| Outline of Final Research Achievements |
The aim of this study was to explore the effects and underlying mechanisms of a newly synthesized scabronine G - methylester (SG-ME) on memory impairment in olfactory bulbectomized (OBX) mice, experimental animal models of depression and dementia. We observed that the memory impairment in OBX mice was improved at 24 hours after an intracerebroventricular (i.c.v.) injection of SG-ME. The present study has shown that SG-ME has anti-dementia effect, and the SG-ME activity to improve impaired memory is accompanied by enhancement of hippocampal cell proliferation mediated via activation of brain-derived neurotrophic factor - extracellular signal-regulated kinase - cAMP-response element binding protein (BDNF-ERK-CREB) signal pathway on neuronal cells. These results indicate that SG-ME may become a potential leading compound for drug development for Alzheimer's disease.
