Sweetening pharmaceutical radiochemistry by18f-fluoroglycosylation: Recent progress and future prospects

Abstract

In the field of18F-chemistry for the development of radiopharmaceuticals for positron emission tomography (PET), various labeling strategies by the use of prosthetic groups have been implemented, including chemoselective18F-labeling of biomolecules. Among those, chemoselective18F-fluoroglycosylation methods focus on the sweetening of pharmaceutical radiochemistry by offering a highly valuable tool for the synthesis of18F-glycoconjugates with suitable in vivo properties for PET imaging studies. A previous review covered the various18F-fluoroglycosylation methods that were developed and applied as of 2014 (Maschauer and Prante, BioMed. Res. Int. 2014, 214748). This paper is an updated review, providing the recent progress in18F-fluoroglycosylation reactions and the preclinical application of18F-glycoconjugates, including small molecules, peptides, and high-molecular-weight proteins.
