| Outline of Final Research Achievements |
It is said that the effect to Alzheimer or dementia of the ginkgo biloba is caused by ginkgolides, but an evaluation halves that because of the low lipophilicity of ginkgolides, the dramatic curative effect were not observed in the most of cases. In order to overcome these problems, we planned the synthesis of glicosylated which might promote the uptake of ginkgolides to the brain through glucose transporter. In addition, we planned that the in vivo dynamics of the ginkgolide derivatives which we designed composed a short-life radionuclide-labeled derivative and evaluated it.
