Mitomycin is one of the older chemotherapy drugs, which has been around and in use for decades. It is an antibiotic which has been shown to have antitumor activity. Mitomycin selectively inhibits the synthesis of deoxyribonucleic acid (DNA). The guanine and cytosine content correlates with the degree of mitomycin-induced cross-linking. At high concentrations of the drug, cellular RNA and protein synthesis are also suppressed. Mitomycin has been shown in vitro to inhibit B cell, T cell, and macrophage proliferation and impair antigen presentation, as well as the secretion of interferon gamma, TNFa, and IL-2.

Mechanism of Action

Mitomycin is activated in vivo to a bifunctional and trifunctional alkylating agent. Binding to DNA leads to cross-linking and inhibition of DNA synthesis and function. Mitomycin is cell cycle phase-nonspecific.




Oral, mouse: LD50 = 23 mg/kg; Oral, rat: LD50 = 30 mg/kg. Symptoms of overdose include nausea and vomiting.

Biotrnasformation / Drug Metabolism

Primarily hepatic, some in various other tissues.


Mitomycin is contraindicated in patients who have demonstrated a hypersensitive or idiosyncratic reaction to it in the past. Mitomycin is contraindicated in patients with thrombocytopenia, coagulation disorder, or an increase in bleeding tendency due to other causes.
