ABSTRACT
Trifuhalol A, a fucol-type phlorotannin, was extracted and identified from the brown algae Agarum cribrosum. The total yield and purity of trifuhalol A from A. cribrosum were 0.98% and 86%, respectively. Trifuhalol A at 22 and 44 µM inhibited lipid accumulation in human primary adipocytes. Consistently trifuhalol A suppressed the expression of adipogenesis-related genes, such as proliferator-activated receptor-gamma (PPAR-γ), CCAAT/enhancer-binding protein-alpha (C/EBP-α), fatty acid synthase (FAS), and sterol regulatory element-binding protein-1 (SREBP-1), in a dose-dependent manner. Trifuhalol A increased the level of proteins such as wingless/integrated (Wnt)10b, nuclear-ß-catenin, total-ß-catenin, phospho-AMP-activated protein kinase (pAMPK), and phospho-liver kinase B1 (pLKB1) as well as the expression of genes such as Wnt10b, Frizzled 1, and low-density lipoprotein receptor-related protein 6 (LRP6). Additionally, trifuhalol A decreased the expression of the glycogen synthase kinase-3beta (GSK3ß) gene. These results suggest that trifuhalol A reduces fat accumulation in human adipocytes via the Wnt/ß-catenin- and AMPK-dependent pathways.
