Abstract:
The present invention relates to dicaffeoyl spermidine cyclized derivatives and a preparation method and use thereof. Biological activity experiments show that the dicaffeoyl spermidine cyclized derivatives of the present invention have anti-Senile dementia activity and antioxidant activity, and their activity are even better than that of a positive control drug, thus suitable for the prevention and treatment of neurodegenerative diseases such as Senile dementia.

Claim (Index 3):
The dicaffeoyl spermidine cyclized derivatives or the pharmaceutically acceptable salts thereof according to  claim 2 , wherein the inorganic acid is hydrochloric acid, hydrobromic acid, sulfuric acid, or nitric acid, and the organic acid is trifluoroacetic acid, acetic acid, propionic acid, malonic acid, butyric acid, lactic acid, methanesulfonic acid, ethanesulfonic acid, benzenesulfonic acid, p-toluenesulfonic acid, maleic acid, benzoic acid, succinic acid, picric acid, tartaric acid, citric acid, or fumaric acid.
