| 摘要: |
| 目的 利用生物信息学方法及分子对接技术预测温阳振衰颗粒治疗慢性心力衰竭（chronic heart failure，CHF）的活性成分、作用靶点及相关生物学途径。方法 利用TCMSP、BATMAN-TCM数据库筛选温阳振衰颗粒的活性成分及药物潜在靶点，应用GeneCards、PharmGkb、TTD、DrugBank平台检索CHF的疾病靶点，采用Cytoscape 3.7.0软件构建“成分-靶点”网络图，运行STRING平台进行靶蛋白相互作用（protein-protein interaction，PPI）分析，运用R语言数据包进行基因本体功能富集（gene ontology，GO）与京都基因与基因组百科全书（Kyoto encyclopedia of genes and genomics，KEGG）富集分析，预测其作用机制，最后运用AutoDockVina和PyMol软件对温阳振衰颗粒中的关键活性成分与PPI中的核心蛋白进行分子对接验证。结果 共筛选温阳振衰颗粒有效成分145种，涉及靶标238个。“药物-成分-靶点”图中筛选出关键活性化合物204个，其干预的PPI网络主要涉及PTSG2、ESR1、CALM3等核心蛋白，GO及KEGG富集分析结果显示温阳振衰颗粒干预慢性心力衰竭主要涉及氧化应激反应、Ca2+稳态调节、细胞内能量转运等多种生物学途径以及MAPK信号通路、p53信号通路、PI3K-Akt信号通路等相关通路。分子对接验证提示槲皮素与核心靶蛋白JUN结合情况最佳，JUN是温阳振衰颗粒中关键化学成分结合活性最优的靶蛋白。结论 温阳振衰颗粒中槲皮素、豆甾醇、山柰酚等多种关键有效成分可能作用于JUN、MAPK3、STAT3等多种核心靶蛋白，发挥干预CHF的药理作用。 |

| Abstract: |
| Objective Bioinformatics method and molecular docking technology were used to predict the active components, targets and related biological pathways of Wenyang Zhenshuai Granule in the treatment of chronic heart failure (CHF). Methods TCMSP and BATMAN-TCM database were used to screen the active components and potential drug targets of Wenyang Zhenshuai Granule. GeneCards, PharmGkb, TTD and DrugBank platforms were used to search the disease targets of CHF. Cytoscape 3.7.0 software was used to construct the "component-target" network diagram. STRING platform was used to analyze the protein-protein interaction (PPT). R language data package was used to enrich gene ontology (GO) function and Kyoto encyclopedia of genes and genomes (KEGG) to predict its mechanism. AutoDockVina and PyMol software were used to verify the molecular docking of key active components in Wenyang Zhenshuai Granule and core proteins in PPI. Results A total of 145 effective components of Wenyang Zhenshuai Granule were screened, involving 238 targets. A total of 204 key active compounds were screened out from the "drug-component-target" diagram. The PPI network intervened mainly involves core proteins such as PTSG2, ESR1 and CALM3. GO and KEGG enrichment analysis results showed that the intervention of Wenyang Zhenshuai Granule on CHF mainly involved multiple biological pathways such as oxidative stress response, Ca2+ homeostasis regulation, intracellular energy transfer, and MAPK signaling pathway, P53 signaling pathway, PI3K-Akt signaling pathway. Molecular docking verification showed that quercetin had the best binding with the core target protein JUN, and JUN was the target protein with the best binding activity for the key chemical components in Wenyang Zhenshuai Granule. Conclusion Quercetin, stigmasterol, kaempferol and other key active ingredients in Wenyang Zhenshuai Granule may act on JUN, MAPK3, STAT3 and other core target proteins, and play a pharmacological role in the intervention of CHF. |
