基于网络药理学方法探讨板蓝根颗粒治疗上呼吸道感染作用机制

Network Pharmacological Studies of Banlangen Granules in Treating Upper Respiratory Tract Infections

目的 :对板蓝根颗粒进行网络药理学的研究,阐明其药效物质基础,进一步探索其药效成分的潜在靶标。方法 :采用包括口服可利用度预测、类药性评估、主成分分析、分子对接模拟以及药效分子-靶标网络的分析等方法于一体的网络药理学模型,研究板蓝根颗粒所含中药组分。结果 :18个主要药效分子与45个治疗上呼吸道感染的靶标具有高网络度,且分子对接计算得出10个关键药效分子与靶标具有较强的结合能,推断其"多组分-多靶点"的方式来发挥治疗上呼吸道感染的作用。结论 :借助网络药理学技术可初步明确板蓝根颗粒治疗上呼吸道感染的药效物质基础及其潜在的分子作用机制。

Objective ：To conduct computing network pharmacological studies on BanlangenGranules,explore its active ingredients in the treatment of upper respiratory tract infections,and further clarify the potential target for its efficacy. Methods ：Oral bioavailability analysis,druggability analysis,principal component analysis,molecular docking and network analysis were applied to study pharmacological properties of compounds of Banlangen Granules on upper respiratory tract infections.Results ：18 principal compounds had high network degree with 45 targets treating upper respiratory tract infections;10 key ingredients and certain special protein had close interactions. Network analysis showed that Banlangen Granules played a significant role in treating upper respiratory tract infections based on the synergistic effect of 10 active ingredients. Conclusion ：The method of network pharmacological studies is helpful to explore possible active molecules in Banlangen Granules and elucidate the mechanism of action.
