  • Patent number: 10464977
    Abstract: Provided herein are synthetic peptides or synthetic fragments thereof based on a Histatin-5 peptide, for example with a sequence DSHAKRHHGYKRKFHEKHHSHRGY (SEQ ID NO: 1). The synthetic peptides or synthetic fragments have at least one substituted amino acid that is arginine and/or leucine to increase resistance to proteolytic degradation by a microbe, such as a fungus. The synthetic peptides or synthetic fragments thereof may be contained in a hydrogel. Also provided are methods for treating or preventing a pathophysiological condition via topical administration of the synthetic peptide or fragments. The pathophysiological condition may be a fungal or bacterial infection including associated inflammation or a chronic condition.
    Type: Grant
    Filed: April 11, 2017
    Date of Patent: November 5, 2019
    Assignees: University of Maryland, Baltimore, University of Maryland, College Park
    Inventors: Mary Ann Jabra-Rizk, Amy J. Karlsson, Svetlana Pavlova Ikonomova

  • Patent number: 9168329
    Abstract: The present invention is directed to the design, synthesis and use of various ?-peptides exhibiting antifungal activity. The ?-peptides are relatively short in length, adopt globally amphiphilic conformations, and cause little lysis of human red blood cells at concentrations that kill Candida albicans, a common human fungal pathogen.
