Abstract

The invention discloses vitamin A compound and paeonol condensed derivatives and a preparation method. The vitamin A compound and paeonol condensed derivatives include derivatives in structures I-VII shown as follows; a structure I is ester formed by paeonol and all-trans retinoic acid; a structure II is ester formed by paeonol and 13-cis-retinoic acid; a structure III is ester formed by paeonol and acitretin; a structure IV is ester formed by paeonol and 9-cis-retinoic acid; a structure V is ester formed by paeonol and adapalene; a structure VI is ester formed by paeonol and tazarotene; a structure VII is ester formed by paeonol and bexarotene. By the vitamin A compound and paeonol condensed derivatives and the preparation method, irritation of vitamin A compounds to skin mucosa is relieved; after application to skin, the vitamin A compounds and paeonol are released under the action of hydrolase to dissolve cutin, promote epithelial cell differentiation and the like so as to realize anti-inflammatory and anti-oxidation functions.

Description

Technical field [0001] The invention relates to the field of physiologically active substances, in particular to a derivative of a vitamin A compound condensed with paeonol and a preparation method. Background technique [0002] Vitamin A is involved in the biosynthesis of rhodopsin, embryo formation, cell growth and differentiation. Retinol and retinol fatty acid esters are converted into each other in the body, and retinol fatty acid esters are the main storage form. Retinol is oxidized to retinal, which continues to be oxidized to retinoic acid. Retinoic acid is considered to be the active form of vitamin A, which binds to nuclear receptors and regulates gene expression. The natural vitamin A compounds currently used are mainly retinol, retinol fatty acid esters, retinal, retinoic acid, retinoic acid derivatives, retinoic acid isomers (aliretinoic acid, isovitamin A acid). These compounds belong to the first generation of vitamin A substances. The representative of the se...
