Abstract:Objective To optimize the synthesis method of 18F-T807 and study preliminary biodistribution. Methods 18F-T807 was synthesized using an optimized method in TRACERlab FXFN synthesizer with a t-BOC(t-Butyloxy carbonyl)-protected 18F-T807 precursor NPPI-9 as starting material, improving experimental conditions for synthesis, then QC and biodistribution study in Wistar rats conducted. Results The improved synthesis conditions increased the synthesis yield from 20.5%±6.1% to 25.7%±5.8%. QC met the standard. Wistar rats had higher intake in kidney, liver, blood and lowest intake in brain, heart, lung. Conclusion The optimized synthesis method to synthesize 18F-T807 is simple and easy, and high yield, which can meet the needs of scientific research and clinical practice. |
