A simple, continuous-flow solid-phase radiosynthesis method has been developed for the generation of [18F]triflyl fluoride as a source of [18F]fluoride for the preparation of 18F labeled radiopharmaceuticals without the ne

Imaging of poly (ADP-ribose) polymerase-1 (PARP-1) expression in vivo is a potentially powerful tool for developing PARP-1 inhibitors for drug discovery and patient care. We have synthesized several derivatives of benzimidazole carboxamide as PARP-1 inhibitors, which can be 18F-labeled easily for positron emission tomographic (PET) imaging. Of the compounds synthesized, 12 had the highest inhibition potency for PARP-1 (IC50 = 6.3 nM). [ 18F]12 was synthesized under conventional conditions in high specific activity with 40-50% decay-corrected yield. MicroPET studies using [ 18F]12 in MDA-MB-436 tumor-bearing mice demonstrated accumulation of [18F]12 in the tumor that was blocked by olaparib, suggesting that the uptake of [18F]12 in the tumor is specific to PARP-1 expression.
