Description Vincosamide is an alkaloid from Psychotria leiocarpa extract, inhibits the acetylcholinesterase (AChE) activity with anti-inflammatory activity. Vincosamide can effect relaxation of the supercoiled pBR322 plasmid DNA in the presence of Cu2+.
In vitro 化合物vincosamide (PL-1)首次在Psychotria leiocarpa (ME-PL)叶片的甲醇提取物中被鉴定出来,同时发现其对啮齿动物具有抗炎和抗胆碱酯酶效应,并进行了分子对接模拟。通过色谱方法对氯仿部分(CF-PL)的分离,得到了已知化合物PL-1。使用实验模型分析了ME-PL(30、100和300 mg/kg)和PL-1(3、30和100 mg/kg)的抗炎活性,包括爪肿胀、胸膜炎以及由卡拉胶引发的机械和热超敏。ME-PL(30和100 mg/kg)和PL-1(30 mg/kg)的抗胆碱酯酶活性通过抑制脑结构中乙酰胆碱酯酶(AChE)得以显示。分子对接模拟采用Molegro Virtual Docker v6.0进行。总体而言,结果表明ME-PL和PL-1在Cg诱导的爪肿胀、胸膜炎模型中的白细胞迁移以及显著降低机械超敏和对丙酮的冷应答中展示了抗水肿效果。样本在前额皮层中展现了AChE的最大抑制。PL-1与AChE的分子配对在催化位点和外围位点表现出显著的相互作用,证实了抑制试验中所展示的活性。ME-PL的急性给药未在处理的动物中引起毒性迹象。结果显示P. leiocarpa抑制了AChE和抗炎活性,至少部分表明生物碱vincosamide可能是观察到的效应的负责成分,支持了此属植物的民间使用。
