Natural R-(−)-xanthorrhizol possess a number of therapeutic activities including anti-cancer. The pharmacokinetic properties of that poorly aqueous soluble compound could be improved by incorporating it into polymeric materials. Glycerol can produce a functionalized polymer through a polycondensation process. Enzymatic polycondensation of glycerol and divinylesters was studied and xanthorrhizol was covalently loaded via a butanedioate linker to the polymer backbone. It was observed that xanthorrhizol loading to the polymer backbone increases with the increasing of the chain length of a dioate moiety. Enzyme-mediated xanthorrhizol release from a polymer backbone shows that the polymeric prodrug is able to release xanthorrhizol in a sustained manner. Therefore, the approach described here might be valuable for controlled loading and release of such phenolic sesquiterpenes from the polymeric prodrug.

► A number of poly (glycerol-co-dioate-co-butanedioate-xanthorrhizol) esters were synthesized and studied to address the pendant group loading ability.
► Novel pendant group loading method might be applicable for other biologically active natural phenolic compounds.
► Enzyme mediated release of xanthorrhizol from polymer backbone shows potential to use in DDS.
► Our results suggest that xanthorrhizol loading increases with increasing the chain length of dioate moiety.
