Natamycin is a macrolide antifungal used to treat fungal infections of the eye. Amphoteric macrolide antifungal antibiotic from Streptomyces natalensis or S. chattanoogensis.
- Mechanism
- Curator reviewed
Like other polyene antibiotics, Natamycin inhibits fungal growth by binding to sterols. Specifically, Natamycin binds to ergosterol in the plasma membrane, preventing ergosterol-dependent fusion of vacuoles, as well as membrane fusion and fission. This differs from the mechanism of most other polyene antibiotics, which tend to work by altering fungal membrane permeability instead.
