正电子(β+)发射断层扫描(PE)是一种强大的,非侵入性的工具,用于在体内,三维成像的生理结构和生化途径。PET成像的持续增长依赖于放射性药物(用短寿命放射性核素标记的生物活性分子,如氟-18)的相应增加。这种独特的需要,以纳入短寿命的氟-18原子(t1/2 = 109.77分钟),尽可能晚的合成途径,使方法的发展,使快速和有效的后期阶段的研究领域内的权利。在这篇综述中,我们描述的战略与氟-18,包括经典的氟-18放射化学和新兴技术的后期反应,以及标记技术,如微流体和固相放射化学的放射性标记。氟-18标记的放射性药物的效用通过PET成像在医疗保健、个性化医疗和药物发现环境中的最新应用而展示。
Positron (β+) emission tomography (PE) is a powerful, noninvasive tool for the in vivo, three-dimensional imaging of physiological structures and biochemical pathways. The continued growth of PET imaging relies on a corresponding increase in access to radiopharmaceuticals (biologically active molecules labeled with short-lived radionuclides such as fluorine-18). This unique need to incorporate the short-lived fluorine-18 atom (t1/2 = 109.77 min) as late in the synthetic pathway as possible has made development of methodologies that enable rapid and efficient late stage fluorination an area of research within its own right. In this review we describe strategies for radiolabeling with fluorine-18, including classical fluorine-18 radiochemistry and emerging techniques for late stage fluorination reactions, as well as labeling technologies such as microfluidics and solid-phase radiochemistry. The utility of fluorine-18 labeled radiopharmaceuticals is showcased through recent applications of PET imaging in the healthcare, personalized medicine and drug discovery settings.
