Biological Activity I Assay Protocols (From Reference)
Targets
DNMT1
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.

  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
