Abstract: The present invention relates to the novel benzofuran derivatives, the preparation thereof and the composition comprising the same. The benzofuran derivatives of the present invention showed potent inhibiting activity of beta-amyloid aggregation and cell cytotoxicity resulting in stimulating the proliferation of neuronal cells as well as recovering activity of memory learning injury caused by neuronal cell injury using transformed animal model with beta-amyloid precursor gene, therefore the compounds can be useful in treating or preventing cognitive function disorder.

Abstract: A composition comprising tanshinone compounds selected from the group consisting of miltirone, 1,2-didehydromiltirone, tanshinone IIA, tanshinone I and dihydrotanshinone I isolated from Salviae miltiorrhizae Bunge showing potent inhibiting effect on the aggregation and toxicity of beta-amyloid and recovering activity of memory learning disorder confirmed by Y maze study and Passive Avoidance study. Therefore it can be used as the therapeutics or health food for treating and preventing cognitive function disorder with safe.
