pimaricin usage and synthesis

description	pimaricin (also known as natamycin, inn) belongs to a naturally occurring antifungal agent produced through the fermentation of the bacterium streptomyces natalensis. it is a kind of macrolide polyene antifungal used for the treatment of fungal keratitis, which is a kind of eye infection. in medical field, it can be used for the treatment of various kind of fungal infections caused by candida, aspergillus, cephalosporium, fusarium, and penicillium. in food industry, it can be used as a natural preservative to prevent fungal outgrowth. its mechanism of action is through binding to the ergosterol in the plasma membrane of fungi, inhibiting the process of ergosterol-dependent fusion of vacuoles and membrane fusion, further inhibiting the fungal growth. it also inhibit the transport of amino acid and glucose through inhibiting membrane transport proteins.

uses	analgesic, antimigraine
uses	pimaricin is a macrocyclic tetraene originally isolated from streptomyces natalensis in 1957. pimaricin exhibits broad spectrum antifungal activity against yeast and filamentous fungi by binding specifically to ergosterol to block fungal growth. unlike the related polyenes, nystatin and filipin, pimaricin does not change the permeability of the plasma membrane. pimaricin is used in the food industry for surface treatment of cheeses as a mould inhibitor.
