Changes in the magnitude of the mitochondrial membrane potential occur in a range of important pathologies. To assess changes in membrane potential in patients, we set out to develop an improved mitochondria-targeted positron emission tomography probe comprising a lipophilic triphenylphosphonium cation attached to a fluorine-18 radionuclide via an 11-carbon alkyl chain, which is well-established to
线粒体膜电位大小的变化发生在一系列重要的病理中。为了评估患者膜电位的变化,我们着手开发一种改进的线粒体靶向正电子发射断层扫描探针,该探针包含通过 11-碳烷基链与氟 18 放射性核素连接的亲脂性三苯基鏻阳离子,该探针已被证实可有效地运输到线粒体并定位于线粒体内。在这里,我们描述了该探针 11-[(18) F] 氟十一烷基-三苯基鏻 (MitoF) 的放射合成,它来自未添加载体的 [(18) F] 氟化物,以及在良好放射化学中制备它的全自动合成方案产率(合成结束时为 2-3 GBq)和放射化学纯度(97-99%)。
