[Originator]

Mitomycin,Medac,W. Germany,1960
[Indications]

Mitomycin (mitomycin C, Mitocin-C, Mutamycin) is an antibiotic that is derived from a species of Streptomyces. It is sometimes classified as an alkylating agent because it can covalently bind to and cross-link DNA. Mitomycin is thought to inhibit DNA synthesis through its ability to alkylate double-strand DNA and bring about interstrand cross-linking. There is evidence that enzymatic reduction by a reduced nicotinamide– adenine dinucleotide phosphate (NADPH) dependent reductase is necessary to activate the drug.
The drug is rapidly cleared from serum after intravenous injection but is not distributed to the brain.
[Manufacturing Process]

The commercial production of mitomycin involves the preparation of mitomycin-containing broths by culturing a mitomycin-producing organism, e.g. Streptomyces caespitosus, in suitable media as described at length in the literature. At the end of the fermentation cycle the whole broth is usually centrifuged, filtered or otherwise treated to separate the solids (mycelia) from the supernatant which contains substantially all of the antibiotic activity.
In commercial processes there is usually a period of time intervening between the end of the fermentation cycle and the time at which the mycelia is actually removed from the broth; such a period may range from several minutes to several hours in length and may be due to a number of factors, e.g., the time necessary to conduct the actual centrifugation or filtration of large quantities of broth, or the time involved in waiting for equipment to become available for use. In the commercial preparation of mitomycin, the mitomycin-containing whole broths decrease rapidly in potency during the time following the completion of the fermentation cycle and prior to the removal of the mycelia. It has been observed that a whole broth will lose substantially all of its mitomycin activity within about 6 hours at room temperature and within about 24 hours at 10°C. It has, however, been discovered, as described in US Patent 3,042,582, that in the process for the recovery of mitomycin C from mitomycin C-containing whole broth, the step of adding about 0.1 wt % with whole broth of sodium lauryl sulfate to the whole broth at the completion of the fermentation cycle substantially eliminates such destruction of mitomycin C by mitase.
[Brand name]

Mutamycin (Bristol-Myers Squibb);Mytozytrex (SuperGen).
[Therapeutic Function]

Cancer chemotherapy
[Biological Activity]

Antibiotic and antitumor agent. Covalently binds DNA forming intra- and interstrand crosslinks. Inhibits DNA synthesis.
[Clinical Use]

Mitomycin has limited palliative effects in carcinomas of the stomach, pancreas, colon, breast, and cervix.
[Drug interactions]

Potentially hazardous interactions with other drugs
Antipsychotics: avoid with clozapine (increased risk of agranulocytosis).
Live vaccines: risk of generalised infections - avoid.
[Environmental Fate]

Mitomycin C is naturally produced by S. caespitosus, a microorganism found in soil and decaying vegetation. As a compound potentially released in commercial solid waste or in spill or container residue, mitomycin C is not thought to persist in soil and water. Calculations based on its hydrolysis rate in water at 25 ℃ show a half-life of 12.9 days. It is readily soluble in water, so mobility in groundwater is high. Mitomycin persistence in air is low and bioaccumulation is low.
[Metabolism]

Mitomycin is administered IV in the treatment of disseminated adenocarcinoma of the stomach or pancreas, and it has been used intravesically in superficial bladder cancer. Biotransformation pathways are saturable, and approximately 10% of an administered dose is eliminated unchanged via the kidneys.
[storage]

+4°C
[Purification Methods]

Mitomycin C forms blue-violet crystals from *C6H6/pet ether. It is soluble in Me2CO, MeOH and H2O, moderately soluble in *C6H6, CCl4 and Et2O but insoluble in pet ether. It has UV max at 216, 360 and a weak peak at 560nm in MeOH. [Stevens et al. J Med Chem 8 1 1965, Shirahata & Hirayama J Am Chem Soc 105 7199 1983, Beilstein 25 III/IV 516.]
[Toxicity evaluation]

Mitomycin C inhibits DNA synthesis and cross-links DNA at the N6 position of adenine and at the O6 and N2 positions of guanine. In addition, single-strand breakage of DNA is caused by reduced mitomycin C (this can be prevented by free radical scavengers). Its action is most prominent during the late G1 and early S phases of the cell cycle. Mitomycin C can inhibit RNA and protein synthesis at high concentrations. Mytomycin C is an aneuploidy-inducing agent. Oxygen and radiation therapy have been shown to enhance the development of toxicity.

