Fig. 3From: A convenient and efficient total solid-phase synthesis of DOTA-functionalized tumor-targeting peptides for PET imaging of cancerStructures of the bombesin peptide derivatives prepared by solid-phase peptide synthesis. DOTA was attached to the peptide from cyclen precursor or commercial DOTA-tris-t-Bu ester.
