产品介绍

生物活性
产品描述
MS436 is a selective, small-molecule inhibitor for the BRD4 bromodomains.
靶点活性
BRD4(2):0.34 μM(Ki), BRD4(1):<0.085 μM(Ki)
体内活性
对于第一溴结构域蛋白,MS436表现出低纳摩尔亲和力(Ki=30-50 nM)。在NF-κB定向产生的小鼠巨噬细胞中,MS436能够抑制NO和IL-6的BRD4活性。
激酶实验
Fluorescence Anisotropy Binding Assay: Binding affinity of the newly synthesized diazobenzene compounds for various bromodoamins is assessed in a fluorescence anisotropy competition assay using a fluorescein isothiocyanate (FITC)-labeled MS417 as an assay probe. Competition experiments are performed with a BrD protein (0.25–1 μM) and the fluorescent probe (80 nM), and increasing concentration of unlabeled competing ligand in a PBS buffer (pH 7.4) in total volume of 80 μL Measurements are obtained after a 1 hour incubation of the fluorescent ligand and the protein at 25°C with Safire 2 microplate reader. In a competition-binding assay, fluorescent ligand concentration is ≤ 2Kd, and protein concentration was set at which 50-80% of fluorescent ligand is bound. Dissociation constant of a competing ligand is calculated with the correction to Cheng-Prussoff equation introduced by Nicolovska-Coleska and colleagues. Assuming one-site competitive binding model, the equation used to calculate Ki's from IC50 values recovered from fitting data using Prism.
细胞实验
Murine macrophage RAW264.7 cells are plated at a density of 10000 cells per well in a 96-well plate and incubated at 37 °C for 18 h. The cells are then treated with the diazobenzene bromodomain inhibitors up to 100 μL for 24 hours. At the end of the 24 hr incubation, 10 μL of the MTT solution (4 mg/ml) is added to each well and incubated at 37°C for 4 h. The supernatants are then removed and the cells were solubilized in 100 μL of 100% DMSO. The diazobenzene compounds are first dissolved in DMSO then diluted with culture medium to concentrations that ranged from 0.28 to 50000 nM. The final concentration of DMSO is adjusted to 0.05% (v/v). The extent of the reduction is measured by the absorbance at 570/630 nm using EnVison 2104 Multilabel Reader.(Only for Reference)

体内实验配液计算器

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:
TargetMol | Animal experiments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 μLTargetMol | Animal experiments 一共给药动物 10 只 ,您使用的配方为 5% TargetMol | reagent 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 μLDMSOTargetMol | reagent ( 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:50μLDMSOTargetMol | reagent 母液,添加 300 μLPEG300TargetMol | reagent 混匀澄清,再加 50μLTween 80, 混匀澄清,再加 600μLddH2OTargetMol | reagent 混匀澄清

以上为“体内实验配液计算器”的使用方法举例,并不是具体某个化合物的推荐配制方式,请根据您的实验动物和给药方式选择适当的溶解方案。
