Azacitidine is also known as Vidaza, 5-azacytidine, Mylosar, and Ladakamycin. Azacitidine and its deoxy derivative, decitabine (5-aza-2'deoxycytidine), are used in the treatment of myelodysplastic syndrome. The azacytidine in the DNA forms a stable complex with DNA methyltransferase enzymes, preventing DNMT activity and resulting in hypomethylation of cellular DNA. Likewise, the incorporation of azacytidine into RNA leads to the dissembly of polyribosomes, defective methylation and inhibition of protein production with subsequent cytotoxicity.
Soluble in DMSO. Insoluble in acetone, ethanol, and methyl ethyl ketone. Slightly soluble in
ethanol/water combination of fifty-fifty, and propylene glycol.
Biological Activity
When testing anti-tumor effects in prostate cancer the antiproliferative effect of azacitidine treatment in 22rv1 cells and PC3 cells, the IC50’s were 0.5 µM and 2.5 µM respectively.
