Abstract

Sulfur-[F]fluoride exchange radiochemistry is a rapid and convenient method for incorporating fluorine-18 into biologically active molecules. We report a fully automated radiolabelling procedure for the synthesis of a [F]SOF-bearing prostate specific membrane antigen (PSMA) targeted ligand ([F]5) using the GE FASTLab™ cassette-based platform in a 25.0 ± 2.6% radiochemical yield (decay corrected). Uptake and correlated with PSMA expression, and the radioligand exhibited favourable biodistribution and pharmacokinetic profiles.

摘要

硫-[F]氟交换放射化学是一种将氟-18引入生物活性分子的快速便捷方法。我们报告了一种全自动放射性标记程序,用于使用GE FASTLab™基于盒式平台合成带有[F]SOF的前列腺特异性膜抗原(PSMA)靶向配体([F]5),放射化学产率为25.0±2.6%(衰变校正)。摄取与PSMA表达相关,并且该放射性配体表现出良好的生物分布和药代动力学特征。
