Azacitidine (Ladakamycin; 5-AzaC):Nature. 2021 Aug 25. doi: 10.1038/s41586-021-03850-3.
Purity: ≥98%
5-Azacytidine (5AzaC; Ladakamycin; U-18496; Vidaza; Mylosar; 5-AzaC) is an FDA approved anticancer drug bearing a pyrimidine nucleoside core and belongs to cytosine class of antimetabolites. It acts as a DNA methyl transferase (DNMT) inhibitor.
ln Vitro |
Unmethylated CpG islands associated with a number of genes are partially or fully methylated in malignancies and can be reactivated by 5-Azacytidine [1]. 5-Azacytidine works as a mild inducer of erythroid differentiation of Friend erythroleukemia cells within the same dose range that influences DNA methyltransferase activity [2]. 5-Azacytidine inhibits L1210 cells with ID50 and ID90 values of 0.019 and ~0.15 μg/mL, respectively [3].

ln Vivo |
TdR-3H incorporation was markedly decreased when rats were treated to 5-Azacytidine (100 mg/kg, i.p.) for two hours or longer [3].

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration: mg/mL;
Method for preparing DMSO stock solution: mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation::Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O,mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
