title: New anthracycline metabolites from mutant strains of Streptomyces galilaeus MA144-M1. II. Structure of 2-hydroxyaklavinone and new aklavinone glycosides.
abstract: Four blocked mutants of aclacinomycin-producing Streptomyces galilaeus MA144-M1 produced new anthracyclinones; 2-hydroxyaklavinone, its non-esterified analog and 2-hydroxy-7-deoxyaklavinone, several new anthracyclines; 2-deoxyfucosyl-2-deoxyfucosyl-rhodosaminylaklavinone (MA144 U1), 2-deoxyfucosyl-rhodosaminylaklavinone (MA144 U2) and five aklavinone glycosides devoid of amino sugar, designated as MA144 U5, U6, U7, U8 and U9.
