛风湿药皆辛燥伤阴,而秦艽药性平和,质地柔润,能祛风湿而不伤阴液,故有“风药中之润剂”之称[3]。
威灵仙为毛莨科植物威灵仙(Clematis chinensis Osbeck)、棉团铁线莲(Clematis hexapetala Pall.)或东北铁线莲(Clematrs mandshusica Rupr)的干燥根及根茎,味辛,性温,入膀胱经,长于祛风湿、止痹痛,主治风湿痹痛、筋骨酸痛、骨骾咽喉等,尤善治风邪偏盛的行痹,医家王肯堂言其为“止痛之要药”[1,4]。
网络药理学以计算机科学、分子生物学、药学等学科为基础,可从整体角度对中药物质基础和药理作用的机制进行现多层次的解析[5-6]。
秦艽和威灵仙是临床常用的祛风湿药,二者所含化学成分极为丰富。
为探讨其活性成分的药理作用,本研究通过网络药理学预测秦艽-威灵仙药对中含有的活性成分及其作用靶点、信号通路和相关疾病等规律,以期从整体角度对秦艽-威灵仙药对的物质基础和药理作用进行多层次解析。
1资料与方法1.1秦艽-威灵仙药对活性成分的筛选依次以“秦艽、威灵仙”为关键词通过TCMSP(http://lsp.nwu.edu.cn/tcmsp.php/)数据库[7]检索各药的成分。
以生物口服利用度(oral bioavailability,OB)≥30%和类药性(drug-likeness,DL)≥0.18作为筛选标准[8]并补充文献报道中常见成分,汇总秦艽-威灵仙药对的活性成分。
1.2活性成分作用靶点的富集与分析将药对活性成分通过PubChem平台(https://pubchem.nc-bi.nlm.nih.gov/)[9]转化为Canonical SMILES标准化学格式后,导入Swiss Target Prediction数据库(http://www.Swiss tar-getprediction.ch/)[10]对活性成分的作用靶点进行统计汇总,最终得到秦艽-威灵仙药对活性成分的作用靶点。
