Аннотация

[18F]Fluoroaliphatic carboxylic acids are important PET tracers that have demonstrated a considerable potential to address the fatty acid oxidation-dependent processes in clinical patients. Herein, we report an efficient radiosynthetic approach to ω-[18F]fluoroaliphatic carboxylic esters and acids by nucleophilic radiofluorination of the readily available iodocarboxylic esters. Methyl 6-[18F]fluorohexanoate was further applied as a starting material for the preparation of the succinimide ester (NHS ester)-containing bifunctional radiofluorinated prosthetic group in two simple steps, 10 min each. The synthesized NHS ester of 6-[18F]fluorohexanoic acid can serve as an important reagent for a quick and efficient conjugation with peptides or proteins via amino groups of lysines.
