摘要: A dopamine-derived 1(R),2(N)-dimethyl-6,7-dihydroxy-1,2,3,4-tetrahydrosioquinoline [N-methyl-(R)salsolinol] was found to occur enantio-selectively in human brain. This isoquinoline induced parkinsonism rat after injection the striatum, and behavioral, biochemical pathological changes were very similar those Parkinson’s disease. N-Methyl-(R)salsolinol depleted dopamine neurons substantia nigra without necrotic tissue reaction, which may be due apoptotic death process, as proved by its induction of DNA damage dopaminergic neuroblastoma SH-SY5Y cells. increase significantly cerebrospinal fluid parkinsonian patients. All these results suggest that N-methyl-(R)salsolinol an endogenous neurotoxin cause disease enzymes involved biosynthesis catabolism factors pathogenesis this
