FLORTAUCIPIR is a gamma-carboline derivative. Its 18F radiolabelled form is a highly selective positron emission tomography (PET) tracer targeting paired helical filament (PHF)-tau in the brain. This tracer is studying for clinical assessment in patients with various tauopathies, including Alzheimer's disease.
