1-Benzyl-1,2,3,4-tetrahydroisoquinoline
1-benzyl-1,2,3,4-tetrahydroisoquinoline (1BnTIQ) as a possible PD-eliciting neurotoxin and evaluated its characteristics relevant to Parkinson disease (PD). 1BnTIQ exist in mammals and is proposed as possible PD-eliciting neurotoxin. PD is believed to be induced by the interaction of genetic predisposition and environmental factors, and a type of neurotoxin is proposed to be one of the environmental factors. 1BnTIQ inhibits [3H] dopamine uptake in HEK293 cells which stably express dopamine transporter. 1BnTIQ also inhibits NADH-ubiquinone oxidoreductase (complex I) in the mitochondrial respiratory chain. 1BnTIQ decreases the dopamine content in the mesencephalon in both dose- and time-dependent manners and it irreversibly reduced the dopamine content. Furthermore, it causes morphological changes in tyrosine hydroxylase-positive cells in the mesencephalon and reduced the number of cells.
