Description
Curator's Comment: description was created based on several sources, including: https://en.wikipedia.org/wiki/Natamycin http://www.life-worldwide.org/fungal-diseases/natamycin http://www.drugbank.ca/drugs/DB00826

Natamycin (Pimaricin, Pimafucin, Natadrops, Natacyn) is a polyene antifungal agent originally isolated from Streptomyces natalensis found in a soil sample from Natal, South Africa. Natamycin was discovered in DSM laboratories in 1955. Similar to other polyenes, natamycin binds to ergosterol in the fungal cell membrane. Natamycin blocks fungal growth by binding specifically to ergosterol with¬out permeabilizing the membrane where it inhibits vacuole fusion at the priming phase and interferes with membrane protein functions. Natamycin is also used in the food industry as an effective preservative. Natamycin is active against most Candida spp. Aspergillus spp., Fusarium spp. and other rarer fungi that cause keratitis. Secondary or acquired resistance is probably rare, but not extensively studied. Natamycin is not effective in vitro against gram-positive or gram-negative bacteria. Topical administration appears to produce effective concentrations of natamycin within the corneal stroma but not in intraocular fluid. Natamycin is poorly soluble in water and not absorbed through the skin or mucous membranes, including the vagina. Very little is absorbed through the gastrointestinal tract. After ocular application, therapeutic concentrations are present within the infected cornea, but not in intra-ocular fluid Natamycin may cause some irritation on skin or mucous membranes
