US Patent 12012440 Compositions and methods for treatment of fungal infections

Peptide analogs of a θ-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 θ-defensin analogs are protective at concentrations where naturally occurring θ-defensins have no apparent effect, and include a core set of structural and sequence features not found in native θ-defensins.
