    • 摘要: 探究白木香茶活性成分及治疗糖尿病的作用机制。气相色谱-质谱联用法(GC-MS)分析白木香茶活性成分,利用Swiss Target Prediction数据库收集活性成分对应的靶点、以及GeneCards和OMIM数据库获取糖尿病相关的靶点,将成分靶点与疾病靶点经Venny分析筛选出潜在靶点。通过Cytoscape3.7.1软件构建成分靶点-疾病靶点网络、STRING数据库蛋白质相互作用网络、DAVID数据库对潜在靶点进行基因本体(GO)功能富集分析和基于京都基因与基因组百科全书(KEGG)通路富集分析,利用RCSB PDB数据库和AutoDockTools 1.5.6软件对核心靶点进行分子对接验证。GC-MS法鉴定得到植醇、木栓酮和β-香树酮等23个活性成分;通过数据库收集到372个活性成分靶点与3168个糖尿病相关靶点,筛选出183个白木香茶治疗糖尿病的潜在靶点。这些潜在靶点主要富集于以下功能与通路,生物过程方面有胰岛素受损信号、胰岛素样生长因子受体信号、ERK1和ERK2级联的正调控等;细胞组成方面有质膜、受体复合物、细胞膜等;分子功能方面有跨膜受体、胶原受体的酪氨酸激酶活性、血小板衍生生长因子a受体活性等。KEGG通路分析显示,潜在靶点主要涉及癌症信号通路、胰岛素抵抗通路和内分泌抵抗通路等。分子对接结果表明,核心成分与关键靶蛋白均能稳定结合。综上,白木香茶活性成分通过多成分-多靶点-多通路的方式发挥治疗糖尿病作用,推测白木香茶中α-生育酚、β-香树酮、植醇等活性成分可能通过AKT1、IL-1β、SRC等关键靶蛋白,调节癌症、胰岛素抵抗通路和内分泌抵抗通路等通路,达到治疗糖尿病的作用,为开发糖尿病治疗的天然药物提供了理论依据。

       

      Abstract: This study aimed to explore the active components of Aquilaria sinensis tea and their therapeutic mechanism in diabetes treatment. Gas chromatography-mass spectrometry(GC-MS)was used to analyze the active components. The Swiss Target Prediction database was employed to identify targets corresponding to these components, while diabetes-related targets were collected from the GeneCards and OMIM databases. Potential therapeutic targets were screened using Venny analysis to intersect the component and disease targets. Cytoscape 3.7.1 software was used to construct a component-target-disease network, and the STRING database was applied to build a protein-protein interaction(PPI)network. The DAVID database was utilized for Gene Ontology(GO)functional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analysis of the potential targets. Molecular docking validation of core targets was performed using the RCSB PDB database and AutoDockTools 1.5.6 software. GC-MS analysis identified 23 active components, including phytol, friedelin, and β-amyrin. Database searches yielded 372 active component targets and 3,168 diabetes-related targets, from which 183 potential targets for A. sinensis tea in diabetes treatment were screened. These potential targets were mainly enriched in the following functions and pathways: biological processes such as insulin impairment signaling, insulin-like growth factor receptor signaling, and positive regulation of the ERK1 and ERK2 cascades; cellular components including the plasma membrane, receptor complexes, and cell membrane; and molecular functions such as transmembrane receptor protein tyrosine kinase activity, collagen receptor activity, and platelet-derived growth factor alpha receptor activity. KEGG pathway analysis revealed that the potential targets were primarily involved in pathways related to cancer, insulin resistance, and endocrine resistance. Molecular docking results indicated stable binding between the core components and key target proteins. In conclusion, the active components of A. sinensis tea exert anti-diabetic effects through a multi-component, multi-target, and multi-pathway approach. It is hypothesized that active components such as α-tocopherol, β-amyrin, and phytol may modulate key target proteins including AKT1, IL-1β, and SRC, thereby regulating pathways related to cancer, insulin resistance, and endocrine resistance to achieve therapeutic effects against diabetes. This study provides a theoretical foundation for the development of natural medicines for diabetes treatment.
