N,N-二亚硝基哌嗪性质、用途与生产工艺

生物活性 N,N'-Dinitrosopiperazine (1,4-Dinitrosopiperazine; DNP) 是一种致癌物 (carcinogen)，特异性针对鼻咽癌，可促进鼻咽癌的转移。N,N'-Dinitrosopiperazine 通过蛋白磷酸化调节多种信号通路，包括 LYRIC，在丝氨酸 568 位。

体外研究

N,N'-Dinitrosopiperazine (0.5-100 μM; 48 hours) has no inhibitory effects on the labeled 6-10B cells, and LDH activity is not significantly altered by DNP treatment in the 0.5-8 μM concentration range. However, it is cytotoxic from the concentration 10 μM.N,N'-Dinitrosopiperazine (2-8 μM; 24 hours) induces 6-10B cell invasion and motility in a dose-dependent manner. At 6 μM, when compares to the control group, DNP increases cell invasion at 421.7% and cell motility is increased by 328.2%.N,N'-Dinitrosopiperazine (6 μM; 24 hours) increases the expression of phospho-LYRIC s568 and LYRIC expression in CNE1 cells.

Cell Viability Assay

Cell Line:	The labeled 6-10B cells
Concentration:	0.5, 1, 2, 4, 6, 8, 10, 20, 40, 80, or 100 μM
Incubation Time:	48 hours
Result:	Had no inhibitory effects at the concentration 0-8 μM.

Western Blot Analysis

Cell Line:	The NPC cell line CNE1
Concentration:	6 μM
Incubation Time:	24 hours
Result:	Increased phospho-LYRIC s568 and LYRIC expression.

体内研究

N,N'-Dinitrosopiperazine (injected into the tail veins; 40 mg/kg; 30 days) inhibits cell motility and invasion, and facilitates NPC metastasis in vivo. From a IHC result, Phospho-LYRIC expression is higher in the metastatic tumors of DNP-treated mice than in those of the untreated control mice.

Animal Model:	BABL/c nude mice injected with labeled 6-10B cell suspensions (1 × 10 ⁴ cells) with or without DNP(40 mg/kg)
Dosage:	40 mg/kg
Administration:	Injected into the tail veins; 30 days
Result:	Induced LYRIC phosphorylation at serine 568 associated with NPC metastasis in vivo.
