产品描述 PYR-41 is the first cell-permeable inhibitor of ubiquitin-activating enzyme E1, with no activity at E2.
靶点活性 E1:< 10 μM
体外活性 PYR-41 (50 μM) inhibits activity of ubiquitin-activating enzyme E1 by over 90%. PYR-41 could be a target for nucleophilic attack and potentially reacts with the active site cysteine of E1. PYR-41 efficiently blocks cyclin E degradation. PYR-41 decreases the level of E1fUb thioesters in cells with a IC50 of between 10 and 25 μM, and prevents proteasome inhibitor–induced accumulation of ubiquitylated proteins. PYR-41 increases total sumoylation in cells and in cell harboring temperature-sensitive E1. PYR-41 is able to inhibit both proteasome-dependent and proteasome-independent activities of ubiquitylation. PYR-41 (50 μM) attenuates 1 ng/mL IL-1α-mediated nuclear factor-κB activation by >60% through preventing the downstream ubiquitylation and proteasomal degradation of IκBα. PYR-41 inhibits degradation of p53 and activates the transcriptional activity of p53, which enable its differentially killing transformed p53-expressing cells. [1] PYR-41 blocks ubiquitination reactions but paradoxically leads to the accumulation of high MW ubiquitinated proteins. PYR-41 also has equal or greater inhibitory activity against several deubiquitinases (DUBs) in intact cells and purified USP5 in vitro. PYR-41 also mediates cross-linking of specific protein kinases (Bcr-Abl, Jak2) to inhibit their signaling activity. [1]
激酶实验 Rabbit or mouse E1 (apper 250 ng) is incubated with 32P-ubiquitin in 1× reaction buffer [50 mM Tris (pH 7.4), 0.2 mM ATP, 0.5 mM MgCl2] at room temperature for 15 min. In some experiments, the His-tagged mouse E1 is bound to TALON cobalt affinity resin before carrying out incubations and reactions. Mouse E1 and 32P-ubiquitin are added to the beads in 1× reaction buffer and incubated as for E1 reactions. Samples are heated in nonreducing SDS-PAGE sample buffer and resolved by SDS-PAGE. Thioesters with ubiquitin are visualized by Storm PhosphoImager.

TargetMol Calculator 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: 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。
