Outline of Final Research Achievements

In this study, we evaluated 18F-labeled phosphonium derivatives as a tumor imaging agent. We synthesized various phosphonium derivatives and performed biological evaluation. Among them, 18F-TAP-D was selected as a candidate for a tumor imaging agent. In the cellular uptake study, good uptake of 18F-TAP-D was observed in tumor cells. However, we could not confirm the specific radioactivity accumulation to the tumor in the PET study with tumor-bearing mice.
