体外研究 |
NI-57 is an inhibitor of bromodomain and plant homeodomain finger-containing (BRPF), with IC50s of 3.1, 46 and 140nM for BRPF1, BRPF2 (BRD1) and BRPF3,respectively. NI-57 binds the BRD of BRPF1 with a Kd of 31 ± 2nM, BRD1 with a Kd of 110±13nM, and BRPF3 with a Kd of 410±47nM, whereas binding to BRD9 is weaker (Kd 1000±130nM) measured by isothermal titration calorimetry.NI-57 shows less active effect on BRD9 (IC50, 520nM) and BRD4 (BD1 (IC50,3700nM), TRIM24 (IC50,1600nM). NI-57 also inhibits BRPF BRDs in the nucleus, but shows little effect on the proliferation of many cancer cell lines with GI50s of 10.4μM (NCI-H1703 cells),14.7μM (DMS114), 15.6μM (HRA-19), and 16.6μM (RERF-LC-Sq1). Furthermore,Inhibition on BRPF1 of NI-57 (10μM) reduces the gene expression of CCL-22 by 27.7 ± 9.4%. |

推荐实验方法(仅供参考)

激酶实验: |
|
All reagents are diluted in the recommended buffer (50mMHEPES, 100mM NaCl, 0.1% BSA;pH=7.4) supplemented with 0.05% CHAPS and allowed to equilibrate to room temperature prior to addition to plates. 4mL of HIS-tagged protein is added to low-volume 384-well plates,followed by 4mL of either buffer, non-biotinylated peptide, solvent or compounds (NI-57,etc.). Plates are sealed and incubated at room temperature for 30 minutes, before the addition of 4mL biotinylated peptide, resealing and incubation for a further 30 minutes. 4mL of streptavidin-coated donor beads (25µg/mL) and 4 µL of nickel chelate acceptor beads (25µg/mL) are then added under low light conditions. Plates are foil sealed to protect from light, incubated at room temperature for 60 minutes and read on a PHERAstar FS plate reader using an AlphaScreenTM 680 excitation/570 emission filter set. IC50s are calculated in GraphPad Prism 5.Results for compounds (NI-57, etc.) dissolved in DMSO are normalised against corresponding DMSO controls prior to IC50 determination, which are given as the final concentration of compound in the 20µL reaction volume. |
本计算器可帮助您计算出特定溶液中溶质的质量、溶液浓度和体积之间的关系,公式为:
质量 (g) = 浓度 (mol/L) x 体积 (L) x 分子量 (g/mol)
摩尔浓度计算公式
用本工具协助配置特定浓度的溶液,使用的计算公式为:
开始浓度 x 开始体积 = 最终浓度 x 最终体积
稀释公式
稀释公式一般简略地表示为:C1V1 = C2V2 ( 输入 输出 )

混匀澄清方案所需的各种助溶剂如: DMSO , PEG300 / PEG400 , Tween 80 , SBE-β-CD , 玉米油 等, 均可点击跳转或在网站搜索购买。
计算结果:
工作液浓度: mg/ml;
DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL,
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL Saline/PBS/ddH2O,混匀澄清。
1. 首先保证母液是澄清的;
2.
一定要按照顺序依次将溶剂加入,进行下一步操作之前必须保证上一步操作得到的是澄清的溶液,可采用涡旋、超声或水浴加热等物理方法助溶。
