##STR00001##

Provided are a class of alkylphenol compounds and a preparation method therefor. Specifically provided are a new alkyl polyphenol compound as represented by chemical formula I, and a preparation method therefor and the use thereof in the treatment of metabolic syndrome.

##STR00001##

It discloses a compound of formula I that inhibits the activities of numerous of protein kinases involving the signaling of inflammatory cytokines, therefore, the compound can be used for treating cancers, autoimmune diseases and inflammatory diseases.

Provided are a cannabidiol derivative, a method for preparing same, and a composition for cognitive function improvement comprising same, in which cannabidiol derivative exhibits acetylcholinesterase inhibitory activity and butyrylcholinesterase inhibitory activity, as well as inhibitory activity against monoamine oxidase B, therefore it is possible to simultaneously treat a decrease in acetylcholine levels in brain tissue and a decrease in blood butyrylcholine levels, which are seen in patients with dementia, and to provide a more effective cognitive function improvement treatment by preventing brain cell damage.
