摘要
目的分析正电子药物合成器合成基氟-18标记的四乙酰脱氧葡糖[1,3,4,6-四乙酰基-O-2-^(18)F-2-脱氧-β-D葡萄糖,简称^(18)F-FDG-(OAc)_(4)]的稳定性和实用性。方法基于合成器及其合成工艺流程,进行^(18)F-FDG-(OAc)4合成产量和质量控制及其与氟-18标记的脱氧葡萄糖(2-[18F]-氟-2-脱氧-D-葡萄糖,简称18F-FDG)在小鼠体内的生物分布异同分析。结果连续3批合成^(18)F-FDG-(OAc)4的成功率为100%,产率分别为59.64%、60.61%、59.72%,产品溶液为无色透明溶液,放射性化学纯度≥96%(Rf值为0.8~0.9),放射性核纯度为100%。^(18)F-FDG-(OAc)_(4)与18F-FDG注入小鼠,后各个脏器的放射性摄取均无差别,差异无统计学意义(P>0.05)。结论正电子药物合成器合成^(18)F-FDG-(OAc)4的流程简单、便捷,合成成功率和合成产率较高,具有较强的稳定性和实用性。
Objective To analyze the stability and practicality of the positron emission tomography drug synthesizer for the synthesis of ^(18)F-FDG-(OAc)4.Methods Based on the synthesizer and its synthetic process,the synthesis yield and quality control of ^(18)F-FDG-(OAc)_(4) were carried out,and the similarities and differences in biological distribution in mice between ^(18)F-FDG-(OAc)_(4) and ^(18)F-FDG were analyzed.Results The success rate of ^(18)F-FDG-(OAc)_(4) in 3 consecutive batches was 100%,and the yields were 59.64%,60.61%,and 59.72%,respectively.The product solution was colorless and transparent,with radioactive chemical purity was≥96%(Rf value was 0.8-0.9)and radioactive nuclear purity was 100%.There were no significant differences in the radioactive uptake of various organs after injecting ^(18)F-FDG-(OAc)_(4) and 18F-FDG into mice(P>0.05).Conclusion The synthesizer provides a simple and convenient process for the synthesis of ^(18)F-FDG-(OAc)_(4) with high synthesis success rate and yield,showing strong stability and practicality.
