mi·to·my·cin (mi″to-miґsin) any of a group of antitumor antibiotics (e.g., mitomycin A, B, C) produced by Streptomyces caespitosus. [USP] mitomycin C, which acts as a bifunctional or trifunctional alkylating agent causing cross-linking of DNA and inhibition of DNA synthesis and is relatively phase-specific for the late G1 and early S phases of the cell cycle. It has activity against many types of carcinoma as well as chronic myelogenous leukemia, but because of its severe toxicity and myelosuppression it is usually used only for palliation in patients who have not responded to other treatment. Administered intravenously.
