| Description | 5-Azacytidine is an inhibitor of DNA methyltransferase. | |||||
| Targets | DNA methyltransferase | |||||
| IC50 | ||||||
| Cell experiment [1]: | |
Cell lines | Leukemia L1210 cells |
Preparation method | The solubility of this compound in DMSO is > 12.2 mg/mL. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below - 20 °C for several months. |
Reacting condition | 80 μM; 0 ~ 120 mins |
Applications | In leukemia L1210 cells, 5-Azacytidine showed greater inhibition on DNA synthesis instead of RNA synthesis. After a 90-min preincubation, TdR-3H incorporation was inhibited by about 74%, whilst UR-3H incorporation was inhibited by only 32%. |
| Animal experiment [2]: | |
Animal models | BDF1 mice bearing lymphoid leukemia L1210 cells |
Dosage form | 3 mg/kg; i.p.; q.d. |
Applications | In BDF1 mice bearing lymphoid leukemia L1210 cells, 5-Azacytidine increased the mean survival time. Moreover, 5-Azacytidine significantly suppressed all enzymes activity in the polyamine-biosynthetic pathway. In addition, 5-Azacytidine inhibited accumulation of polyamines in leukemic mice. |
Other notes | Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |

5-Azacytidine (also known as 5-AzaC), a compound belonging to a class of cytosine analogues, is a DNA methyl transferase (DNMT) inhibitor that exerts potent cytotoxicity against multiple myeloma (MM) cells, including MM.1S, MM.1R, RPMI-8266, RPMI-LR5, RPMI-Dox40 and Patient-derived MM, with the half maximal inhibition concentration IC50 values of 1.5 μmol/L, 0.7 μmol/L, 1.1 μmol/L, 2.5 μmol/L, 3.2 μmol/L and 1.5 μmol/L respectively [1].
5-Azacytidine incorporates into cellular DNA and/or RNA, subsequently sequesters DNMT and forms a covalent bond between C6 of 5-Azacytidine and cysteine thiolate of DNMTs resulting in depletion of DNMT activity in cells and demethylation of cellular DNA [1].

1.若都为正常，那么并未有太大问题，只要定期复查就可以了。
2.如果TGAb、TMAb、甲状腺功能均高，那么就是桥本氏甲状腺炎并甲亢，需要抗甲亢治疗。
3.如果TGAb、TMAb高，甲状腺功能下降，那么就是桥本氏甲状腺炎并甲减，需要进行甲减治疗。
4.如果TGAb、TMAb高，甲状腺功能正常，那么就是桥本氏甲状腺炎，无需特殊治疗，只要定期复查甲状腺功能就可能以了，不过这种情况有可能以后演变成甲减或者甲亢。
