    Caspofungin Acetate


    Caspofungin Acetate is a lipopeptide echinocandin antifungal which specifically targets the fungal cell membrane. It is semisynthetically derived from a fermentation product of the fungus Glarea lozoyensis.  As  a β-1,3-D-glucan synthesis antagonist, the compound is used to study the effect of environmental and chemical stress on fungal survival.  Caspofungin is an analog of pneumocandin B0.  Caspofungin Acetate is sparingly soluble in water and slightly soluble in ethanol.

    Mechanism of Action Caspofungin acts as an inhibitor of β(1,3)-D-Glucan synthase, an enzyme required for cell wall synthesis. Inhibition of this enzyme results in a disruption of the fungal cell wall integrity.
    Spectrum Caspofungin Acetate is effective against yeasts and molds including Candida and Aspergillus spp.
