DescriptionLandomycin B belongs to the class of organic compounds known as anthraquinones. These are organic compounds containing either anthracene-9,10-quinone, 1,4-anthraquinone, or 1,2-anthraquinone. Landomycin B is found in Streptomyces and Streptomyces cyanogenus. It was first documented in 1990 (PMID: 2358402). Based on a literature review very few articles have been published on Landomycin B (PMID: 23047245) (PMID: 26484067) (PMID: 30486371) (PMID: 17139690).
