| Research Abstract |
[11C]PIB was synthesized and evaluated Quality control for Clinical use. By applying purification system,Radiochemical yield was 62.7% and radiochemical purity was 95% and more. On the other hand, EMSB (1-(2-mestyl-ethoxy)-2,5bis (phenylstyryl)benzene) is newly synthesized and (1-(125I-ethoxy)-2,5-bis (phenylstyryl) benzene) [125I]-EISB was obtained. The radiochemical yield and the radiochemical purity were 80-90% and 98.4% respectively. We injected [125I]-EISB to Alzheimer model mouse and analyzed its bio-distribution (%dose/g) of [125I]-EISB in the amyloid tissues. In the animal experiments showed that the bio-distribution (%dose/g) of [125I]-EISB gave a similar to the uptake as well as fluorescent agents MSB and PIB which have done in our institute. [125I]-EISB was a promising new radio-compound for the detection of the amyloid protein and make it possible to apply it to clinical use.
