Outline of Final Research Achievements

In this study, we designed and synthesized a 68Ga labeled PET probe (68Ga-Df9-Ex(9-39)) targeting GLP-1 receptor for early diagnosis and preemptive medicine of diabetes. 67Ga-Df9-Ex(9-39) was synthesized with high specific radioactivity and radiochemical yield. In addition, it showed the high uptake in normal mouse pancreas and the radioactivity was maintained until 120 min after injection. These results suggested that 68Ga-Df9-Ex(9-39) may be a useful probe for imaging GLP-1 receptors.
