摘要: [18F]AV1451 is a commonly used radiotracer for imaging tau deposits in Alzheimer’s disease (AD) and related non-AD tauopathies. Existing radiosyntheses of require complex purifications to provide doses suitable use clinical studies. To address this issue, we have modified the synthesis only 0.5 mg precursor, optimized Boc-deprotection step developed simplified method HPLC purification radiotracer. An using TRACERLab FXFN module led high radiochemical yield (202 ± 57 mCi per synthesis) with excellent purity (98 ± 1%) good specific activity (2521 ± 623 Ci/mmol). updated operationally simple has been that fully automated prepares PET
