BACKGROUND/AIM: To evaluate acetylcholinesterase (AChE) inhibitory activity and antioxidant capacity of the major molecule from Salvia sp., rosmarinic acid, as a drug candidate molecule for treatment of Alzheimer disease (AD).
MATERIALS AND METHODS
The AChE inhibitory activity of different extracts from Salvia trichoclada, Salvia verticillata, and Salvia fruticosa was determined by the Ellman and isolated guinea pig ileum methods, and the antioxidant capacity was determined with DPPH. The AChE inhibitory activity of the major molecule rosmarinic acid was determined by in silico docking and isolated guinea pig ileum methods.
RESULTS
The methanol extract of Salvia trichoclada showed the highest inhibition on AChE. The same extract and rosmarinic acid showed significant contraction responses on isolated guinea pig ileum. All the extracts and rosmarinic acid showed high radical scavenging capacities. Docking results of rosmarinic acid showed high affinity to the selected target, AChE.
CONCLUSION
In this study in vitro and ex vivo studies and in silico docking research of rosmarinic acid were used simultaneously for the first time. Rosmarinic acid showed promising results in all the methods tested.
背景/目的：评估迷迭香酸（一种来自鼠尾草属植物的主要分子）作为治疗阿尔茨海默病（AD）候选药物分子的乙酰胆碱酯酶（AChE）抑制活性和抗氧化能力。
材料和方法
采用 Ellman 法和分离豚鼠回肠法测定不同提取方法（来自三叶鼠尾草、螺旋鼠尾草和匍匐鼠尾草）对 AChE 的抑制活性，采用 DPPH 法测定抗氧化能力。采用计算机对接和分离豚鼠回肠法测定主要分子迷迭香酸的 AChE 抑制活性。
结果
三叶鼠尾草的甲醇提取物对 AChE 抑制活性最高。相同提取物和迷迭香酸对分离的豚鼠回肠均显示出显著的收缩反应。所有提取物和迷迭香酸均显示出较高的自由基清除能力。迷迭香酸的对接结果表明其对所选靶标 AChE 具有高亲和力。
结论
本研究首次同时应用体外和体内研究以及计算机对接研究迷迭香酸。迷迭香酸在所有测试方法中均表现出良好的效果。
