Synthesis and Radiosynthesis of Prospective 2-Nitroimidazole Hypoxia­ PET Tracers via Thiazolidine Ligation with 5-Fluorodeoxyribose (FDR)

open access: yesSynOpen, 2017
The first prospective fluorinated PET tracers for imaging hypoxia obtained via thiazolidine-ligation are reported. Three 1,2-thiol-amine linkers were combined with four different 2-nitroimidazole spacers via amide or urea bond formation.
