GBR-13119
GBR-13119 is a blood-brain barrier-permeable inhibitor of the presynaptic dopamine uptake system. GBR-13119 binds to dopamine uptake sites with high selectivity, without being affected by other neurotransmitter reuptake inhibitors. GBR-13119 exhibits a lipophilic systemic distribution profile with extremely low defluorination in rats, while it shows a differential characteristic of slow striatal washout in the brain of primates. GBR-13119 can serve as a PET tracer to achieve visualized imaging of the striatum in primates, and can reflect MPTP-induced dopaminergic neuron degeneration through reduced uptake. GBR-13119 can be widely applied to studies related to Parkinson's disease and dopaminergic neuron degeneration.

Biological Activity
[18F]GBR-13119 (7-10 μCi; i.v.; single dose) shows significantly reduced striatum/cerebellum ratios (≈50% reduction) in MPTP-lesioned C57BL/6 mice, indicating its ability to detect dopaminergic neuron degeneration[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
