Synthesis of three novel 2'-deoxy-2'-[F-18]fluoro-1-beta-D-arabinofuranosyluracil derivatives [F-18] FPAU, [F-18]-FBrVAU, and [F-18] FTMAU is reported. The compounds were synthesized by coupling of 1-bromo-2-deoxy-2- fluoro sugars with corresponding silylated uracil derivatives. In vitro cell uptake indicated that all three compounds are taken up selectively in RG2TK+ cells with negligible uptake in RG2 cells. The results indicate that [F-18]FBrVAU and [F-18]FTMAU have better uptake profiles in comparison to [F-18]FPAU and have potential as PET probes for imaging HSV1-tk gene expression.
