产品描述 | Fludarabine Phosphate (NSC 312887 Phosphate) is the phosphate salt of a fluorinated nucleotide antimetabolite analog of the antiviral agent vidarabine (ara-A) with antineoplastic activity. Fludarabine phosphate is rapidly dephosphorylated to 2-fluoro-ara-A and then phosphorylated intracellularly by deoxycytidine kinase to the active triphosphate, 2-fluoro-ara-ATP. This metabolite may inhibit DNA polymerase alpha, ribonucleotide reductase, and DNA primase, thereby interrupting DNA synthesis and inhibiting tumor cell growth. |
靶点活性 | DNA polymerase α:1.1 μM(Ki ), DNA polymerase δ:1.3 μM(Ki) |
体外活性 | Fludarabine Phosphate的最大耐受剂量为234 mg/kg.Fludarabine对小鼠的LD50为375 mg/kg.Fludarabine Phosphate对于无肿瘤的小鼠有毒性.在携带P388白血病的小鼠中,Fludarabine Phosphate可诱导细胞存活治疗的数量减少,寿命更大比例地增加110%,平均存活时间增加. |
体内活性 | Fludarabine Phosphate完全抑制DNA聚合酶α/δ(Ki:1.1/1.3 μM)。在体外,DNA聚合酶δ可将Fludarabine Phosphate从结合的DNA上切除。Fludarabine Phosphate与三磷酸脱氧腺苷竞争性地结合到延伸DNA链的A位点,使DNA链延伸的终止人DNA聚合酶α比δ更能将Fludarabine Phosphate结合到DNA中。 |
细胞实验 | Cells are incubated with Fludarabine Phosphate for 5 hr and washed twice with drug-free warm medium. 800 cells are mixed with 1.3 mL of 0.25% soft agar in Dulbecco's medium supplemented with 20% fetal bovine serum (pre-warmed to 37 ℃) and incubated in a tissue culture dish for 10 days (humidified 5% CO2 , 37 ℃). At the end of the incubation period, colonies of more than 40 cells are scored under a microscope. The cytotoxic effect of the drugs is expressed as a percentage of survival relative to that of untreated control cells.(Only for Reference) |

请在以下方框中输入您的动物实验信息后点击计算,可以得到母液配置方法和体内配方的制备方法: 比如您的给药剂量是10 mg/kg,每只动物体重20 g,给药体积100 μL,一共给药动物10 只,您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。
母液配置方法:2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL), 如您需要配置的浓度超过该产品的溶解度,请先与我们联系。
体内配方的制备方法:取 50 μL DMSO 主液,加入 300 μL PEG300, 混匀澄清,再加 50 μL Tween 80,混匀澄清,再加 600 μL ddH2O, 混匀澄清。
