Abstract: Methods of inhibiting leukocyte O2? production and attracting leuckocytes using specific peptides are disclosed. These peptides include the proline-arginine (PR)-rich antimicrobial peptide known as PR-39 and truncated analogs thereof. These peptides can be used as medicaments that fight infection by attracting leukocytes to a wound site, yet restrict tissue damage at the wound site caused by excessive oxygen radicals produced by these leukocytes.

Abstract: An in vivo method of reducing reperfusion injury in a mammal resulting from reperfusion of a temporarily occluded blood vessel which comprises the steps of administering into the mammal's bloodstream an effective amount of a proline /arginine rich peptide such as PR-39 (SEQ ID NO: 1). The method has particular application in surgical procedures such as coronary bypass and organ transplantation surgery and where reperfusions occur subsequent to a spontaneous occlusion. Preferred peptides have up to about 50 amino acid residues with a plurality of --PXXP-- sequences.

Abstract: New antimicrobial truncated peptides are disclosed which are based upon a known peptide, PR-39 (SEQ ID NO: 1) but which contain a lesser number of amino acid residues yet still retain antimicrobial activity. The most preferred peptide compound is PR-26, SEQ ID NO: 2. The invention also relates to a method of inhibiting microbial growth by administering an effective amount of a peptide in accordance with the invention.
