Pimaricin, also known as natamycin, is a polyene antifungal agent widely used as a preservative in the food industry, particularly in cheese, sausages, processed meats, bakery products, and beverages to prevent the growth of mold and yeast. It is also applied in ophthalmology as an antifungal agent to treat fungal infections of the eye, such as keratitis, and in some cases for oral or systemic infections in immunocompromised patients. In agriculture, pimaricin is utilized as a fungicide to protect crops from fungal diseases, ensuring healthier yields. Additionally, it finds application in the preservation of cosmetics and pharmaceuticals, safeguarding them from microbial contamination. Its effectiveness against a broad spectrum of fungi makes it a valuable component in various antifungal formulations.
