Vancomycin

Vancomycin INN ( /væŋkɵˈmaɪsɨn/) is a glycopeptide antibiotic used in the prophylaxis and treatment of infections caused by Gram-positive bacteria. Vancomycin was first isolated in 1953 at Eli Lilly, from a soil sample collected from the interior jungles of Borneo by a missionary. It is a naturally occurring antibiotic made by the soil bacterium Actinobacteria species Amycolatopsis orientalis (formerly designated Nocardia orientalis). It is a complex chemical compound and an example of a comparatively rare haloorganic natural compound, containing two covalently bonded chlorine atoms.
