NCIt definition : The acetate salt of an antimycotic echinocandin lipopeptide, semisynthetically derived
from a fermentation product of the fungus Glarea lozoyensis. Caspofungin inhibits
1,3-beta-glucan synthase, resulting in decreased synthesis of beta(1,3)-D-glucan (an
essential component of the fungal cell wall), weakening of the fungal cell wall, and
fungal cell wall rupture. This agent is active against Aspergillus and Candida species.;
Alternative definition : NCI-GLOSS: A drug used to prevent or treat infections caused by a fungus (a type of