[description]

Mitomycin C (MMC), an antineoplastic antibiotic derived from Streptomyces caespitosus or Streptomyces lavendulae, is a cell cycle-specific alkylating agent, inhibits DNA synthesis through covalent mitomycin C-DNA adduct with EC50 values of 0.14μM in PC3 cells. Therefore, it was served as a chemotherapeutic agent that has demonstrated its antitumor activity and has been used widely in treatment of various cancers.
Although it is active against a wide variety of tumors, newer agents have largely replaced MMC except in anal cancer; outside of the United States, MMC is infrequently used for treatment of advanced non-small cell lung cancer (NSCLC), and breast cancer.
[Chemical properties]

It is a crystalline powder or a powder with blue-purple shiny crystal. Its solid state is stable, while easily deactivated in acidic and alkaline solution. Mp> 360 ℃; the maximum absorption wavelength in methanol is 216nm, 360nm and 560nm.The maximum absorption wavelength in aqueous solution is 365nm ± 2nm. This product is soluble in water, methanol, acetone and ethyl acetate and other organic solvents, slightly soluble in benzene, ether and carbon tetrachloride, insoluble in petroleum ether. Highly toxic chemical, LD50 (rat, oral) 14mg/kg. Tests show that this product has potential carcinogenic effects on experimental animals.
[Side effects]

As with many other chemotherapeutic agents, most of the side effects of Mitomycin C (MMC)  are dose-related, including myelosuppression (which is typically delayed in onset), nausea, vomiting, diarrhea, stomatitis, dementia, and alopecia. Pulmonary toxicity associated with MMC is unpredictable, but more likely to occur at higher doses.
The following side effects are common (occurring in greater than 30%) for patients taking Mitomycin C:
Low blood counts.  Your white and red blood cells and platelets may temporarily decrease.  This can put you at increased risk for infection, anemia and/or bleeding.  The nadir counts are delayed with this drug.
Nadir: Meaning low point, nadir is the point in time between chemotherapy cycles in which you experience low blood counts.
Onset: 3 weeks
Nadir: 4-6 weeks
Recovery: 6-8 weeks
Mouth sores
Poor appetite
Fatigue
These side effects are less common side effects (occurring in about 10-29%) of patients receiving Mitomycin C:
Nausea and vomiting, usually mild
Diarrhea
Hair loss
Bladder inflammation (urinary frequency, burning, cramping, pain)-seen with intravesical (into the bladder) therapy.
[Uses]

(1) It is a cell division inhibitors, nucleic acid inhibitors and phage inducer; an anti-tumor drugs in clinical use.
(2) This drug has a broad anti-tumor spectrum, and effective for gastric cancer, breast cancer. It has a certain effect on lung cancer, liver cancer, malignant lymphoma, Hodgkin's disease, reticular cell sarcoma, uterine cancer, leukemia, intestinal cancer and pancreatic cancer, but with a short remission. Combination with urokinase can improve the efficacy. The goods exert its function quickly, but the number of operators is not high, and it has a high toxicity. The goods and bleomycin as well as its derivatives ——doxorubicin are anti-cancer drugs of antibiotic which can disrupt DNA. It can depolymerize DNA in the cell, inhibit DNA replication in proliferating cell. The LD50 of intravenous injection of mice is 5ml/kg. It acts as an anticancer drugs, commonly used in the treatment of digestive system cancers.
