Translating the concept of peptide labeling with 5-deoxy-5-[18F]fluororibose into preclinical practice: 18F-labeling of Siglec-9 peptide for PET imaging of inflammation.

Peptide glycosylation with 5-deoxy-5-[(18)F]fluororibose was translated into preclinical settings. The novel (18)F-labeled Siglec-9 peptide was produced using an automated synthesis procedure. The (18)F-labeled Siglec-9 peptide showed favorable binding in the animal model of inflammation in vivo.
