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 F-labeled 1-hydroxyanthraquinone derivatives were synthesized, characterized, and evaluated as potential necrosis avid imaging agents for assessment of myocardial viability. Among these tracers, [F]FA3OP emerged as the most promising compound with best stability and highest targetability. Clear PET images of [F]FA3OP were obtained in rat model of myocardial infarction and reperfusion at 1 h after injection. In addition, the possible mechanisms of [F]FA3OP for necrotic myocardium were discussed. The results showed [F]FA3OP may bind DNA to achieve targetability to necrotic myocardium by intercalation. In summary, [F]FA3OP was a more promising "hot spot imaging" tracer for rapid visualization of necrotic myocardium.
快速检测和精确评估心肌活力对于辅助临床决策是否为心肌梗死（MI）患者推荐血运重建至关重要。合成了三种新型F标记的1-羟基蒽醌衍生物，对其进行了表征，并评估其作为评估心肌活力的潜在坏死亲和成像剂。在这些示踪剂中，[F]FA3OP成为最有前景的化合物，具有最佳的稳定性和最高的靶向性。在注射后1小时，在心肌梗死和再灌注大鼠模型中获得了清晰的[F]FA3OP PET图像。此外，还讨论了[F]FA3OP对坏死心肌的可能作用机制。结果表明，[F]FA3OP可能通过嵌入结合DNA以实现对坏死心肌的靶向性。总之，[F]FA3OP是一种更有前景的“热点成像”示踪剂，可快速显示坏死心肌。
