metabolizer (FAME) software, electrochemical oxidations, in vitro studies with rat liver microsomes, and in vivo metabolism studies after application of the PET tracers [18F]1–4 to mice were performed. Combined liquid chromatography and mass spectrometry (HPLC–MS) analysis allowed structural identification of non‐radioactive metabolites. Radio‐HPLC and radio‐TLC provided information about the presence
σ的成像1种受体在脑中由氟化的放射性示踪剂将用于σ的验证1个受体的药物靶标,以及用于在中枢神经系统疾病的鉴别诊断。4个同源的生物转化氟化PET示踪剂1'-苄基-3-(ω-氟到ω氟丁基)-3 ħ -螺[2]苯并呋喃-1,4'-哌啶]([ 18 F] 1 - 4)被调查了。在使用快速代谢(FAME)软件,电化学氧化,在体外研究用大鼠肝微粒体硅的研究,在体内代谢研究的PET示踪剂的应用后[ 18 F] 1 - 4对小鼠进行。液相色谱和质谱联用(HPLC–MS)分析可以对非放射性代谢物进行结构鉴定。放射性HPLC和radio-TLC提供了有关未改变的母体放射性示踪剂及其放射性代谢物的信息。Radiometabolites均未的[应用后脑中发现18 F] 2 - 4,但肝脏,血浆和尿样品含有几个radiometabolites。少于2%的[ 18 F] 4注射剂量到达大脑,使得[ 18 F] 4较[
