Abstract
A new antitumor antibiotic designated herein as BMY-28121 is produced by fermentation of Streptomyces albus strain K731-113 (ATCC 39897). BMY-28121, which may be recovered from the fermentation broth in either its natural free hydroxy form (BMY-28121A) or methyl ether form (BMY-28121B), inhibits gram-positive bacteria and anaerobes and inhibits the growth of mammalian tumors such as P-388 leukemia, L-1210 leukemia and B16 melanoma.
