Overview

Leucomycin A5 is a major metabolite of the leucomycin complex, a family of closely related macrocyclic lactone antibiotics produced by|Streptomyces kitasatoensis|and discovered in 1953. Leucomycin A5 is one of the more potent antibiotics of the complex. Leucomycin complex (kitasamycin) is used as an animal health product for control of Gram positive bacteria, Gram negative cocci,|leptospira|and|mycoplasma|. Little is known about the activity of individual analogues within the complex as their limited availability has restricted investigation.
