This study assessed the anxiolytic and antidepressant activities of a methanol leaves extract of (CV) in Swiss albino mice. The study found a significant increase in the percentage of time spent in the open arms of an elevated plus maze and in the incidence of head dipping in hole-board tests following the administration of 400 mg/kg of CV or 1 mg/kg diazepam. Moreover, a significant ( < 0.001) dose-dependent reduction was observed in the immobility time following CV (200 and 400 mg/kg) and fluoxetine (20 mg/kg) administration for forced swimming and tail suspension tests. Gas chromatography-mass spectroscopy (GC-MS) analysis identified 62 compounds in CV, consisting primarily of phenols, terpenoids, esters, and other organic compounds. A molecular docking study was performed to assess the anxiolytic and antidepressant effects of 45 selected compounds against human serotonin transporter and potassium channels receptors. Network pharmacology was performed to predict the pathways involved in these neuropharmacological effects. Overall, CV demonstrated significant and dose-dependent anxiolytic and antidepressant effects due to the presence of several bioactive phytoconstituents, which should be further explored using more advanced and in-depth mechanistic research.
本研究评估了[植物名称未给出](CV)甲醇叶提取物对瑞士白化小鼠的抗焦虑和抗抑郁活性。研究发现,给予400mg/kg的CV或1mg/kg地西泮后,高架十字迷宫实验中在开放臂停留时间的百分比以及洞板实验中头部探洞发生率均显著增加。此外,在强迫游泳和悬尾实验中,给予CV(200和400mg/kg)和氟西汀(20mg/kg)后,不动时间出现显著(P<0.001)的剂量依赖性降低。气相色谱-质谱联用(GC-MS)分析鉴定出CV中的62种化合物,主要包括酚类、萜类、酯类和其他有机化合物。进行了分子对接研究,以评估45种选定化合物对人血清素转运体和钾通道受体的抗焦虑和抗抑郁作用。开展了网络药理学研究,以预测这些神经药理作用所涉及的途径。总体而言,由于存在多种生物活性植物成分,CV表现出显著的剂量依赖性抗焦虑和抗抑郁作用,应使用更先进和深入的机制研究进一步探索。
