Biological Activity | (-)-Huperzine A是从中国草药Huperzia serrata分离出的一种新型的生物碱。(-)-Huperzine A (HupA)是一种有效的,高度特异性的,可逆acetylcholinesterase (AChE)(乙酰胆碱酯酶)抑制剂,Ki为7 nM,作用于G4 AChE比作用于G1 AChE选择性高200倍。(-)-Huperzine A 也是 N-甲基-D-天冬氨酸 (NMDA) 受体的非竞争性拮抗剂。(-)-Huperzine A 被用于神经退行性疾病的研究,包括阿尔茨海默病。[1-4] |
IC50 | 82nM(AChE) [4] |
In Vitro | (-)-Huperzine A优先抑制四聚体AChE(G4形式)。在抑制AChE活性方面,(-)-Huperzine A比Tacrine,Physostigmine,Galanthamine,和Rivastigmine更有效,但是在抑制BuChE方面,(-)-Huperzine A效果却是最差的。(-)-Huperzine A 保护细胞免受过氧化氢,β-淀粉样蛋白,谷氨酸盐,缺血和Staurosporine 诱导的细胞毒性和细胞凋亡。这些保护作用与其减轻氧化应激,调节凋亡蛋白Bcl-2,Bax,P53,和caspase-3的表达,保护线粒体,上调神经生长因子及其受体,及干扰淀粉样前体蛋白代谢有关。[3] |
In Vivo | (-)-Huperzine A 处理动物模型和AD患者,可以改善学习和记忆障碍。(-)-Huperzine A有益功能包括:β-淀粉样蛋白肽加工的修饰,减少氧化应激,保护神经元防止细胞凋亡,调控神经生长因子(NGF)及NGF信号的表达和分泌。[2]大鼠杀害30分钟后,使用不同剂量水平的(-)-Huperzine A处理,对照组使用生理盐水,(-)-Huperzine A显著抑制皮质,海马区,纹状体,内侧隔核,延髓,小脑和丘脑中的乙酰胆碱酯酶活性。[3] |
Cell Experiment | (-)-Huperzine A(0.1-0.2 mg/kg; i.p.; daily; for 12 days)can alleviate the cognitive dysfunction and neuronal degeneration induced by i.c.v. infusion of beta-amyloid protein-(1-40)in rats[5]. |
