| Outline of Final Research Achievements |
we made a precursor EMSB and 19F-EFSB labeled stable isotope fluorine on EMSB to develop a new imaging probe18F-EFSB that detects systemic amyloidosis by PET examination. As a result of histochemical analysis, 19F-EFSB specifically accumulated in all disease type amyloid. 18F-EFSB was efficiently labeled with a radiochemical purity of 81.7 ± 5.1%(n=3) by reaction at 200 degree. for 5 minutes.
We also determined the optimal synthesis time and clarify stability of 125I-EISB in saline and human serum, respectively. As a result,high radioactive purity 95.88±3.19% was obtained in 10 minutes by our synthesis and the radiochemical purity was97.83±1.40% (n=6) applying our purification system.
