摘要
Here, we describe amentoflavone-type biflavonoids, which were isolated from natural sources and were found to inhibit beta-secretase (BACE-1). The structure-activity relationship was studied, and compounds 1-8, 10, 17, and 18 showed BACE-1 inhibitory activity. Among these compounds, 2,3-dihydroamentoflavone 17 and 2,3-dihydro-6-methylginkgetin 18 exhibited potent inhibitory effects with IC(50) values of 0.75 and 0.35 microM, respectively.
