Biological Activity |
Cytarabine (AraC)盐酸盐具有抗代谢和抗DNA合成活性。[1-4] |
In Vitro |
Cytarabine明显诱导大鼠交感神经元凋亡10μM,其中100μM显示最高毒性,并在84小时内杀死超过80%的神经元,包括线粒体细胞色素c的释放和caspase-3的激活,以及通过p53敲低可以减弱毒性,并通过bax缺失延迟[2]。Cytarabine被磷酸化为三磷酸盐形式(Ara-CTP),涉及脱氧胞苷激酶(dCK),其与dCTP竞争结合到DNA中,然后通过抑制DNA和RNA聚合酶的功能阻断DNA合成。与其他急性髓性白血病(AML)细胞相比,Cytarabine对野生型CCRF-CEM细胞显示出更高的生长抑制活性,IC50为16 nM [1]。 |
In Vivo |
Cytarabine(250 mg/kg)也会导致胎盘生长迟缓,并增加胎盘迷路细胞凋亡,在孕期Slc:Wistar大鼠的胎盘迷路区,从治疗后3小时开始增加,并在恢复到对照水平前6小时达到峰值。 48小时,p53蛋白显著增强,p53转录靶基因如p21,cyclinG1和fas和caspase-3活性[3]。Cytarabine对急性白血病非常有效,导致Cytarabine的G1/S阻滞和同步化,并以弱剂量相关的方式增加白血病布朗挪威大鼠的存活时间,表明使用更高剂量的Cytarabine无助于它对人体的抗白血病作用[4]。 |
Animal Experiment |
怀孕大鼠在妊娠第13天(GD13)腹膜内(ip)注射250mg/kgCytarabine。在本实验条件下,围产儿胎儿先天畸形和生长迟缓检出率较高,但胎儿死亡率并未明显增加。在处理后1,3,6,9,12,24和48小时,在乙醚麻醉下通过心脏穿刺杀死6个水坝,并收集胎盘。作为对照,在GD13上腹膜内注射6只怀孕的大鼠,并在与Cytarabine处理组相同的时间点处死。 |
Kinase Experiment |
在无水乙醇中制备Cytarabine的储备溶液,并制备Cytarabine的连续稀释液。将CCRF-CEM细胞悬浮于补充有10%FBS,0.1%庆大霉素和1%丙酮酸钠的RPMI培养基中。将细胞悬浮在它们各自的培养基中,得到10mL体积的细胞悬浮液,最终密度为3-6×10 4个细胞/ mL。将适量的Cytarabine溶液转移至细胞悬浮液中,并继续培养72小时。将细胞离心并重新悬浮于不含Cytarabine的新培养基中,并测定最终细胞计数。通过细胞计数与Cytarabine浓度的S形曲线拟合分析数据,结果表示为IC 50(抑制细胞生长的Cytarabine浓度至对照值的50%)。 |
