Application

5-Aza-2′-deoxycytidine has been used as a demethylating agent in breast cancer cell line, chromatin, DNA and promoter region of p16 gene.

Biochem/physiol Actions

5′-Azadeoxycytidine causes DNA demethylation or hemi-demethylation. DNA demethylation can regulate gene expression by "opening" the chromatin structure detectable as increased nuclease sensitivity. This remodeling of chromatin structure allows transcription factors to bind to the promoter regions, assembly of the transcription complex, and gene expression. Decitabine is an epigenetic modifier that inhibits DNA methyltransferase activity which results in DNA demethylation (hypomethylation) and gene activation by remodeling "opening" chromatin. Genes are synergistically reactivated when demethylation is combined with histone hyperacetylation.

General description

5-Aza-2′-deoxycytidine is a DNA-hypomethylating agent, which stimulates differentiation and apoptosis of leukemic cells. It is a 2′-deoxycytidine analogue. 5-Aza-2′-deoxycytidine is used to treat chronic myelomonocytic leukemia, refractory anemia, myelodysplastic syndrome and acute myeloid leukemia.
5-Aza-2′-deoxycytidine, also known as Decitabine, is a DNA-hypomethylating agent that promotes differentiation and apoptosis in leukemic cells. It is a 2′-deoxycytidine analog that causes DNA demethylation or hemi-demethylation, which can regulate gene expression by "opening" the chromatin structure, making it more sensitive to nucleases. This chromatin remodeling allows transcription factors to bind to promoter regions, facilitating the assembly of the transcription complex and subsequent gene expression. As an epigenetic modifier, Decitabine inhibits DNA methyltransferase activity, leading to DNA hypomethylation and gene activation. The reactivation of genes is further enhanced when demethylation is combined with histone hyperacetylation. Decitabine is used to treat chronic myelomonocytic leukemia, refractory anemia, myelodysplastic syndrome, and acute myeloid leukemia.

  3. How should Product A3656, 5-Aza-2´-deoxycytidine, be dissolved?

    This product is typically dissolved at 50 mg/ml in 50% acetic acid to yield a clear colorless solution. This product is also soluble at 50 mg/ml in DMSO or 0.25 mg/ml in water.

  4. What is the solution stability of Product A3656, 5-Aza-2´-deoxycytidine? 

    Aqueous solutions of this product appear to be very unstable, probably by analogy to A2385, aza-cytidine. We suggest preparing solution fresh for each use and storing solutions on ice until use within a few hours.  

  5. What is the difference between 5-Aza-2´-deoxycytidine Products A3656 and A1287?

    Both of these products inhibit DNA methyltransferase.  However, they are different chemicals.  Product No. A3656 is 5-Aza-2´-deoxycytidine and A1287 is 5-Azacytidine. Product No. A1287 is γ-irradiated, hybridoma- and endotoxin-tested, and Product No. A3656 is not.
