| 包装规格: | 5mg 10mg 25mg 50mg 100mg in glass bottle |
| 产品简介: | 一种有效的选择性 CREB 结合蛋白 (CBP)/p300 抑制剂。IC50 为 2.9 和 1.1 μM。 |
| 溶解性: | 溶于DMSO(≥250mg/mL) |
| 储备液保存: | -80°C, 2 years -20°C, 1 year |
| 体内实验: | 1、请依序添加每种溶剂: 10% DMSO→40% PEG300→5% Tween-80→45% Saline Solubility: ≥ 2.08 mg/mL (4.73 mM); 澄清溶液 此方案可获得 ≥ 2.08 mg/mL(饱和度未知)的澄清溶液。 以 1 mL 工作液为例,取 100 μL 20.8 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中,混合均匀;再向上述体系中加入 50 μL Tween-80,混合均匀;然后再继续加入 450 μL 生理盐水 定容至 1 mL。 <1mg/ml表示微溶或不溶。 普西唐提供的所有化合物浓度为内部测试所得,实际溶液度可能与公布值有所偏差,属于正常的批间细微差异现象。 请根据产品在不同溶剂中的溶解度选择合适的溶剂配制储备液;一旦配成溶液,请分装保存,避免反复冻融造成的产品失效。 |
| 靶点: | IC50: 1.1 μM (p300), 2.9 μM (CBP) |
| 体外研究: | EML 425 (EML425, Compound 7h) is a potent and selective reversible inhibitor of CBP/p300, noncompetitive versus both acetyl-CoA and a histone H3 peptide, and endows with good cell permeability. EML 425 inhibits both p300 and CBP (IC50 values of 2.9 and 1.1 μM, respectively) while being practically inactive against the enzymes general control non derepressible-5 (GCN5) and p300/CBP-associated factor (PCAF). EML 425 induces a marked and time-dependent reduction in the acetylation of lysine H4K5 and H3K9 in U937 cells. EML 425 is shown to be a reversible inhibitor, noncompetitive versus both acetyl-CoA and a histone H3 peptide, and able to bind both the free enzyme and the enzyme-substrate complex, even with unequal affinity constants. The best scoring docking poses suggest that the binding site for EML 425 is an alternative pocket lying near the substrate lysine binding groove and close to the acetylation site. |
