하이드록시우레아 MSDS


Hydroxyurea

하이드록시우레아 C화학적 특성, 용도, 생산

화학적 성질

Off-White Crystalline Solid

용도

An anti-neoplastic - inhibits ribonucleoside reductase and DNA replication. A potential therapy for sickle cell anemia which involves the nitrosylation of sickle cell hemoglobin. Horseradish peroxidase catalyzes nitric oxide formation from hydroxyurea in the presence of hydrogen peroxide.

용도

antineoplastic, inhibits ribonucleoside diphosphate reductase

Indications

Hydroxyurea (Hydrea) inhibits the enzyme ribonucleotide reductase and thus depletes intracellular pools of deoxyribonucleotides, resulting in a specific impairment of DNA synthesis. The drug therefore is an Sphase specific agent whose action results in an accumulation of cells in the late G1- and early S-phases of the cell cycle.

일반 설명

Odorless or almost odorless white to off-white crystalline solid. Tasteless.

일반 설명

HONH-CO-NH2. The drug is available in a 500-mg capsulefor oral use. Hydroxyurea is often considered an antimetabolitedrug, and it is used to treat myelogenousleukemia, ovarian cancer, and essential thrombocytosis. Themechanism of action of hydroxyurea involves inhibition ofDNA biosynthesis by inhibition of the enzyme ribonucleotidereductase). Resistance can occur viaincreased expression of ribonucleotide reductase. The oralbioavailability is quite high approaching 100% and the drugis distributed to all tissues. Hydroxyurea readily enters theCNS and distributes to human breast milk. A major portionof the total dose is excreted unchanged in the urine. Thedrug has been shown to increase the toxicity of 5-FU, andhydroxyurea may increase the effectiveness of some antimetaboliteHIV drugs. The toxicity profile includes myelosuppression,leucopenia, nausea, vomiting, pruritus hyperpigmentation,headache, drowsiness, and confusion.

공기와 물의 반응

Water soluble.

반응 프로필

An amide. Amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases (weaker than water). Mixing amides with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx).

화재위험

Flash point data for Hydroxyurea are not available; however, Hydroxyurea is probably combustible.

Mechanism of action

Hydroxyurea is rapidly absorbed after oral administration, with peak plasma levels achieved approximately 1 to 2 hours after drug administration; its elimination half-life is 2 to 3 hours. The primary route of excretion is renal, with 30 to 40% of a dose excreted unchanged.

Clinical Use

Hydroxyurea is used for the rapid lowering of blood granulocyte counts in patients with chronic granulocytic leukemia. The drug also can be used as maintenance therapy for patients with the disease who have become resistant to busulfan. Only a small percentage of patients with other malignancies have had even brief remissions induced by hydroxyurea administration.

부작용

Hematological toxicity, with white blood cells affected more than platelets, may occur. Megaloblastosis of the bone marrow also may be observed. Recovery is rapid, generally within 10 to 14 days after discontinuation of the drug. Some skin reactions, including hyperpigmentation and hyperkeratosis, have been reported with chronic treatment.

Veterinary Drugs and Treatments

Hydroxyurea may be useful in the treatment of polycythemia vera, mastocytomas, and leukemias in dogs and cats. It is often used to treat dogs with chronic myelogenous leukemia no longer responsive to busulfan. Hydroxyurea, potentially, may be of benefit in the treatment of feline hypereosinophilic syndrome and in the adjunctive treatment of canine meningiomas. It can also be used in dogs for the adjunctive medical treatment (to reduce hematocrit) of right to left shunting patent ductus arteriosis or tetralogy of Fallot.

Purification Methods

Recrystallise hydroxyurea from absolute EtOH (10g in 150mL). Note that the rate of solution in boiling EtOH is slow (15-30minutes). It should be stored in a cool dry place, but some decomposition could occur after several weeks. [Deghenghi Org Synth Coll Vol V 645 1973.] It is very soluble in H2O and can be crystallised from Et2O. [Kfod Acta Chem Scand 10 256 1956, Beilstein 3 IV 170.]
