5-Azacytidine (Azacitidine; 5-AzaC; Ladakamycin) 是胞苷核苷類似物,特異型抑制 DNA 甲基化。5-Azacytidine 與 DNA 結(jié)合共價捕獲 DNA甲基轉(zhuǎn)移酶 (DNA methyltransferases),有益于逆轉(zhuǎn)表觀遺傳變化。5-Azacytidine 誘導(dǎo)細(xì)胞自噬 (autophagy)。
生物活性
5-Azacytidine (Azacitidine; 5-AzaC; Ladakamycin) is a nucleoside analogue of cytidine that specifically inhibits DNA methylation. 5-Azacytidine is incorporated into DNA to covalently trap DNA methyltransferases and contributes to reverse epigenetic changes[1][2]. 5-Azacytidine induces cell autophagy[4].
IC50 & Target[1]
DNMT1 Nucleoside Antimetabolite/Analog Autophagy
體外研究(In Vitro)
Unmethylated CpG islands associated with a variety of genes become partially or fully methylated in tumors and can be reactivated by 5-Azacytidine[1]. 5-Azacytidine acts as weak inducers of erythroid differentiation of Friend erythroleukemia cells in the same concentration range where they affect DNA methyltransferase activity[2]. 5-Azacytidine inhibits L1210 cells with ID50 and ID90 values of 0.019 and circa 0.15 μg/mL, respectively[3].
體內(nèi)研究(In Vivo)
TdR-3H incorporation is significantly inhibited when the animals are exposed to 5-Azacitidine (100 mg/kg, i.p.) for 2 hr or longer[3].
