2.0mg/ml

Taking the 1 mL working solution as an example, add 20 μL of 100 mg/ml clarified DMSO stock solution to 300 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify it; then continue to add 630 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.

* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

生物活性

製品説明	PYR-41 is the first cell-permeable inhibitor of ubiquitin-activating enzyme E1, with no activity at E2. PYR-41 induce apoptosis.
in vitro	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]

プロトコル(参考用のみ)

キナーゼアッセイ	ubiquitylation reaction assay
キナーゼアッセイ	Rabbit or mouse E1 (~250 ng) is incubated with ^32P-ubiquitin in 1 譺eaction 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 ?reactionbuffer 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.
