ABSTRACT
Objective To explore a new 18F multifunctional synthesis module with two vessels to synthesize various kinds of 18F labeled radiopharmaceuticals for clinical utilities. Methods The module with two vessels contained five systems, capture of F ion, the first reaction vessel, the second reaction vessel, high performance liquid chromatography (HPLC) purification, and solid extraction. The two vessels were made of transparent glass and were used to prepare complex products by nucleophilic reaction or hydrolyzation. Results The complex compounds of 18F-ethyl-choline, 18F-N-succinimidyl-4-18 F-fluorobenzoate (SFB), and common compounds of 18F-fluorodeoxyglucose (FDG), 18F-3'-deoxy-3'-18 F-fluorothymidine (FLT) were synthesized by the new module. The uncorrected synthesis yield (EOS) of 18F-SFB, 18F-ethylcholine, and 18F-FDG were (28.2±1.9)% (n=5), (22.5±3.8)%(n=6), and (58.2±5.4)% (n=32), respectively. The corrected synthesis yield of 18F-FLT was (30.1 ±6.2)% ( n = 10). In addition,11C-N-methyl-N-( 1-methylpropyl )-1-( 2-corophenyl )-isoquinoline-3 -carboxamide ( PK11195 ) was also prepared by the module with the yield of (31.2 ± 2.5) % ( n = 3 ). Conclusions The new module with two vessels has been used for synthesis of many 18F compounds and it may have the potential to be used for other more 18F radiopharmaceuticals.
