| Outline of Final Research Achievements |
For diagnosis and monitoring therapeutic efficacy of systemic amyloidosis diseases, we planned to develop a nuclear imaging probe with similar binding affinities to a variety of amyloid fibrils and fluorescent probes with a selective binding affinity to a specific amyloid fibril. Radioiodine labelled compound [125I]1 based on the structure of thioflavine T showed similar binding affinities to SAA fibril and Aβ fibril. In AA amyloid model mice, considerable accumulation of radioactivity was observed in predilection sites of AA amyloid such as the spleen, kidney, and liver. In addition, we synthesized fluorescent probes with a selective binding affinity to a specific amyloid fibril by investigating substituent groups.
