| 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]. |
