Abstract

Alzheimer’s disease is a typical neurodegenerative disorder, and its prevention or treatment poses great concern in advanced countries. In our survey of numerous natural resources with neurotrophic activities, we found that Anredera cordifolia improved memory impairment and increased cyclic adenosine monophosphate (AMP) response element-mediated transcription, an important step in signal transduction for memory formation. The extracts of this food were dissolved in methanol and then partitioned with three organic solvents and water, separating into n-hexane, ethyl acetate, n-butanol, and water layers. The n-butanol layer with the strongest activity on cyclic AMP-response element-dependent transcription was fractionated using silica gel column chromatography and then the activity was monitored using preparative high-performance liquid chromatography to give adenosine and cordysinin B, respectively. Both compounds showed a concentration-dependent increase in cyclic AMP-response element-mediated transcription activity. These results suggest that both adenosine and cordysinin B may participate in improving the action of A. cordifolia on memory impairment, and these actions, at least in part, result from the activation of adenosine A1, A2A, and A2B receptors.
