摘要
内源性神经毒素1-甲基-6,7-二羟基-1,2,3,4-四氢异喹啉(salsolinol,Sals)为多巴胺代谢产物,通过诱导氧化应激损伤和凋亡参与帕金森病(Parkinson's disease,PD)的发病机制。1-甲基-6,7-二羟基-1,2,3,4-四氢异喹啉是致使多巴胺能神经元选择性死亡的理想神经毒素,其可模拟帕金森病缓慢发展的自然疾病进程,可使大脑能够慢慢适应进行性损伤。通过诱导氧化应激损伤,诱导凋亡的发生,使其近年来成为研究帕金森病的重要工具药物。
Endogenous neurotoxin 1-methyl-6,7-dihydroxy-1,2,3,4-tetrahydroisoquinoline( salsolinol,Sals),an endogenous dopamine metabolite,were shown to be toxic to dopaminergic neurons in vitro as well as in vivo,and was known to be involved in the pathogenesis of Parkinson' s disease( PD). Sals is a more realistic model for selective toxicity to nigral dopaminergic neurons,and mimic the natural course of PD that develops slowly,allowing the brain to adapt to progressive damage. Sals lead to neurotoxicity in dopaminergic cells through induction of oxidative stress and apoptotic dopaminergic cell death,which made it as an important tool drugs to study the pathogenesis of PD.
