基于网络药理学的中药复方YA3D6靶向NLRP3/NF-κB通路干预阿尔茨海默病的机制研究
A study on the mechanism of traditional Chinese medicine compound YA3D6 targeting the NLRP3/NF-κB pathway in Alzheimer's disease based on network pharmacology
目的 探讨中药复方YA3D6(人参、黄芪等6味中药)通过抑制NLRP3炎症小体的NF-κB通路干预阿尔茨海默病(Alzheimer's disease, AD)的分子机制。 方法 采用网络药理学方法筛选YA3D6活性成分及作用靶点,构建“成分-靶点-通路”网络;通过分子对接验证其活性成分与NLRP3的结合能力;实验部分优化益生菌发酵工艺,检测入血成分、抗氧化能力及对BV2细胞炎症反应的影响。 结果 网络药理学分析显示,56个核心靶点显著富集于NLRP3/NF-κB通路,核心成分槲皮素等与NLRP3结合能均< -5 kcal/mol。发酵优化后总黄酮含量提升23%,入血成分增加8.2%。体外实验证实,YA3D6-RF抗氧化能力显著优于原型药物,可下调NLRP3表达(P<0.01),促进BV2细胞向M2型极化,改善线粒体结构。 结论 YA3D6通过“双通路抑制”(阻断NF-κB核转位与NLRP3寡聚化)干预AD神经炎症,为开发基于中药复方的AD预防药物提供理论依据。
Objective To investigate the molecular mechanism of traditional Chinese medicine (TCM) compound YA3D6 (six medicinal ingredients including ginseng and astragalus root) in intervening Alzheimer′s disease (AD) by inhibiting the NF-κB pathway of NLRP3 inflammasome via network pharmacology. Methods Network pharmacology was used to screen active components and targets of YA3D6, constructing a "component-target-pathway" network. Molecular docking validated the binding affinity between components and NLRP3. Experimental studies optimized probiotic fermentation processes, analyzed blood-active components, evaluated antioxidant capacity, and tested inflammatory responses in BV2 cell line. Results Network pharmacology identified 56 core targets significantly enriched in NLRP3/NF-κB pathways. Key components such as quercetin showed binding energies<-5 kcal/mol with NLRP3. Fermentation increased total flavonoids by 23% and blood-active components by 8.2%. In vitro experiments demonstrated that YA3D6-RF exhibited superior antioxidant activity, downregulated NLRP3 expression (P<0.01), promoted M2 polarization of BV2 cells, and improved mitochondrial structure. Conclusion YA3D6 intervenes in AD neuroinflammation through "dual-pathway inhibition" (blocking NF-κB nuclear translocation and NLRP3 oligomerization), providing a theoretical basis for developing TCM-based AD preventive drugs.
