Data Sheet 产品使用指南

Decitabine (5-Aza-2'-deoxycytidine) 是一种具有口服活性的脱氧胞苷类似物抗代谢物 (deoxycytidine analogue antimetabolite) 和 DNA 甲基转移酶 (DNA methyltransferase) 抑制剂。Decitabine 代替 DNA 掺入胞嘧啶可以将 DNA 甲基转移酶共价捕获到 DNA 中，从而导致对该酶的不可逆抑制。Decitabine 诱导细胞 G2/M 阻滞和细胞凋亡 (apoptosis)，并具有有效的抗癌活性。

生物活性

Decitabine (NSC 127716) is an orally active deoxycytidine analogue antimetabolite and a DNA methyltransferase inhibitor. Decitabine incorporates into DNA in place of cytosine can covalently trap DNA methyltransferase to DNA causing irreversible inhibition of the enzyme. Decitabine induces cell G2/M arrest and cell apoptosis. Decitabine has potent anticancer activity.

体外研究

Decitabine treatment significantly inhibits cell growth of SNU719, NCC24 and KATOIII 96 hours after exposure to decitabine. Decitabine induces G2/M arrest and apoptosis in EBVaGC, inhibits invasion ability, and up-regulates E-cadherin expression for EBVaGC.
Only high concentrations (10 µM) Decitabine (0.1-1 μM; 24-72 hours) results in a G2 phase arrest, which is accompanied by a reduction of cells in G1 phase.
Decitabine up-regulates DCTPP1 and dUTPase expression in HeLa cells.

Cell Cycle Analysis

Cell Line:	HCT116 cells
Concentration:	0.1, 1, 10 µM
Incubation Time:	24, 48, 72 hours
Result:	Only high drug concentrations (10 µM) resulted in a G2 phase arrest, which was accompanied by a reduction of cells in G1 phase.

体内研究

Decitabine (1.0 mg/kg, p.o.) in combination with tetrahydrouridine (THU) causes severe toxicity occurs in female CD-1 mice, and results in an increased sensitivity to decitabine toxicity correlating with decitabine plasma levels.
Decitabine (1.0 mg/kg; i.p.; once daily for 5 consecutive days) leads to regression of EL4 tumors established in C57BL/6 Mice.

Animal Model:	C57BL/6 mice (bearing EL4 cells)
Dosage:	1.0 mg/kg
Administration:	Intraperitoneal injection; once daily for 5 consecutive days
Result:	Caused continuous tumor regression even after Decitabine treatment was stopped.
