FR-900109 is a new antibiotic obtained from fermentation broth of a streptomyces which was identified as Streptomyces prunicolor. Its elementary analysis and mass spectroscopic measurement suggest that the molecular formula is C₂₇H₃₂O₉. It has an ultraviolet absorption maximum at 254 nm. The antibiotic is active against Gram-positive bacteria. Acute toxicity in mice is very low.
