包装规格:25mg 50mg 100mg in glass bottle
产品简介:一种具有辐射防护能力的细胞保护剂。Amifostine thiol 通过 JNK 依赖的信号通路激活 p53。
溶解性:溶于水
储备液保存:-80°C, 6 months -20°C, 1 month (protect from light, stored under nitrogen)
体内实验:1、请依序添加每种溶剂: PBS Solubility: 16.67 mg/mL (124.18 mM); 澄清溶液; 超声助溶 <1mg/ml表示微溶或不溶。 普西唐提供的所有化合物浓度为内部测试所得,实际溶液度可能与公布值有所偏差,属于正常的批间细微差异现象。 请根据产品在不同溶剂中的溶解度选择合适的溶剂配制储备液;一旦配成溶液,请分装保存,避免反复冻融造成的产品失效。
靶点:p53
体外研究:Amifostine thiol can reduce both the direct and delayed detrimental effects of both high and low-LET radiation exposures. Amifostine thiol attenuates both the DNA damage and the G1-phase arrest induced by radiation. Amifostine thiol (4 mM; 30 minutes) protects RKO36 cells from chromosomal damage and death induced by ionizing radiation. Amifostine thiol (4 mM; 30 minutes) protects irradiated RKO36 cells from delayed genomic instability. Amifostine thiol is cytotoxic to RKO36 cells at milimolar concentrations, especially after continuous treatment. Amifostine thiol at 40 μM protects RKO36 cells from delayed genomic instability but not from cell death and immediate chromosomal damage. Amifostine thiol activates JNK resulting in the phosphorylation of p53 at threonine 81. Amifostine thiol affects phosphorylation of topoisomerase IIα leading to changes in enzyme activity and cell cycle progression in CHO AA8 cells.
