pharmacological action | dianthrone and anthrone glycoside components in Polygonum multiflorum Thunb can inhibit UGT1A1 enzyme activity, which is presumed to be the mechanism of hepatotoxicity. Analysis of the structure of 5 compounds found that the two anthracenone compounds: trans-emodin-emodin dianthrone and cis-emodin-emodin dianthrone can be biosynthesized by two molecules of emodin through enzyme catalyzed reaction. Previous research results show that the emodin-type anthraquinone compounds in Polygonum multiflorum can selectively inhibit UGT1A1 enzyme, and there is a structure-activity relationship. The 6-OH on the emodin-type anthraquinone parent nucleus is its pharmacophore, which affects the inhibition strength. |
