摘要： The present invention provides novel alpha-fluoroalkyl dihydrotetrabenazine compounds I wherein R1 is a C1-C10 fluorinated aliphatic radical; R2 is hydrogen or a C1-C10 aliphatic radical; R3 is hydrogen or a C1-C10 aliphatic radical; and R4 is a C1-C10 aliphatic radical, a C3-C10 cycloaliphatic radical, or a C3-C10 aromatic radical. The alpha-fluoroalkyl dihydrotetrabenazine compounds are provided in both racemic and enantiomerically enriched forms and may comprise either or both of fluorine-18 and fluorine 19. The alpha-fluoroalkyl dihydrotetrabenazine compounds are believed to possess high affinity for VMAT-2, a biomarker implicated in human diabetes. The alpha-fluoroalkyl dihydrotetrabenazine compounds comprising a fluorine-18 group are useful as PET imaging agents targeting the VMAT-2 biomarker. The non-radiolabled alpha-fluoroalkyl dihydrotetrabenazine compounds are useful as probes for the discovery of PET imaging agents.
