Abstract: Two new anthracycline antibiotics have been isolated in study of a rubomycin complex produced by the mutant strain Streptomyces coeruleorubidus, var. 2679. Both compounds are daunomycinone disaccharides, whose carbohydrate part is presented by daunoseamine glycosylated at 4'-position with 2-deoxyfucopyranose (rubomycin M) or with 2,6-dideoxygulopyranose (rubomycin N).
