5-Aza-2'-deoxycytidine Chemical Properties,Uses,Production

Indications and Usage

5-Aza-2’-deoxycytidine, also known as decitabine or 2'-deoxy-5-azacytidine, is a cell cycle S phase-specific drug used to treat myelodysplastic syndromes (MDS.)

Mechanisms of Action

Demethylating agents can regulate gene expression by activating tumor suppressor genes and enhancing the differentiation of genes, which help treat MDS. 5-Aza-2’-deoxycytidine is a natural andenosine analogue of 2′-deoxycytidine, known to the be strongest methylation specific inhibitor of DNA. After phosphorylation it can inhibit DNA methyltransferase, reducing DNA methylation, leading to demethylation of tumor cells, which can restore the normal functioning of genes, thus inhibiting tumor cell proliferation and preventing the occurrence of drug resistance. 5-Aza-2’-deoxycytidine inhibits DNA methylation in vitro, but does not affect its synthesis. Moreover, non-proliferating cells are not sensitive to it. 5-Aza-2’-deoxycytidine has anti-tumor activity and is characterized by a dual mechanism based on dose differences. At high concentrations it is cytoxic, while at low concentrations it is demethlyating.

Decitabine, 5-aza-2’-deoxycytidine, has been launched for the treatment of myelodysplastic syndromes (MDS). MDS are a set of hematologic disorders affecting the bone marrow that result in ineffective formation and development of blood cells. Furthermore, patients with MDS have a high risk of progressing to acute myeloid leukemia (AML). Traditional treatments include blood transfusions, hematopoietic growth factors, and prophylactic antibiotics, but these measures merely improve the quality of life with questionable effects on disease modification. While stem-cell transplantation is an aggressive, potentially curative approach, the advanced age or the other complicating health issues of most patients preclude them from considering this option. Recent advances in the underlying etiology of MDS, however, have led to the development of a new class of compounds known as ‘‘demethylating agents’’. Decitabine follows the successful introduction of the first DNA methyltransferase inhibitor azacitidine.

Chemical Properties

white crystalline powder


Pharmachemie (Netherlands)


Used as cancer treatment, in particular to inhibit the growth of pancreatic endocrine tumor cell lines.


Decitabine is a potent inhibitor of DNA methylation with IC50 of 438 nM and 4.38 nM in HL-60 and KG1a cells, respectively

brand name

Dacogen (Millot Laboratories, France).

General Description

Fine white crystalline powder. Used as a drug.

Air & Water Reactions

Probably light and air sensitive. Water soluble. Decomposes in aqueous solution at a rate that depends on pH: at pH 7 the drug is more stable than at pH 9, but is less stable than at pH 6. At pH 7 and 99°F, approximately 7% conversion occurs in 1 hour .

Reactivity Profile

5-Aza-2'-deoxycytidine is an aminoalcohol. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides.

Fire Hazard

Flash point data for 5-Aza-2'-deoxycytidine are not available. 5-Aza-2'-deoxycytidine is probably combustible.

Biological Activity

Cytosine analog that once incorporated into DNA acts as a suicide substrate for DNA methyltransferase. Inhibits DNA methyltransferase and results in DNA hypomethylation and activation of silent genes. Chemotherapeutic agent; suppresses growth of human tumor cell lines. Demethylates differentiation-related genes; reverses embryonic stem cell differentiation.

Safety Profile

Poison by intravenous route.Human mutation data reported. When heated todecomposition it emits toxic fumes of NOx.

Chemical Synthesis

Silylated 5-aza-cytosine (28) was condensed with 9- fluorenylmethoxycarbonyl (Fmoc) protected 2-deoxy-1-chlororibose (27) with tin chloride (IV) in dichloroethane (Scheme 4). The coupled product 29 was de-protected with excess triethylamine in dry pyridine to give decitabine (IV) in 36% yield after separation from its corresponding αisomer.
