Abstract

In this study, three 18F-labeled crown ether fused anilinoquinazoline derivatives ([18F]11a–c) were synthesized and evaluated as potential tumor imaging probes. The biodistribution results of [18F]11b were good. Compared with [18F]-fludeoxyglucose and l-[18F]-fluoroethyltyrosine in the same animal model, [18F]11b had better tumor/brain, tumor/muscle, and tumor/blood uptake ratios. Overall, these results suggest that [18F]11b is promising as a tumor imaging agent for positron emission tomography.
