Scope Ginger exerts protective effects on obesity and its complications. Our objectives here are to identify bioactive compounds that inhibit adipogenesis and lipid accumulation in vitro, elucidate the anti-obesity effect of gingerenone A (GA) in diet-induced obesity (DIO), and investigate whether GA affects adipose tissue inflammation (ATI). Methods and results Oil red O staining showed that GA had the most potent inhibitory effect on adipogenesis and lipid accumulation in 3T3-L1 cells among ginger components tested at a single concentration (40 μM). Consistent with in vitro data, GA attenuates DIO by reducing fat mass in mice. This was accompanied by a modulation of fatty acid metabolism via activation of AMP-activated protein kinase (AMPK) in vitro and in vivo. Additionally, GA suppressed ATI by inhibiting macrophage recruitment and downregulating pro-inflammatory cytokines. Conclusion These results suggest that GA may be used as a potential therapeutic candidate for the treatment of obesity and its complications by suppressing adipose expansion and inflammation. Gingerenone A (GA), a polyphenol in ginger component, suppresses body weight gain induced by HFD, which primarily involves in a decrease in fat mass. Moreover, GA reduces HFD-induced macrophage infiltration and adipose tissue inflammation by modulating adipokines in EWAT. These results suggest that GA may be used as a potential therapeutic candidate for the treatment of obesity and its complications by suppressing an increase in fat mass and adipose inflammation.
