[18F]LSN3316612 is a PET radiotracer for quantifying levels of O-GlcNAc hydrolase (OGA) in the brain. OGA is an enzyme involved in the post-translational modification of tau protein, and OGA may be a useful biomarker for neurodegenerative disease drug development. The fluorine radiolabel was introduced through nucleophilic aromatic substitution onto a nitropyridine.
