英文名: Decitabine；5-Aza-2'-deoxycytidine
中文名: 地西他滨,5-氮杂-2'-脱氧胞嘧啶核
用途:地西他滨作为特异的 DNA甲基化转移酶抑制剂 ,可逆转 DNA的甲基化过程，诱导肿瘤细胞向正常细胞分化或诱导肿瘤细胞凋亡。在肿瘤细胞内，地西他滨被脱氧胞苷激酶磷酸化，以磷酸盐的形式与 DNA掺合。高浓度的地西他滨掺合可抑制 DNA合成诱导细胞死亡，发挥其细胞毒作用;低浓度的地西他滨掺合可替代肿瘤细胞内的胞嘧啶与 DNA甲基化转移酶共价结合，使 DNA甲基化转移酶失活但不会导致细胞死亡。

General description Decitabine is an epigenetic modifier that inhibits DNA methyltransferase activity which results in DNA demethylation (hypomethylation) and gene activation by remodeling “opening” chromatin. Genes are synergistically reactivated when demethylation is combined with histone hyperacetylation.
