Outline of Final Research Achievements

Dozens of new trehalose-type autophagy inducers were discovered or synthesized. Among them, TRH-X was estimated as mass-producible and suitable as the material to synthesize further derivative compounds. Some of the TRH-X derivatives showed higher autophagy inducing activities than trehalose and other analogues. They would be the promising drug candidates for the treatment of neurodegenerative diseases to dissolve the aggregation of abnormal proteins in the neuronal cells.
The curative effect of trehalose in Alzheimer’s disease was evaluated using a model mouse. Trehalose administrated mice in the early stage of the disease showed significantly better recognitive function and reduced amyloid plaque. The development and application of the new trehalose analogue compound for the treatment of Alzheimer’s disease are expected.
