Synthesis and evaluation of a C-6 alkylated pyrimidine derivative for the in vivo imaging of HSV1-TK gene expression.

INTRODUCTION We report on the synthesis, radiolabeling, in vitro and in vivo characterization of N-Me-[(18)F]FHBT (6-(3-[(18)F]fluoro-2-(hydroxymethyl)propyl)-1,5-dimethylpyrimidin-2,4(1H,3H)-dione), a C-6-substituted N-1-methylated pyrimidine derivative as a reporter probe for imaging herpes simplex virus type 1 thymidine kinase (HSV1-TK) expression… (More)
