Peptide inhibitors of human HMG-CoA reductase as potential hypocholesterolemia agents

Abstract Hypercholesterolemia may lead to obesity and cardiovascular diseases. To prevent hypercholesterolemia, many drugs have been developed while searching for better drugs to treat hypercholesterolemia has never been ended. Other than small molecule drugs, peptide drugs are gaining more visibilities in many therapeutic areas. In the present study, we employed phage-display techniques to screen peptide inhibitors against human HMG-CoA reductase. The results indicate that the tetrapeptide PMAS inhibits hHMGR effectively (IC 50  = 68 μM), could be a lead compound to develop hypocholesterolemic agents.
