摘要:

通过网络药理学、分子对接技术结合细胞实验,分析三七总皂苷(Panax notoginseng saponin,PNS)治疗痛风性关节炎(gouty arthritis,GA)的活性成分及作用机制。建立腺苷联合黄嘌呤氧化酶诱导HK-2体外高尿酸细胞模型,研究不同剂量三七总皂苷的降尿酸活性,网络药理学研究进一步分析三七总皂苷治疗痛风性关节炎潜在作用机制,并对关键靶点进行分子对接验证。实验结果表明,三七总皂苷可抑制腺苷联合黄嘌呤氧化酶诱导的肾小管上皮细胞尿酸的释放。从三七总皂苷中筛选出15个干预痛风性关节炎的关键靶点,GO(Gene Ontology,基因本体)和KEGG(Kyoto Encyclopedia of Genes and Genomes,京都基因和基因组百科全书)数据库分析显示三七总皂苷可能通过调控JAK2-STAT3、AGE-RAGE和钙信号传导通路等多个信号通路发挥治疗痛风性关节炎的作用。分子对接结果显示各活性成分与STAT3、PTAFR、IL2等关键靶点的结合能均低于-5 kcal/mol,表明亲和力较好,可作为潜在治疗靶点。该研究为三七总皂苷在痛风性关节炎应用方面提供参考。

Abstract:

In this study,we analyzed the active components and mechanism of Panax notoginseng saponin (PNS) in treatment of gouty arthritis (GA) through network pharmacology,molecular docking,and cellular experiments. An in vitro hyperuricemia cell model was established using adenosine and xanthine oxidase to induce HK-2 cells. Moreover,the uric acid-lowering activity of PNS at different doses was assessed. Network pharmacology was used to explore the potential mechanism of PNS in the treatment of GA,and key targets were validated using molecular docking. Results revealed that PNS could inhibit the release of uric acid from renal tubular epithelial cells that was induced by adenosine and xanthine oxidase. In addition,15 key targets related to GA intervention were identified from PNS. Results of Gene Ontology and Kyoto Encyclopedia of Genes and Genomes analyses suggested that PNS may exert therapeutic effects on GA by regulating multiple signaling pathways,such as JAK2-STAT3,AGE-RAGE,and calcium signaling. The molecular docking results showed that the binding energies of each active component with key targets such as STAT3,PTAFR,and IL2 were all lower than -5 kcal/mol,indicating good affinity,which can be used as potential therapeutic targets. This study provides a reference for the use of PNS in the treatment of GA.
