Norepinephrine (NE), acting as both a neurotransmitter and hormone, plays a significant role in regulating the action of the brain and body. Many studies have demonstrated a strong correlation between mental disorders and aberrant NE levels. Therefore, it is of urgent demand to develop in vivo analytical methods of NE for diagnostic assessment and mechanistic investigations of mental diseases. Herein, we report a F MRI probe (NRFP) for sensing and imaging NE, which is constructed by conjugating a gadolinium chelate to a fluorine-containing moiety through a NE-responsive aromatic thiocarbonate linkage. The capacity and specificity of NRFP for detecting NE is validated with in vitro detecting/imaging experiments. Furthermore, the feasibility of NRFP for visualizing NE in animals is illustrated by ex vivo and in vivo imaging experiments, demonstrating the promising potential of NRFP for selective detection and specific imaging of NE in deep tissues of living subjects.
去甲肾上腺素(NE)既是一种神经递质,也是一种激素,在调节大脑和身体的功能方面发挥着重要作用。许多研究表明,精神障碍与 NE 水平异常之间存在很强的相关性。因此,迫切需要开发用于诊断评估和精神疾病机制研究的 NE 的体内分析方法。在此,我们报告了一种用于检测和成像 NE 的 F MRI 探针(NRFP),它是通过将镧系元素螯合物与含氟部分通过 NE 响应性芳基硫代碳酸盐键连接而构建的。通过体外检测/成像实验验证了 NRFP 检测 NE 的能力和特异性。此外,通过离体和在体成像实验说明了 NRFP 用于可视化动物体内 NE 的可行性,表明 NRFP 具有在活体深部组织中选择性检测和特异性成像 NE 的巨大潜力。
