In 2017, the FDA authorized 5-aminolevulinic acid (5-ALA) for intraoperative optical imaging of suspected high-grade gliomas. This was the first authorized optical imaging agent for brain tumor surgery to enhance the visualization of malignant tissue. Herein we report the synthesis of a racemic and enantiopure fluorinated analog of 5-ALA, i.e., 3-fluoro-5-aminolevulinic acid (3F-5-ALA). We anticipate that these studies will provide the foundation for the future construction of a fluorine-18-labeled 5-ALA PET tracer to be used for functional and metabolic imaging of gliomas.
2017 年，FDA 批准了 5-氨基酮戊酸（5-ALA）用于疑似高级别胶质瘤的术中光学成像。这是第一个被授权用于脑肿瘤手术的光学成像剂，用于增强恶性组织的可视化。在此，我们报告了 5-ALA 的外消旋和对映纯氟代类似物，即 3-氟-5-氨基酮戊酸（3F-5-ALA）的合成。我们预计这些研究将为未来构建用于胶质瘤功能和代谢成像的氟-18 标记的 5-ALA PET 示踪剂奠定基础。
