Description


Natamycin is only found in individuals that have used or taken this drug. It is an amphoteric macrolide antifungal antibiotic from Streptomyces natalensis or S. chattanoogensis. It is used for a variety of fungal infections, mainly topically. [PubChem]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. Primarily used as a surface treatment to prevent growth of yeasts and moulds, especies on cheese. Permitted agent in USA for surface treatment of cheeses as mould-inhibitor. No reported allergic reactions and it has GRAS status G - Genito urinary system and sex hormones > G01 - Gynecological antiinfectives and antiseptics > G01A - Antiinfectives and antiseptics, excl. combinations with corticosteroids > G01AA - Antibiotics A - Alimentary tract and metabolism > A01 - Stomatological preparations > A01A - Stomatological preparations > A01AB - Antiinfectives and antiseptics for local oral treatment A - Alimentary tract and metabolism > A07 - Antidiarrheals, intestinal antiinflammatory/antiinfective agents > A07A - Intestinal antiinfectives > A07AA - Antibiotics D - Dermatologicals > D01 - Antifungals for dermatological use > D01A - Antifungals for topical use > D01AA - Antibiotics S - Sensory organs > S01 - Ophthalmologicals > S01A - Antiinfectives > S01AA - Antibiotics D000890 - Anti-Infective Agents > D000900 - Anti-Bacterial Agents D000890 - Anti-Infective Agents > D000935 - Antifungal Agents Natamycin (Pimaricin) is a macrolide antibiotic agent produced by several Streptomyces strains. Natamycin inhibits the growth of fungi via inhibition of amino acid and glucose transport across the plasma membrane. Natamycin is a food preservative, an antifungal agent in agriculture, and is widely used for fungal keratitis research[1][2].
