  • Publication number: 20240108702
    Abstract: Methods for treating and/or SARS-CoV-2 infection are described that inhibit viral replication, multiple protease activities, and provide anti-inflammatory activity. Such activities can be provided by a single species, such as a naturally occurring cyclic peptide.
    Type: Application
    Filed: January 12, 2022
    Publication date: April 4, 2024
    Inventors: Michael E. Selsted, Dat Q. Tran, Patti Tran, Justin B. Schaal, Virginia Basso, Prasad Tongaonkar
  • Publication number: 20230072433
    Abstract: Novel peptide analogs of a ?-defensin have been developed that provide a biphasic effect in treating disseminated fungal disease and/or associated septic shock. These analogs are active at concentrations below those needed to provide a fungicidal effect, and function by initially mobilizing effector cells of the immune system to address the infective organism followed by regulation of the immune system to down regulate the inflammatory response. These novel ?-defensin analogs are protective at concentrations where naturally occurring ?-defensins have no apparent effect, and include a core set of structural and sequence features not found in native ?-defensins.

  • Publication number: 20230038720
    Abstract: Peptide analogs of ?-defensins have been developed that are effective in treating multi-drug resistant microbial infections when used at concentrations below those needed to provide a microbicidal effect. These peptides were found to modulate host defense mechanisms to increase clearance of microbial pathogens, enhance phagocytic activity, and enhance neutrophil recruitment while reducing inflammation.

  • Publication number: 20210261623
    Abstract: Uses of novel peptide analogs of a ?-defensin that have been developed which provide a biphasic effect in treating infection and/or sepsis are described. These analogs are active at concentrations below those needed to provide a bactericidal or bacteriostatic effect, and function by initially recruiting effector cells of the immune system to address the infective organism followed by regulation of the immune system to down regulate the inflammatory response characteristic of sepsis and septic shock. These novel ?-defensin analogs are protective at concentrations where naturally occurring ?-defensins have no apparent effect, and include a core set of structural and sequence features not found in native ?-defensin.
