4--5-7-trihydroxy-3-6-dimethoxyflavone and sakuranetin

Ten new isoprenylated flavonol derivatives, dodoviscins A-J (1-10), and seven known compounds (11-17) were isolated from the aerial parts of Dodonaea viscosa. Compounds 1, 2, 4, 5, 7-9, 5,7,4'-trihydroxy-3',5'-bis(3-methyl-2-buten-1-yl)-3-methoxyflavone (11), 5,7,4'-trihydroxy-3',5'-bis(3-methyl-2-buten-1-yl)-3,6-dimethoxyflavone (12), 5,7,4'-trihydroxy-3'-(4-hydroxy-3-methylbutyl)-5'-(3-methyl-2-buten-1-yl)-3,6-dimethyoxyflavone (13), sakuranetin (14), and blumeatin (15) promoted adipocyte differentiation as characterized by increased triglyceride levels in 3T3L1 cells. Compounds 1, 13, and 15 also enhanced the accumulation of lipid droplets and induced upregulation of the expression of the adipocyte-specific genes aP2 and GLUT4.
