Outline of Final Research Achievements |
This study is aimed to investigate the relationship between tropical area-specific endemic neurodegenerative diseases and their dietary habits. We performed a field survey about the distribution of Annona Muricata, the occurrence of the disease, and their dietary habits, especially in Guam. We clarified that O,O-dimethylcoclaurine (DMC) involved in the Annona Muricata inhibits P-glycoprotein (P-gp) and is also a substrate of P-gp. DMC exerted weak neurotoxicty in in vivo. Taken together, it is suggested that DMC might be one of the candidate substances related to the disease.
