  2-Fluoropyridine prosthetic compounds for the 18F labeling of bombesin analogues

  摘要：

  Acetylene-bearing 2-[F-18]fluoropyridines [F-18]FPy5yne and PEG-[F-18]FPyKYNE were prepared via efficient nucleophilic heteroaromatic [F-18]fluorination of their corresponding 2-trimethylammoniumpyrdinyl precursors. The prosthetic groups were conjugated to azide- and PEG(3)-modified bombesin(6-14) analogues via copper-catalyzed azide-alkyne cycloaddition couplings to yield mono- and di-mini-PEGylated ligands for PET imaging of the gastrin- releasing peptide receptor. The PEG(3)- and PEG(2)/PEG(3)-bearing F-18 peptides showed decreased lipophilicity relative to an analogous non-mini-PEGylated F-18 peptide. Assessment of water-soluble peptide pharmacokinetics and tumour-targeting capabilities in a mouse model of prostate cancer is currently underway. (c) 2013 Elsevier Ltd. All rights reserved.
