In addition, the prenyl group has been proposed as an active group to enhance the osteogenesis process in recent years of some flavonoid compounds, including genistein prenylated derivatives (6-prenylgenistein, 8-prenylgenistein and 6,8-prenylgenistein) which have been shown to better stimulate osteoblastic proliferation, differentiation, and mineralization in UMR 106 cells than genistein itself [17].
