Novel 18F-Labeled 1-Hydroxyanthraquinone Derivatives for Necrotic Myocardium Imaging.


ABSTRACT: Rapid detection and precise evaluation of myocardial viability is necessary to aid in clinical decision making whether to recommend revascularization for patients with myocardial infarction (MI). Three novel 18F-labeled 1-hydroxyanthraquinone derivatives were synthesized, characterized, and evaluated as potential necrosis avid imaging agents for assessment of myocardial viability. Among these tracers, [18F]FA3OP emerged as the most promising compound with best stability and highest targetability. Clear PET images of [18F]FA3OP were obtained in rat model of myocardial infarction and reperfusion at 1 h after injection. In addition, the possible mechanisms of [18F]FA3OP for necrotic myocardium were discussed. The results showed [19F]FA3OP may bind DNA to achieve targetability to necrotic myocardium by intercalation. In summary, [18F]FA3OP was a more promising "hot spot imaging" tracer for rapid visualization of necrotic myocardium.
