Synthesis of 4-([18F]Fluoromethyl)phenyl Isothiocyanate and its Use in Labelling Oligonucleotides.
摘要:
4-([F-18] Fluoromethyl)phenyl isothiocyanate 8 was obtained from [F-18]fluoride and 4-(4-toluenesulfonyloxymethyl)phenyl isothiocyanate 5 in 13-15% isolated, decay-corrected radiochemical yield within 40 min from the end of cyclotron bombardment. The precursor 8 was used to label the oligonucleotide 5'-GCT,AAG,CGA,TGC,CTC, CGT-3', modified in the 5'-position with a hexylamine linker, in the 5'-position in up to 8% radiochemical yield.
