General description

Chemical structure: nucleoside

Application

5-Azacytidine may be used to induce in vitro cardiomyogenic differentiation of adult human bone marrow mesenchymal stem cells. It may also be used to study the effects of 5-Azacytidine on the immune regulatory myeloid-derived suppressor cells (MDSCs) and regulatory T cells (Tregs).
Used to study the effects of the DNA incorporated molecule on DNA methylation processes.

Biochem/physiol Actions

5-Azacytidine is a deoxycytidine analog and a demethylating agent. It acts as a potential antineoplastic agent for acute myelogenous leukemia. 5-Azacytidine activates repressed genes by inhibiting DNA methylation. 5-Azacytidine also affects protein synthesis by altering the RNA function and stability.
A potent growth inhibitor and cytotoxic agent; inhibits DNA methyltransferase, an important regulatory mechanism of gene expression, gene activation and silencing.

Reconstitution

Reconstitute contents of vial with 10 mL sterile cell culture medium. Stock solution is sufficient to prepare 500ml medium. Final working concentration: 10 μM 5-azacytidine.

5-Aza-2'-deoxycytidine (5-azadC) is a DNA methyltransferase (DNMT) inhibitor increasingly used in treatments of hematological diseases and works by being incorporated into DNA and trapping DNMT. It is unclear what DNA lesions are caused by 5-azadC and if such are substrates
