[摘要]目的采用网络药理学和分子对接方法研究翅果菊抗抑郁作用的活性成分和作用机制。方法对翅果菊活性成分采用网络药理学方法筛选其作用靶点,并进行富集分析和代谢通路分析,结合分子对接技术进行对接验证。结果在翅果菊18个活性成分中筛选得到2个活性成分,1个作用靶点和7条作用通路,莴苣苷 B 和 guaianolide I 均与γ-氨基丁酸受体亚单位β-3(GABRB3)的11个蛋白受体有良好的结合能力。结论本研究从分子网络层面为翅果菊抗抑郁作用的活性成分和作用机制的深入研究提供了依据和思路。[关键词]翅果菊;抑郁症;网络药理学;分子对接;活性成分;机制

Experimental Education Center of Biology and Basic Medical Science, Sanquan College ofXinxiang Medical University, Henan, Xinxiang 453002, China [Abstract] Objective The network pharmacology and molecular docking were jointly used to study the active ingredients and mechanism for Pterocypselaelata on depression. Methods The targets of ingredients from Pterocypselaelata were screened with network pharmacology. Then, the active targets were analyzed by the enrichment analysis and pathway analysis. At last, the molecular docking method was used to confirm the active molecules and targets. Results In the total 18 compounds of Pterocypselaelata, two active compounds, 1 target and 7 signal pathways were screened by network pharmacology. The molecular docking result showed that both lactuside B and guaianolide I had good binding ability with the 11 protein receptors of Gamma-aminobutyric acid receptor subunit beta-3(GABRB3), respectively. Conclusion This study provides the basis for the antidepressant effect of Pterocypselaelata from the perspective of molecular network, and a foundation for further research the active compounds and mechanism.

作橐桓鲋卮蠊共卫生问题,抑郁症具有高自杀率、高自残率和高复发率的特点。经典的抗抑郁药物起效慢、疗效较差,因此寻找快速、有效和安全的药物用于抑郁症的治疗为当前研究的热点[1-6]。翅果菊(pterocypselaelata)为菊科植物翅果菊Pterocypselaelata ( Hemsl.) Shih 的根或全草。本研究从翅果菊中共分离得到18个活性成分,其中莴苣苷 B(lactuside B,LB)是一种新型化合物,前期药理学研究表明 LB 和翅果菊具有良好的抗抑郁、改善记忆、抗脑缺血和抗心肌缺血作用[7-10]。鉴于此,翅果菊和 LB 在抑郁症的治疗中具有广阔的应用前景,但其作用机制尚不清楚,本研究拟采用网络药理学和分子对接方法研究翅果菊发挥抗抑郁作用的主要活性成分和作用机制。
