产品描述 | VER-82576 (NVP-BEP800), a synthetic HSP90β inhibitor (IC50: 58 nM), exhibits >70-fold selectivity against Hsp90 family members Trap-1 and Grp94. |
靶点活性 | HSP90 β:58 nM |
体外活性 | 在A375恶性黑色素移植瘤模型中,NVP-BEP800(15或 30 mg/kg/day,p.o.)处理15天,可剂量依赖性降低B-Raf和Akt磷酸化水平,且有抗癌活性,NVP-BEP800(15和30 mg/kg/day)处理,T/C值分别为53%和6%,每天30 mg/kg则几乎抑制全部肿瘤.在BT-474乳腺癌移植瘤中,NVP-BEP800处理可提高Hsp90-p23复合体解离,并降低稳定态ErbB2,p-Akt和p-S6水平,,该作用呈剂量依赖性,NVP-BEP800(30 mg/kg/day)处理可使肿瘤衰退38%.每天15 mg/kg处理则T/C为36%. |
体内活性 | NVP-BEP800有效抑制包括A375细胞(GI50:38 nM)和PC3细胞(GI50:1.05 μM)在内的多种肿瘤细胞系增殖。在A2058和A549细胞中,NVP-BEP800(GI50的5倍)可提高G2-M期百分数。在BT-474细胞中,NVP-BEP800可浓度依赖性地引起Akt和ErbB2去磷酸化、ErbB2降解和Hsp70诱发(IC50:218/39.5/137/207 nM)。Hsp70浓度为10 μM时, NVP-BEP800对密切相关的GHKL ATP酶、拓扑异构酶 II和结构不相关的ATP酶均无明显抑制效果。 |
激酶实验 | Competitive binding fluorescent polarization assay: Recombinant Hsp90β, TAMRA-radicicol, or various concentrations of NVP-BEP800 is added in assay buffer (50 mM TRIS pH 7.4, 5 mM MgCl2, 150 mM KCl, and 0.1% CHAPS), mixed, and incubated at room temperature for 30 to 45 minutes prior to reading. The 2D-FIDA-based HTS assay based on confocal technologies monitors the decreased fluorescence polarization on displacement of the high affinity ligand TAMRA-radicicol from Hsp90β by NVP-BEP800. The concentration of NVP-BEP800 which inhibits Hsp90β by 50% is determined from the competition curve. |
细胞实验 | Cells are exposed to NVP-BEP800 for 24 hours. Cell proliferation is determined using either sulforhodamine B for adherent cells or MTS assay for suspension cells or those showing low adherence. Cell death is determined using a ToxiLight nondestructive cytotoxicity bioassay kit. Cell cycle progression is determined by RNase A/propidium iodide staining following fixation in 70% ethanol. Caspase-3/7 activity is determined using a homogeneous caspase activity kit.(Only for Reference) |

对于不同动物的给药剂量换算,您也可以参考 更多...
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。
