摘要

采用"一锅法"和TRACERlab FXF-N自动化合成装置

以3-N-t-叔丁氧羰基-1-[5’-O-（4

4’-二甲氧基三苯甲基）-2’-脱氧-3’-O-（4-硝基苯磺酰基）-β-D-苏型阿呋喃糖基]胸腺嘧啶为前体

在同一反应瓶中经亲核氟化、盐酸水解两步反应及HPLC分离纯化制备18F-FLT注射液。以乙二醇二对甲苯磺酸酯为起始原料

在同一反应瓶中经亲核氟化和烷基化两步反应及HPLC分离纯化得18F-FET注射液。18F-FLT和18F-FET总合成时间分别约为60min和50min

未校正的放化产率均大于20%

放化纯度均大于95%。18F-FLT和18F-FET注射液质量控制指标符合放射性药物质量要求。

Abstract

For early diagnosis for malignant tumors with the different metabolic imaging agents

a fully automated synthetic technology of 3’-deoxy-3’-[18F]fluorothymidine (18F-FLT) and O-(2-18F-fluoroethyl)-L-tyrosine (18F-FET) was studied in this paper. Automated synthesis of 18F-FLT and 18F-FET was performed by one-pot two-step reaction procedure at TRACERlab FXF-N system. 18F-FLT injection was obtained via two-step reaction including nucleophilic fluorination of 3-N-t-butoxycarbonyl-1-[5’-O-(4

4’-di-methoxytriphenylmethyl)-2’-deoxy-3’-O-(4-nitrobenzenesulfonyl)- β-D-threopentofuranosyl]thymine

the precursor molecule

with 18F-fluoride and subsequent hydrolysis of the pro- tecting group with 1 mol/L HCl at the same reaction vessel

and purification with HPLC system. 18F-FET injection was also prepared via two-step reaction including nucleophilic fluorination of 1

2-di(4-methylphenylsulfonyloxy)ethane as the starting material and following by alkylation of L-tyrosine at the same reaction vessel

and purification with HPLC system. Fully automated synthesis of 18F-FLT and 18F-FET was completed within the total synthesis time of about 50 and 60 min

respectively. The uncorrected radiochemical yields of 18F-FLT and 18F-FET were above 20% and radiochemical purities were more than 95%. The quality control indexes of 18F-FLT and 18F-FET injection meet the requirements of radiopharmaceuticals quality.
