| 内容記述 | N-[18F]Fluoroethyl-4-piperidyl acetate([18F]FEtP4A),an analog of [11C]MP4A for mapping brain acetylcholineseterase(AchE)activity,was prepared by reacting 4-piperidyl acetate(P4A)with [18F]fluoroethyl bromide([18F]FEtBr) using a newly developed automated system.Preliminary evaluation showed that the initial uptake of [18F]FEtP4A in the mouse brain was>8% injected dose/g tissue.The distribution pattern of[18F]FEtP4A in the brain was striatum >cerebral cortex>cerebellum within 10-120 min post-injection,which reflected the distribution rank pattern of AchE activity in the brain. Moreover,chemical analysis of in vivo radioactive metabolites in the mouse brain indicated that 83% of [18F]FEtP4A was hydrolyzed to N-[18F]fluoroethy1-4-piperidinol([18F]FEtP4OH)after 1 min intravenous injection. From these results,[18F]FEtP4A may become a promising PET tracer for mapping the AchE in vivo. | |||||
