Three new metabolites were isolated from a pathogenic bacterium, Nocardia brasiliensis IFM 0075 strain, a producer of a new anthracycline antibiotic (SO-075R1) and its mutant strain (IFM 0075-13-1). The structural studies showed that they are reduced anthracyline related compounds. Some biosynthetic routes of these matabolites were discussed.
