5-Azacytidine Chemical Properties,Uses,Production


Azacytidine also referred to as Azacytidine and 5-azacytidine (brand name: Vidaza) is an anti-cancer chemotherapy medication. The drug is classified as demethylation and antimetabolite agent. Azacytidine acts by inhibiting the growth and proliferation of cancer cells in the body. The drug is indicated for the treatment of specific types of blood cell disorders and bone marrow cancers.


Azacytidine is prescribed for treating patients with secondary types of myelodysplastic syndrome, including refractory anemia that presents in the form of ringed sideroblasts (especially if it necessitates transfusion), or it presents itself alongside thrombocytopenia or neutropenia. Also, it is used in treating refractory anemia accompanied by excess blasts, refractory anemia characterized by excess blasts in transition (currently classified as chronic myelogenous leukemia that is accompanied by multilineage dysplasia), and acute myelomonocytic leukemia.


Azacytidine is contraindicated in patients who have acute malignant hepatic tumors or known hypersensitivity to the drug or mannitol.


For treatment of patients with myelodysplastic syndrome, the initial dose is 75mg/m2 administered intravenously or subcutaneously in daily doses for 7 days in 4-week intervals. The recommended maintenance dose may be increased to 100mg/m2 if there are no noteworthy effects after 2 treatment cycles and if the patient does not experience additional toxicity other than vomiting and nausea.
Patients should undergo treatment that lasts for a minimum of 4 cycles. However, a partial or complete response may necessitate additional cycles other than the recommended 4 cycles. Treatment should not be discontinued if the patient is experiencing positive outcomes from the therapy.

Mechanism of Action

5-Azacytidine is a chemical analog that is closely linked with the cytosine nucleoside in ribonucleic acid (RNA) and deoxyribonucleic acid (DNA). Azacytidine influences antineoplastic activity through two main mechanisms; suppression of DNA methyltransferase when administered in low doses, which results in hypomethylation of DNA, and unmediated cytotoxicity in anomalous hematopoietic cells present in the bone marrow by its integration into RNA and DNA at high doses which causes the death of the cells.
Since Azacytidine is considered a ribonucleoside, it integrates itself into RNA to a greater extent than DNA. The integration into RNA results in the dissimulation of malfunctioning methylation, polyribosomes, and recipient function of replicated RNA, and suppression of protein production.
The integration of Azacytidine into DNA results in a covalent bond that is characterized by DNA methyltransferases, which inhibits DNA synthesis and resultant cytotoxicity.


Intravenous administration of the radioactive form of the drug to cancer patients results in 85% elimination of Azacytidine through urinary excretion. Fecal excretion of the radioactive dose takes place in <1% of the administered drug in 3 days. The mean elimination of radioactivity through urine accounts for 50% of 14C-azacytidine administration.

Adverse reactions

Common side effects associated with Azacytidine in more than 30% of the patients include low white blood cell count, fever, vomiting, low platelet count, anemia, and nausea. At nadir, 10-17days of chemotherapy cycles, one may also experience petechiae, ecchymosis, constipation, redness at the injection site and fatigue.
Other side effects associated with Azacytidine in about 10-29% of the patients may include insomnia, depression, itching, upper respiratory infection, hypokalemia, anxiety, skin rash, abdominal pain, weight loss, nosebleed, chest pain, swelling on the ankles, dizziness, confusion, back pain, sore throat, poor appetite, headache, myalgia and arthralgia, pain at the injection site, chills, weakness, shortness of breath and coughs.
It is important to contact health care provider if one is experiencing diarrhea (4-6 episodes in 24 hours). A patient should also contact the doctor in case he/she has nausea that interferes with their ability to eat. If one has bloodstained urine, constipation that persists regardless of laxative use, extreme fatigue, tarry or bloodstained stools, vomiting (4-5 episodes in a span of 24 hours), signs of infection such as productive coughs or painful urination, and inability to eat or take fluids for more than 24 hours.


A patient should notify their healthcare provider if they are taking any other medications which may include herbal remedies, vitamins, and over-the-counter medications before receiving an Azacytidine prescription. A patient should not receive any vaccination or immunization while they are on Azacytidine treatment.
Breastfeeding is not recommended while one is taking this drug. A patient should also inform their healthcare provider if they are pregnant or intending to get pregnant before starting Azacytidine treatment.
Azacytidine may cause neutropenia, anemia, and thrombocytopenia. Since the drug may result in hepatotoxicity amongst patients with acute hepatic impairment, caution should be taken during the administration of Azacytidine in patients with liver disease.
Renal toxicity that may range from renal failure to increased serum creatinine and death has been reported amongst patients who have been accorded intravenous treatment with Azacytidine in combination treatment with other chemotherapeutic medications for nonMDS cases.
The drug may also result in acute tumor lysis syndrome for patients with MDS. Azacytidine poses a threat to a developing embryo/fetus based on its mechanism of action.
