PROCESS FOR PRODUCING CITOSTATIC ANTIBIOTIC COMPLEXES

摘要

An antitumor antibacterial complex having a quinoline nucleas referred to as BBM-928 is described which is produced by microbiological fermentation under controlled conditions using a species of actinomycetes. The bioactive components of the complex have pronounced antitumor activity and are moderately to weakly active against gram-positive and acid fast bacteria but practically inactive against gram- negative bacteria and fungi. Based on median survival time, the component designated BBM-928A is substantially more active than mitomycin C by a factor of 10 to 300 fold against intraperitoneally implanted mouse tumors.
