Synthetic derivatives of chrysin and their biological activities

Chrysin is one of flavones constituents of Orocylumineicum vent . It has been a hot spot as a potential chemopreventive agent and as a natural molecule with numerous biological activities such as antioxidant, antitumor, antiviral, anti-hypertension, anti-diabetic, antibacterial, and so on in recent years. Because of its poor solubility, small intestinal absorption, and the rapid metabolism of glycosylation, a large number of efforts had been made by domestic and foreign researchers on designing its analogs and conjugates to obtain compounds with improved efficacy and selectivity for developing more active drugs for clinic. This article reviews the current research of studying on chrysin derivatives including their properties and possible applications. Additionally, this article also presents the basic information concerning chemical reactivity of chrysin, relevant to the synthesis of its derivatives.
