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 1):
Dicaffeoyl spermidine cyclized derivatives with the following structure formula, or pharmaceutically acceptable salts thereof, wherein, R 1 , R 2 , and R 3  are hydroxy, methoxy, or optionally substituted glycosyl, R 4  and R 5  are both \u2014CH\u2550 or \u2014CH 2 \u2014, R 6  and R 7  are both \u2014CH\u2550 or \u2014CH 2 \u2014, wherein the optionally substituted glycosyl is optionally substituted with one or more of the following monosaccharide groups and disaccharide groups or polysaccharide groups formed by the following monosaccharides selected from the group consisting of: glucosyl, glucuronyl, mannosyl, galactosyl, allosyl, fructosyl, sorbosyl, furanosyl, rhamnosyl, quinovosyl, arabinosyl, lyxosyl, xylosyl, ribosyl.
