Research Abstract

Br-76 is an attractive positron emitter due to its long half-life (t1/2=16.1 h). In this study, Br-76-labeled amino acid derivatives were designed, and their potential as a tumor imaging agent was evaluated.
Among several Br-76-labeled amino acid derivatives, 2-[Br-76]bromo-alpha-methyl L-phenylalanine (2-[Br]-AMP) exhibited preferred pharmacokinetics and tumor accumulation in vivo. These findings suggest that 2-[Br-76]-AMP would constitute a potential new PET tracer for tumor imaging.
