    摘要: An anthracycline compound, ditrisarubicin, of the formula: ##STR1## wherein R represents one of the following substituents (A), (B), and (C): ##STR2## is produced by a process which comprises cultivating a strain of Streptomyces in a suitable culture medium under aerobic conditions, said strain having the ability to produce the anthracycline compound, ditrisarubicin, and then recovering the anthracycline compound, ditrisarubicin, from the cultured medium. This ditrisarubicin, or an acid addition salt of the ditrisarubicin, can be contained as the active ingredient in antitumor agents and in pharmaceutical compositions for treatment of infections induced by gram-positive microorganisms, whereby good results are attainable.
