title: New anthracyclinone metabolites from two blocked mutants of Streptomyces galilaeus MA144-M1.
abstract: Two blocked mutants of the aclacinomycin-producing Streptomyces galilaeus MA144-M1 produced new anthraquinones and anthracyclinones. The mutant ANR-58 produced compounds 58A, 58B, 58C (7-deoxy-2-hydroxyaklavinone), 58D (2-hydroxyaklavinone) and 58WR. All these compounds have the 2-hydroxyl group. The mutant ANR-665 produced compounds 665A and 665B. The compounds 58A, 58B and 665A have an anthraquinone skeleton.
