ln Vitro |
5-Aza-4'-thio-2'-deoxycytidine (5-Aza-T-dCyd; 72 h) inhibits leukemia lines: CCRF-CEM (IC50=0.2 μM), KG1a (IC50=0.06 μM). 5-Aza -4'-thio-2'-deoxycytidine also decreases viability in the NCI-H23 lung carcinoma (IC50=4.5 μM), HCT-116 colon carcinoma (IC50=58 μM) and IGROV-1 ovarian carcinoma (IC50=36 μM) [1]. 5-Aza-4'-thio-2'-deoxycytidine (0.1-20 μM; 96 h) markedly depletes DNMT1 in NCI-H23 lung, HCT-116 colon and IGROV-1 ovarian cells. 5-Aza-4'-thio-2'-deoxycytidine (0.1, 0.5, 1 μM; 96 h) results in marked depletion of DNMT1 in CCRF-CEM and KG1a myeloid leukemia cells[1]. 5-Aza-4'- thio-2'-deoxycytidine (1 μM; 96 h) induces CpG demethylation and re-expression of the p15 tumor suppressor gene[1].

ln Vivo |
5-Aza-4'-thio-2'-deoxycytidine (6.7, 10 mg/kg/day; IP; for 9 days) is effective against NCI-H23 tumor xenografts[1]. 5-Aza-4'-thio- 2'-deoxycytidine (5 mg/kg/day; IP; for 9 days) decreases DNMT1 levels in tumors of CCRF-CEM tumors mice xenografts[1]. 5-Aza-4'-thio-2'-deoxycytidine (1.5 mg /kg; ip; QD×5 rest and repeat 3 cycles) provides modest suppression of tumor growth as well in the HCT116 colon carcinoma, OVCAR3 ovarian tumor xenograft model. 5-Aza-4'-thio-2'-deoxycytidine has minimal antitumor effect in the HL-60 leukemia xenografts[2].

Additional Infomation |
5-Aza-4'-thio-2'-deoxycytidine is an orally bioavailable, nucleoside analog and DNA methyltransferase I (DNMT1) inhibitor, with potential DNA hypomethylating and antineoplastic activities. Upon administration, 5-aza-4'-thio-2'-deoxycytidine (Aza-TdC) gets incorporated into DNA, where it binds to the active site of DNMT1, a maintenance methyltransferase that contributes to the hypermethylation and silencing of tumor suppressor genes. The formation of covalent DNMT1-DNA complexes inhibits DNMT1, prevents DNA methylation of CpG sites, causes CpG demethylation, and results in the re-expression and re-activation of silenced tumor suppressor genes. This inhibits tumor cell proliferation. DNMT1, overactivated in tumor cells, plays a key role in tumor cell proliferation.

Solubility (In Vivo) |
Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80: Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 :Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

Injection Formulation 4: DMSO : 20% SBE-β-CD in saline = 10 : 90 [i.e. 100 μL DMSO → 900 μL (20% SBE-β-CD in saline)] Oral Formulations
Oral Formulation 1: Suspend in 0.5% CMC Na (carboxymethylcellulose sodium) Oral Formulation 2: Suspend in 0.5% Carboxymethyl cellulose Example: Take the Oral Formulation 1 (Suspend in 0.5% CMC Na) as an example, if 100 mL of 2.5 mg/mL working solution is to be prepared, you can first prepare 0.5% CMC Na solution by measuring 0.5 g CMC Na and dissolve it in 100 mL ddH2O to obtain a clear solution; then add 250 mg of the product to 100 mL 0.5% CMC Na solution, to make the suspension solution (2.5 mg/mL, ready for use in animals).

Preparing Stock Solutions | 1 mg | 5 mg | 10 mg | |
1 mM | 4.0938 mL | 20.4692 mL | 40.9383 mL | |
5 mM | 0.8188 mL | 4.0938 mL | 8.1877 mL | |
10 mM | 0.4094 mL | 2.0469 mL | 4.0938 mL |
*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.
