产品描述 Staurosporine (AM-2282) is a protein kinase inhibitor with ATP-competitive and non-selective inhibitory activity (IC50=6/15/2/3/3000 nM) against PKC, PKA, c-Fgr, phosphorylase kinase and TAOK2. Staurosporine also induces apoptosis.
靶点活性 PKCε:73 nM, PKCζ:1086 nM, PKCγ:5 nM, PKCδ:20 nM, PKCη:4 nM, PKCα:2 nM
体外活性 方法:人宫颈癌细胞 HeLa 用 Staurosporine (1-10 nM) 处理 72 h,使用 MTT 方法检测细胞活力。
结果:Staurosporine 对 Hela 细胞增殖具有剂量依赖性抑制作用,IC50 约为 10 nM。[1]
方法:人胰腺癌细胞 PaTu 8988t、Panc-1 用 Staurosporine (1 μM) 处理 3-24 h,使用 Flow Cytometry 方法检测细胞死亡情况。
结果:PaTu 8988t 细胞,Staurosporine 孵育 3-24 h 显著增加了细胞凋亡率,并显著减少了生命细胞的数量;培养 6-16 h 后,坏死率增加。Panc-1 细胞,Staurosporine 处理在 9-24 h 后显著增加细胞凋亡并显著减少生命细胞的数量。[2]
方法:人肝癌细胞 HepG2 用 Staurosporine (20  nmol/L) 处理 6-24 h,使用 Western Blot 方法检测靶点蛋白表达水平。
结果:Staurosporine 显著抑制 mTOR 磷酸化并增加自噬标记蛋白 LC3-II 的表达,表明 Staurosporine 通过抑制 mTOR 有效激活自噬。[3]
体内活性 方法:为检测体内抗肿瘤活性,将 Staurosporine (3 mg/kg) 和 Lapatinib (50 mg/kg) 灌胃给药给携带人乳腺癌肿瘤 JIMT-1 的 Nu/J-Foxn1 Nu/Nu 小鼠,每周两次,持续两周。
结果:Staurosporine 和 Lapatinib 的组合以统计学显著的方式抑制了肿瘤生长。[4]
方法:为检测对胰岛 β 细胞功能的影响,将 Staurosporine (0.4 mg/kg in 0.5% sodium carboxymethyl cellulose) 腹腔注射给 iPLA2β-/-的 C57BL6 小鼠,每天一次,持续两周。
结果:Staurosporine 会损害动物的糖耐量和胰岛的葡萄糖刺激的胰岛素分泌。[5]
激酶实验 Enzyme assay and binding assay: Protein kinase C is assayed in a reaction mixture (0.25 mL) containing 5 μmol of Tris/HCl, pH 7.5, 2.5 μmol of magnesium acetate, 50 μg of histone II S, 20 μg of phosphatidylserine, 0.88 μg of diolein, 125 nmol of CaCl2, 1.25 nmol of [γ-32]ATP (5-10 × 104 cpm/nmol) and 5 μg of partially purified enzyme. The binding of [3H]PDBu to protein kinase C is determined: Reaction mixture (200 μL contained 4 μmo1 of Tris/malate, pH 6.8, 20 μmol of KCl, 30 nmol of CaC12, 20 μg of phosphatidylserine, 5 μg of partially purified protein kinase C, 0.5% (final concentration) of DMSO,10 pmol of [3H]PDBu (l-3 × 104 cpm/pmol) and 10 μL of various amounts of Staurosporine.
细胞实验 Cells are exposed to Staurosporine for ~32 hours. Cells are fixed in 4% paraformaldehyde and stained with the DNA-binding dye Hoechst 33342. Cells are visualized under epifluorescence illumination, and the percentage of apoptotic cells (cells with condensed and fragmented DNA) is determined. (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。
