Regio-specific enzymatic glucosylation of triterpenoids from Antrodia camphorata and their biological activities

Abstract

The bacterial glycosyltransferase YjiC1 was used to glycosylate triterpenoids from the medicinal fungus Antrodia camphorata. Eleven new compounds were obtained from enzymatic reactions. Glucosylation could increase the inhibitory activities against COX-2, and improve the anti-inflammatory activities of Antrodia ergostanes on acute lung injury mice, especially (25R)-antcin C 7-O-β-D-glucoside.
