A concise one-pot synthesis of [18F]fluoromisonidazole from (2R)-(−)-glycidyl tosylate
摘要:
A rapid, one-pot synthesis of [F-18]fluoromisonidazole (1H-1-(3-[F-18]fluoro-2-hydroxypropyl)-2-nitroimidazole) (1) starting from [F-18]fluoride and (2R)-(-)-glycidyl tosylate (2) is described. The total time required for the synthesis, the radiochemical yield, and purity of the titled compound are ca. 80 min, 20%, and >98%, respectively.

Thus, (rac)‐, (R)‐, and (S)‐[18F]1 are effective radiolabelling reagents and can be used to develop PET radiotracers by examining

was suggested from a comparative study of in vitro radiosensitization in V79 cells that these lipophilic analogs may have reduction potentials close to those of fluoromisonidazole (FMISO) and misonidazole (MISO), known hypoxic cell radiosensitizers. The preparation of 18F-labeled FON (18FON) and FPN (18FPN) was achieved via two-steps through [18F]fluorideion displacement of tosylate precursors, in
