Antibiotic baumycin complex and components thereof
摘要:
A novel anthracycline antibiotic complex designated herein as baumycin complex is produced by fermentation of a baumycin-producing strain of Streptomyces, e.g. Streptomyces coeruleorubidus ME 130-A4 (FERM-P3540, ATCC 31276). The complex and four bioactive components thereof designated baumycin A.sub.1, A.sub.2, B.sub.1 and B.sub.2 are useful as antibacterial and antitumor agents.
