摘要:

目的 使用网络药理学与分子对接技术,探讨墨旱莲-女贞子(EPL-LLA)治疗牙周炎的潜在靶点和分子机制,并通过体外实验探究其生物相容性、对炎症相关因子的调控及抗氧化作用。 方法 通过多种数据库筛选并预测EPL-LLA的活性成分和潜在靶点,将其与牙周炎相关靶点取交集,通过STRING数据库构建蛋白质相互作用网络(PPI)。利用Metascape数据库进行基因本体论(GO)和京都基因与基因组百科全书(KEGG)通路富集分析。将节度点值前6的药物活性成分与通过PPI筛选出的核心靶点进行分子对接,并将结合能较好的结果进行可视化分析。建立体外细胞模型,通过细胞计数试剂盒(CCK-8)、实时定量聚合酶链反应(qRT-PCR)和2,7-二氯二氢荧光素二乙酸酯(DCFH-DA)荧光探针,探究EPL-LLA的生物相容性、对炎症因子的调控作用及抗氧化作用。 结果 经筛选,EPL含有13种活性成分,对应220个潜在靶点;LLA含有10种活性成分,对应283个潜在靶点;牙周炎相关靶点1 643个;三者共有91个交集靶点。交集靶点经GO和KEGG富集分析,共筛选出5 271个条目和253条信号通路。分子对接结果证实节度点值前6的药物活性成分与核心靶点能够较好地结合。CCK-8实验显示浓度在0.02 mg/mL内的EPL-LLA具有良好的生物相容性(P<0.05);qRT-PCR显示EPL-LLA降低牙龈卟啉单胞菌脂多糖(LPS)刺激后巨噬细胞促炎因子mRNA的表达,同时上调抑炎因子mRNA的表达(P<0.05);利用DCFH-DA荧光探针检测证实EPL-LLA具有清除活性氧(ROS)的能力(P<0.05)。 结论 EPL-LLA可通过多成分、多靶点、多通路治疗牙周炎,为进一步研究其对牙周炎的治疗提供了理论依据。

Abstract:

Objective This study aimed to explore the potential target and molecular mechanism of Eclipta prostrata L-Ligustrum Lucidum Ait (EPL-LLA) in the treatment of periodontitis by using network pharmacology and molecular docking technology, and to explore its biocompatibility, regulatory effects on inflammatory factors, and antioxidant acti-vity through in vitro experiments. Methods The active components and potential targets of EPL-LLA were screened and predicted through a variety of databases, and the intersection of EPL-LLA and periodontitis targets was selected. The protein interaction network (PPI) was analyzed by the string platform. The Metascape database was used for gene ontology (GO) and Kyoto encyclopedia of genes and genomes (KEGG) pathway enrichment analysis. The active ingredients from the top 6 degrees were docked with the core targets, and the results of binding energy were visualized. An in vitro cell model was established to evaluate the biocompatibility, modulation of inflammatory factors, and antioxidative effects of EPL-LLA through cell counting kit-8 (CCK-8), quantitative real-time polymerase chain reaction (qRT-PCR) and 2’,7’-Dichlorodihydrofluorescein diacetate (DCFH-DA) fluorescent probe assays. Results Screening revealed 13 active components in EPL corresponding to 220 potential targets, 10 active components in LLA corresponding to 283 potential targets, and 1 643 periodontitis-related targets, with 91 shared targets among the three. GO analysis of the shared targets yielded 5 271 entries, while KEGG enrichment analysis indicated involvement in 253 signaling pathways. Molecular docking confirmed stable binding between the top 6 active components and core targets. CCK-8 assays demonstrated good biocompatibility of EPL-LLA at concentrations 0.02 mg/mL (P<0.05). qRT-PCR showed that EPL-LLA reduced the mRNA expression of pro-inflammatory factors in macrophages stimulated by Porphyromonas gingivalis lipopolysaccharide (LPS) while upregulating anti-inflammatory factor mRNA expression (P<0.05). DCFH-DA fluorescence probe assays confirmed the reactive oxygen species (ROS)-scavenging capacity of EPL-LLA (P<0.05). Conclusion EPL-LLA may treat periodontitis through multi-component, multi-target, and multi-pathway mechanisms, providing a theoretical basis for further research on its therapeutic potential.
