Abstract

  We found that enterostatin (VPDPR), an anorexigenic peptide for a high-fat diet, significantly reduces serum cholesterol levels after oral administration of 100 mg/kg for 3 days in mice fed a high cholesterol-cholic acid diet. DPR, a peptide fragment of VPDPR, also had hypocholesterolemic activity at a dose of 50 mg/kg. Food intake was not suppressed under these dietary conditions. Fecal excretion of cholesterol and bile acids was increased significantly by both VPDPR and DPR. Interestingly, DPR induced hypocholesterolemic effects just two hours after a single oral administration at a dose of 100 mg/kg.<br>
