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.
