Mechanism of action

Polyenes specifically target fungal membranes. They bind ergosterol, which is the principal sterol in fungal membranes as opposed to cholesterol found in host membranes. This interference creates a transmembrane channel and the resultant change in permeability allows leakage of intracellular components
