The rubomycin complex produced by Streptomyces coeruleorubidus 4-157 was studied and the two novel anthracyclines i.e. rubomycins F and H were isolated. The study of the physicochemical properties of the novel antibiotics in comparison with rubomycin C (daunomycin) and the specially prepared 3'-N-carbmethoxyrubomycin C showed that rubomycin F was 3'-N-carbethoxydaunomycin and rubomycin H was 3'-N-carbmethoxydaunomycin. Therefore, rubomycins F and H are novel representatives of natural anthracyclines undescribed previously.
