Abstract
Eugenol the essential component over 90 of clove oil from Eugenia caryophyllata Thunb Myrtaceae is a phenolic compound well known for its versatile pharmacological actions including analgesic local anesthetic antiinflammatory antimicrobial antitumor and hairgrowing effects However the application of eugenol is greatly limited mainly because of its unwanted physicochemical properties such as low solubility liability to sublimation and pungent odor Since glycosylation has been suggested to improve the physicochemical and biological properties of the parental compound we have previously developed a novel and efficient way to biosynthesize highly purified eugenol αDglucopyranoside αEG In light of the widely acknowledged importance of pure eugenol and the potential superiority of the glycosylation it is crucial to further explore and compare the physicochemical and biological properties of these two phenolic compounds In this study we demonstrate that glucosylation is a promising method for modification of phenolic compound and that αEG is superior over its parent eugenol in all of the tested aspects including physicochemical properties antioxidation activity and antimicrobial and antitumor activities These results strongly suggest that αEG as a novel prodrug may serve as a useful probe and potential therapeutic drug in both fundamental research and clinical application in the coming futureThis work was supported by the Natural Science Funds of Beijing University of Chemical Technology and State Key Laboratory of Microbial Technology China We also appreciate the assistance of proofreading and language correction provided by Mr Steve Zicari Department of Biological and Agricultural Engineering University of California Davis USA
