Synthesis and Characterization of a Novel 68Ga-Labeled P-bromobenzyl Lysine-Urea-ODAP PSMA Inhibitor

The authors synthesized seven ODAP-Urea-Lys derivatives characterized with p-bromobenzyl group conjugated to lysine. The ligands showed medium-to-high potency, with Ki values ranging from 27.9 nM to 0.94 nM.
