| | Florbenazine Usage And Synthesis |
| Description | Florbenazine (AV-133) is a fluorinated VMAT-2 ligand for PET. It is designed to measure dopaminergic degeneration by in vivo assessment of striat VMAT2 density in patients with Parkinson’s disease (PD). Besides differentiating PD from essential tremor and drug-induced parkinsonism, PET imaging of VMAT2 may help in differentiating Dementia with Lewy Bodies (DLB) from Alzheimer’s disease. AV-45 (florbetapir, AmyvidTM) is the first PET ligand to receive US FDA approval to assess neuritic plaque amyloid[1-2]. | | Uses | Florbenazine (AV-133) is a diagnostic imaging agent targeting the central nervous system monoamine transporter VMAT2, and its F-18 labeled form can be used for PET scanning. The biodistribution of [18F]Florbenazine in mice shows a high striatum/cerebellum ratio (0.48), which can be used for the diagnostic research of neurodegenerative diseases (including dementia with Lewy bodies and Parkinson's disease)[1]. | | References |
