Dehydroabietic acid (DAA) is a food‐derived terpenoid with various bioactivities. Our previous study has revealed that DAA activates peroxisome proliferator‐activated receptor‐γ (PPARγ) in luciferase assay and suppresses chronic inflammation in obese adipose tissues. In this study, we examined the effects of DAA on adipocyte differentiation. DAA treatment stimulated the adipocyte differentiation of 3T3‐L1 preadipocytes. The DAA treatment increased the mRNA expression levels of adipocyte differentiation marker genes such as aP2 , lipoprotein lipase ( LPL ), and PPARγ . In particular, the expression level of adiponectin , which is an adipocytokine with stimulatory effects on insulin sensitivity, was increased at both the mRNA and protein levels by the DAA treatment. Moreover, the DAA treatment stimulated insulin‐dependent glucose uptake into differentiated 3T3‐L1 adipocytes. These findings indicate that DAA stimulates adipocyte differentiation and insulin sensitivity in 3T3‐L1 cells, suggesting that DAA is a valuable food‐derived compound for the management of metabolic syndrome.
