Leslie H. Kondejewski has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Polypeptide compositions formed using a coiled-coil template and methods of use
    Patent number: 7262272
    Abstract: The invention relates to the use of constrained coiled-coil polypeptides to mimic ?-helical structural elements of native proteins. These constrained peptidyl mimetics are used to generate and/or identify ligands which selectively bind the ?-helical segment contained in the native protein.
    Type: Grant
    Filed: February 15, 2005
    Date of Patent: August 28, 2007
    Assignee: The Governors of the University of Alberta
    Inventors: Leslie H. Kondejewski, Randall T. Irvin, Robert S. Hodges

  • Antimicrobial peptide compositions and method
    Patent number: 6358921
    Abstract: The invention concerns antimicrobial cyclic peptides and peptide analogs having relatively low hemolytic activity. Peptides of the invention are effective in killing and/or inhibiting growth of a number of microorganisms, including gram-positive bacteria, gram-negative bacteria, fungi and mycoplasma. Also disclosed are methods for inhibiting or killing such microorganisms, and therapeutic preparations for such inhibiting or killing.
