CFN-MPS-200模块自动化制备18F-FLT及其质量控制与生物评价
Quality Control and Biological Assessment of Automated Synthesized 3'-deoxy-3'-18F-fluorothymidine using CFN-MPS-200 Module
摘要
Abstract
Objective To synthesize 3'-deoxy-3'-18F-fluorotyhymidine (18F-FLT) using CFN-MPS-200 automatic synthesis module,and evaluate its distribution in Wistar rats.Methods We used 3-N-Boc-5'-O-dimethoxytrityl-3'-O-nosyl-thymidine (Boc-FLT)-percursor as raw material to synthesize 18F-FLT without residual solvents.Its radiochemical purity was confirmed with radio-HPLC and thin layer chromatography (TLC).Normal Wistar rats were injected with 18F-FLT and underwent PET scanning.Results The entire preparation procedure took about 60 min,which resulted in a radio chemical yield of (24 ± 5) % (after attenuation correction,n =20) and radiochemical purity of over 99%,with 1.11 × 109 Bq/mL specific activity.The 18F-FLT solution was colorless and had a pH value between 7.0-8.0.18F-FLT was mainly concentrated in the kidney,bladder,liver,bone marrow and Liver of normal Wistar rats.Conclusion Automated synthesis of 18F-FLT using CFN-MPS-200 is a stable method,with high yield,safety without solvent,and acceptable quality.关键词
