  • Publication number: 20230364067
    Abstract: Enfumafungin derivative triterpenoid antifungal compounds are used to treat or prevent fungal infections occurring in or under acidic conditions where the pH is lower than about 7, due to their unexpected, enhanced efficacy under such conditions. The enfumafungin derivative triterpenoids (or pharmaceutically acceptable salts or hydrates thereof) are inhibitors of (1,3)-?-D-glucan synthesis and are useful in the treatment or prevention of yeast or mold infections that occur in anatomic areas having a low pH, such as the vaginal cavity, or under acidic local environment conditions such of those seen in fungal abscesses, empyema, or upper gastrointestinal tract infections.

  • Publication number: 20230149376
    Abstract: Enfumafungin derivative triterpenoid antifungal compounds are used to treat and/or prevent Pneumocystis pneumonia (PCP) due to their unexpected efficacy against Pneumocystis spp. including their ability to reduce the lung burden of cyst and trophic forms of this fungi. The enfumafungin derivative triterpenoids (or pharmaceutically acceptable salts or hydrates thereof) are inhibitors of (1,3)-?-D-glucan synthesis and are useful in the treatment and/or prevention of PCP since they demonstrate potent activity against Pneumocystis spp. in in vivo models, exhibit adequate tissue penetration into lungs, and are well tolerated.

  • Publication number: 20220211684
    Abstract: Enfumafungin derivative triterpenoid antifungal compounds are used to decolonize fungi from anatomic areas of subjects colonized by fungi. The enfumafungin derivative triterpenoids (or pharmaceutically acceptable salts or hydrates thereof) are inhibitors of (1,3)-?-glucan synthesis and can decolonize Candida auris from body sites such as skin and mucosa. Subjects who would benefit from such decolonization include individuals colonized by Candida auris who previously suffered a Candida auris infection and favor relapse and/or may transmit the fungus to other individuals who may be susceptible.

  • Publication number: 20220202833
    Abstract: The present invention relates to the use of enfumafungin derivative triterpenoid antifungal compounds in combination with other antifungal agents such azoles, polyenes, lipopeptides, and allylamides to treat fungal diseases. More particularly, the invention relates to antifungal combinations of enfumafungin derivative triterpenoids which are inhibitors of (1,3)-?-D-glucan synthesis, in combination with other antifungal agents such as mold-active agents that have activity against molds, including but not limited to voriconazole, isavuconazole, posaconazole, itraconazole and amphotericin B, for the treatment and/or prevention of infections caused by molds.

  • Publication number: 20220117948
    Abstract: Enfumafungin derivative triterpenoid antifungal compounds are used to treat osteo-articular fungal infections, due to their unexpected bone tissue penetration and associated efficacy for such infections. The enfumafungin derivative triterpenoids (or pharmaceutically acceptable salts or hydrates thereof) are inhibitors of (1,3)-?-D-glucan synthesis and are useful in the treatment of yeast or mold infections that occur in osteo-articular structures such as osteomyelitis, spondylodiscitis, and arthritis.
