| Outline of Final Research Achievements |
We found a natural resource derived component X, which increased Alzheimer Aβ42 protein in cellular level study. However, mice administrated X for long term were decreased Aβ42 in the brain and showed high level of learning and memory, compared to the control mice. Therefore, it was considered that X may promote the clearance mechanism of Aβ42 in the brain. In this study, we isolated and identified candidate compound Y from the component X with the cellular level study. We are preparing the mice administrated Y for long term. We are planning to Aβ42 production and ability of learning and memory in the Y administrated mice, to reveal the Aβ42 clearance mechanism of candidate compound Y.
