13-Deoxycarminomycin, a New Biosynthetic Anthracycline

Abstract
A new antitumor antibiotic, 13-deoxycarminomycin (3), was isolated from the anthracycline complex produced by Streptomyces peucetius var. carminatus (ATCC 31502), a biochemical mutant of S. peucetius var. caesius, the doxorubicin-producing microorganisms. The new anthracycline (3) showing antibacterial and cytotoxic activity in vitro, was active against P-388 murine leukemia.
