Studies have confirmed that tumorigenesis is related to an imbalance of polyamine metabolism and over-expression of oncogenes resulting in the up-regulation of ornithine decarboxylase (ODC, the first rate-limiting enzyme for regulating intracellular polyamines biosynthesis), which has become a target for anti-tumor therapy. In this study, an ornithine derivative, N -(2-[ F]fluoropropionyl) ornithine (N -[ F]FPO), has been prepared and its potential utility for tumor PET imaging evaluated. N -[ F]FPO was successfully prepared via a
