ABSTRACT:
A novel antitumor antibiotic designated herein as BBM-2040 is produced by fermentation of Streptomyces sp. strain J576-99 (ATCC 39143). BBM-2040, which may be recovered from the fermentation broth in either a desmethanol (BBM-2040B) or methanol-adduct (BBM-2040A) form, inhibits gram-positive and acid-fast bacteria and inhibits the growth of tumors such as P388 leukemia in mice.
