Sulfur heteroatom substitution at the C4 position of 18F-labeled fatty acids yields a tracer that is retained in proportion to the beta-oxidation rates in mammalian tissue, particularly hypoxic myocardium. Most preferably, the invention is embodied in an [18F]fluoro-4-thia-fatty acid having a chain length of between 8 to 20 carbon atoms. The 18F-labeled 4-thia fatty acids of this invention find particular utility the radiolabelling of tissue sites (e.g., myocardium) for purposes of positron emission tomography.
硫杂原子取代在18F标记的脂肪酸的C4位置产生一种示踪剂,在哺乳动物组织中与β氧化速率成比例保留,尤其是在缺氧的心肌中。最好的情况下,该发明体现在一种链长在8至20个碳原子之间的[18F]氟-4-硫脂肪酸中。本发明的18F标记的4-硫脂肪酸在组织位点(如心肌)的放射标记方面具有特殊的用途,用于正电子发射断层扫描。
