Literature References: Antineoplastic antibiotic produced by cultures of actinomycin C-elaborating strains of Streptomyces, such as Streptomyces BOP 476 (NRRL 2580) and Streptomyces chrysomallus (NRRL 2250). Considered to be a derivative of actinomycin C2; amino acid analysis indicates that the prolines present in actinomycin C2 are substituted by sarcosine in actinomycin F1.
