Ascomycin 19-epimer is a stereoisomer of ascomycin (immunomycin). Ascomycin was isolated in the early sixties as a fermentation product of Streptomyces hygroscopicus var. ascomycetus and probed for its antifungal activity. Ascomycin derivatives represent a novel class of anti-inflammatory macrolactams currently under development for the treatment of skin diseases.

Originator

Curator's Comment: Ascomycin, an antifungal antibiotic, was isolated by Arai et al. Originator of ascomycin 19-epimer is unknown.
