ISOLATION, CHARACTERIZATION, AND STRUCTURE OF RABELOMYCIN, A NEW ANTIBIOTIC

Abstract

Rabelomycin, a new benz [a] anthraquinone antibiotic, has been isolated from fermentation broths of Streptomyces olivaceus ATCC 21, 549. It is active against gram-positive microorganisms. Rabelomycin loses water easily when treated with acid. Structures I and III have been proposed for rabelomycin and its dehydration product, respectively.
