White crystals or powder.
[Reactivity Profile]

MYLERAN(55-98-1) is an alkylating agent which hydrolyzes in water. . Strong reducers may yield hydrogen sulfide.
[Air & Water Reactions]

This compound is an alkylating agent which hydrolyzes in water. .
[Hazard]

Extremely toxic, carcinogen, clastogenic, teratogenic, immunosuppressive, delayed bone marrow aplasia, cataracts, pigmentation, pulmonary thrombosis, cardiotoxic effects, thrombocytopenia.
[Fire Hazard]

Flash point data for this chemical are not available. MYLERAN is probably combustible.
[Description]

Chemically, busulfan is classified as an alkyl sulfonate. One or both of the methylsulfonate ester moieties can be displaced by the nucleophilic N7 of guanine, leading to monoalkylated and cross-linked DNA. The extent of alkyl sulfonate–mediated DNA interstrand cross-linking has been shown to vary with the length of the alkyl chain between sulfonate esters, with the tetramethylene-containing busulfan showing less interstrand cross-linking capability than hexamethylene, methylene, or octamethylene analogues. Intrastrand cross-linking also occurs, preferentially at 5′-GA-3′ but also at 5′-GG-3′ sequences. Alkylation of Cys sulfhydryl groups is yet another mechanism of cytotoxicity.

[Uses]

Alkylating agent with antileukemic activity. Antineoplastic
[Uses]

Antineoplastic alkylating agent, the palliative treatment of chronic myeloid leukemia, and insect sterilant.
[Uses]

Busulfan USP (Myleran) is used to treat Chronic granulocytic leukemia; other myeloproliferative disorders.
[Definition]

ChEBI: A methanesulfonate ester that is butane-1,4-diol in which the hydrogens of the hydroxy groups are replaced by methanesulfonyl groups. An alkylating antineoplastic agent, it is used for the treatment of chronic myeloid leukemia (although it has been largely replaced by newer drugs). It is also used as an insect sterilant.
[Indications]

Busulfan (Myleran) is a bifunctional methanesulfonic ester that forms intrastrand cross-linkages with DNA. The drug is well absorbed after oral administration and has a plasma half-life of less than 5 minutes. Metabolites and degradation products are excreted primarily in the urine.
Busulfan is used in the palliative treatment of chronic granulocytic leukemia. Daily oral therapy results in decreased peripheral white blood cells and improved symptoms in almost all patients during the chronic phase of the disease. Excessive uric acid production from rapid tumor cell lysis should be prevented by coadministration of allopurinol.
At usual therapeutic dosages, busulfan is selectively toxic to granulocyte precursors rather than lymphocytes. Thrombocytopenia and anemia and less commonly, nausea, alopecia, mucositis, and sterility also may occur. Unusual side effects of busulfan include gynecomastia, a general increase in skin pigmentation, and interstitial pulmonary fibrosis.
[Manufacturing Process]

3.6 grams of redistilled 1,4-butanediol were dissolved in 10 ml of pyridine and the solution was cooled in ice and water. 9.6 grams of redistilled methanesulfonyl- chloride were added dropwise at such a rate that the temperature did not rise above 20°C. The solution was then allowed to stand at room temperature to; 30 minutes, during which time the temperature rose to 60°C. A thick precipitate of pyridine hydrochloride was formed.
The mass was cooled in ice water and was treated with 30 ml of ice cold water. On agitation, a white crystalline precipitate was formed. This was filtered off and washed well with ice cold water and allowed to drain on the pump. It weighed 7.8 grams and had a melting point of 100°C. 3.5 grams of the material were recrystallized from acetone and ether to give small white needles, having a melting point of 106°-107°C, unchanged by further recrystallization.
[Brand name]

Myleran (GlaxoSmithKline).
[Therapeutic Function]

Antineoplastic
[Clinical Use]

Busulfan is used in the treatment of chronic myelogenous leukemia and can be administered either orally or by IV infusion.
[Side effects]

Serious bone marrow hypoplasia and myelosuppression are possible with this agent, and recovery from busulfaninduced pancytopenia can take up to 2 years.
[Synthesis]

Busulfan, 1,4-butandioldimethansulfonate (30.2.3.1), is made by reacting butandiol with methanesulfonyl chloride.

[Potential Exposure]

Those involved in the manufacture,formulation, or use of this compound which finds application as an insect sterilant, and as a chemotherapeutic agenttaken orally to treat some kinds of leukemia.
[Veterinary Drugs and Treatments]

Busulfan may be useful in the adjunctive therapy of chronic granulocytic leukemias or polycythemia vera in small animals. Not commonly used in veterinary medicine.
[Drug interactions]

Potentially hazardous interactions with other drugs
Antibacterials: concentration increased by metronidazole.
Antipsychotics: avoid with clozapine, increased risk of agranulocytosis.
Antifungals: metabolism inhibited by itraconazole, monitor for signs of busulfan toxicity.
[First aid]

If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately with wateror normal saline for 20 30 min, occasionally lifting upperand lower lids. Seek medical attention immediately. If thischemical contacts the skin, remove contaminated clothingand wash immediately with soap and water. Seek medicalattention immediately. If this chemical has been inhaled,remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped.Transfer promptly to a medical facility. When this chemicalhas been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit.
[Carcinogenicity]

1,4-Butanediol dimethanesulfonate is known to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in humans.
[Metabolism]

Busulfan is extensively metabolised in the liver, mainly by conjugation with glutathione, either spontaneously or mediated by the enzyme glutathione-S-transferase. About 12 inactive metabolites have been identified, which are excreted in the urine. About 1% of busulfan is excreted unchanged. Elimination in the faeces is considered to be negligible.
[storage]

Store at -20°C
