摘要:

文题释义:
丹参酮ⅡA:为唇形科植物丹参的干燥根及根茎,是中药丹参的重要药效活性物质基础之一,属于脂溶性菲醌类化合物,发挥保护心脏和神经、抗癌、抑菌等作用。
分子对接:是通过受体的特征以及受体和药物分子之间的相互作用方式来进行药物设计的方法。主要研究分子间(如配体和受体)相互作用,并预测其结合模式和亲合力的一种理论模拟方法。近年来,分子对接方法已成为计算机辅助药物研究领域的一项重要技术。
背景:丹参酮ⅡA是中药丹参分离得到的最丰富的脂溶性成分之一,发挥保护心脏和神经、抗癌、抑菌等作用,目前还没有系统分析丹参酮ⅡA在血管损伤治疗方面的作用机制研究。
目的:旨在通过生物信息学和分子对接技术系统探索丹参酮ⅡA治疗血管系统损伤的作用机制。
方法:研究利用TCMSP数据库检索丹参酮ⅡA的口服利用吸收度(OB)和类药性(DL),从GEO数据库下载编号GSE85871基因芯片,借助R语言分析其差异基因以获得丹参酮ⅡA的潜在靶点,利用DAVID 6.8数据库对潜在靶点完成GO分析和KEGG通路分析,利用CTD数据库挖掘与丹参酮ⅡA相关的疾病,利用Cytoscape软件构建丹参酮ⅡA的多靶点、多通路、多疾病可视化网络,采用AutoDock Vina进行蛋白与小分子对接验证。
结果与结论:①丹参酮ⅡA的口服利用吸收度值为49.89%、类药性值为0.4,具有良好的药物作用;②筛选出132个潜在靶点,在上述靶点及PPI网络中主要表现在基因共表达和物理互作,潜在靶点生物过程及通路主要富集在卵巢类固醇生成、细胞周期及类固醇激素生物合成等;③丹参酮ⅡA与乳腺肿瘤、高血压、动脉粥样硬化、胶质瘤、血管系统损伤、左室肥厚、白血病及听力损失等疾病治疗相关;④分子对接结果显示丹参酮ⅡA与血红素加氧酶1、分泌型磷蛋白1等血管系统损伤相关蛋白具有较好的结合活性;⑤借助生物信息学手段和分子对接技术能系统地分析丹参酮ⅡA治疗血管系统损伤可能的分子机制与生物学过程,为后续的进一步研究奠定了思路与基础。

Abstract: BACKGROUND: Tanshinone IIA is one of the most abundant fat-soluble components isolated from Radix Salvia miltiorrhiza, which protects the heart and nerves, and exerts anti-cancer and antibacterial effects. There is no systematic study on the mechanism of tanshinone IIA in the treatment of vascular injury.
OBJECTIVE: To explore the mechanism of tanshinone IIA in treating vascular system injury by bioinformatics and molecular docking. 
METHODS: In this study, the oral bioavailability and drug-likeness of tanshinone IIA were searched by TCMSP database, and GSE85871 gene chip was downloaded from GEO database, and the differentially expressed genes were analyzed by R to obtain the potential target of tanshinone IIA. Gene ontology (GO) analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis of potential targets were carried out through DAVID6.8 database. CTD database was used to mine diseases related to tanshinone IIA, and Cytoscape was used to construct multi-target, multi-channel and multi-disease visualization network of tanshinone IIA. AutoDock Vina was used to verify the docking of proteins and small molecules. 
RESULTS AND CONCLUSION: Tanshinone IIA had an oral bioavailability value of 49.89% and a drug-likeness value of 0.4, indicating a good drug effect. A total of 132 potential targets were screened out. Among the above targets and protein-protein interaction networks, they were mainly manifested in gene co-expression and physical interaction. The biological processes and pathways of potential targets were mainly enriched in ovarian steroid production, cell cycle and steroid hormone biosynthesis, etc. Tanshinone IIA was related to the treatments for breast tumors, hypertension, atherosclerosis, glioma, vascular system damage, left ventricular hypertrophy, leukemia, and hearing loss. The molecular docking results show that tanshinone IIA had good binding activity with vascular system damage-related proteins, such as heme oxygenase 1 and secreted phosphoprotein 1. With the help of bioinformatics methods and molecular docking technology, the possible molecular mechanism and biological process of tanshinone IIA in the treatment of vascular system damage can be systematically analyzed, which lays the idea and foundation for further research.
