龙眼肉化学成分库构建及其治疗贫血机制的网络药理学研究

目的 构建龙眼肉化学成分库，联合网络药理学初步探讨龙眼肉治疗贫血的作用机制。方法 归纳整理近年来关于龙眼肉药效化学成分的文献并构建成分库，通过SwissTargetPrediction预测龙眼肉中活性成分，利用OMIM、DrugBank、GeneCards等数据库收集贫血病症的靶点基因，筛选成分与疾病之间的交集靶点，进行蛋白互作，建立“龙眼肉-活性成分-靶点-疾病”网络，GO富集以及KEGG分析。结果 共收集化合物256种，包括12种糖类、27种多酚类、147种挥发性成分、2种甾醇类、12种有机酸、13种脂类、11种核苷类、29种氨基酸类、3种其他类有机成分以及多种微量元素。筛选后获得活性成分32个；交集靶点24个，TOP1、TERT、MPO、PARP1等可能为关键靶点；生物功能87个，涉及细胞因子介导的信号通路、基因表达的正向调控、细胞因子活性等；通路15个，癌症通路、丝裂原活化蛋白激酶信号通路、碱基切除修复系统等可能为关键通路。结论 本研究建立了龙眼肉化学成分库，基于网络药理学初步探讨龙眼肉治疗贫血的潜在活性成分、靶点信息和作用机制，为龙眼肉的药理药效研究与资源开发提供有价值的参考。

Construction of Chemical Constituents Database of Longan Arillus and Study on Network Pharmacology of Its Mechanism of Treating Anemia

OBJECTIVE To establish the chemical component database of Longan Arillus, and preliminarily explore the mechanism of Longan Arillus in the treatment of anemia combined with network pharmacology. METHODS Summarized and established a database of pharmacodynamic chemical components of Longan Arillus by literature research method. Predicted the active components in Longan Arillus through Swiss TargetPrediction, collected the target genes related to anemia using OMIM, DrugBank, GeneCards, screened the intersection targets between components and diseases, conducted protein interaction, established the "Longan Arillus-active components-target-diseases" network, GO enrichment and KEGG analysis. RESULTS The chemical composition database of Longan Arillus was established and 256 compounds were collected, including 12 saccharides, 27 polyphenols, 147 volatile components, 2 sterols, 12 organic acids, 13 lipids, 11 nucleosides, 29 amino acids, 3 other organic components and various trace elements. The 32 active ingredients were obtained after screening. There were 24 intersection targets, and TOP1, TERT, MPO, PARP1, etc. could be key targets. There were 87 biological functions, involving cytokine mediated signal pathways, positive regulation of gene expression, cytokine activity, etc. There were 15 pathways, including cancer pathway, mitogen activated protein kinase signaling pathway, base excision repair system and so on. CONCLUSION The component library of Longan Arillus has been established. Potential active ingredients, target information and action mechanism of Longan Arillus in the treatment of anemia has been preliminarily discussed. This study can provide a valuable reference for pharmacological and pharmacodynamic research and resource development of Longan Arillus.
