Outline of Final Research Achievements

Abnormality of the brain norepinephrine transporters (NET) has been reported in several psychiatric and neuronal disorders. NET is one of important targets for the diagnosis of these disorders. Therefore, we designed a new NET imaging probe for NET. A synthesized F-18 derivative had an affinity for NET and good Log P value for blood brain barrier permeability. This probe has a potential for NET imaging in the brain. Using mood disorder model rats, changes in NET probe accumulation were observed. Consequently, the accumulation of NET probe was significantly decreased in the locus coeruleus and the anteroventricular thalamic nucleus. About OXTR imaging probe, 4 novel F-18 derivatives were designed and synthesized.
