Hyperlipidemia is a major risk factor for cardiovascular diseases. In this study, we investigated the potential effects of cordycepin (3'-deoxyadenosine), a bioactive component of the fungus Cordyceps militaris, on hyperlipidemia. We found that in male Syrian golden hamsters fed a high-fat diet (HFD), daily administration of cordycepin effectively reduced the accumulation of serum total cholesterol (TC), triglycerides (TG), and low-density lipoprotein cholesterol (LDL-c) and suppressed HFD-associated increases in relative retroperitoneal fat. It also increased the levels of phospho-AMP-activated protein kinase (AMPK) and phospho-acetyl-CoA carboxylase (phospho-ACC) in liver and retroperitoneal adipose tissues In HePG2 cells, cordycepin stimulated robust concentration- and time-dependent AMPK activation that correlated with the activation of ACC and the suppression of lipid biosysthesis. However, pretreatment with compound C, a specific inhibitor of AMPK, substantially abolished the effects of cordycepin prevents hyperlipilemia via activation of AMPK. Experiment on abnormal metabolic mice indicated that cordycepin can also improve insulin sensitivity effectively
