We report an application of the principle of multivalency to create new antimicrobial agents using the reactive polymaleic anhydride (PMA) chain to link antimicrobial tetrapeptides to afford multivalent variants containing ∼40 monomer units. Relative to the free peptides, the product shows a 10-fold improvement in IC50 without provoking more severe hemolysis of red blood cells. Thus, multivalency or poly valency may offer a route to enhance the activity of antimicrobial peptides.
