产品详情
ISRIB (trans-isomer)是高效的PERK抑制剂,IC50值为 5 nM。ISRIB 可有效逆转 eIF2α 磷酸化的作用 (IC50=5 nM)。
生物活性
ISRIB (trans-isomer) is a potent inhibitor of PERK with an IC 50 of 5 nM. ISRIB potently reverses the effects of eIF2α phosphorylation (IC 50 =5 nM).

IC50 & Target[1][2]
PERK 5 nM (IC50)
体外研究(In Vitro)
Trans-ISRIB is 100-fold more potent (IC50=5 nM) than cis-ISRIB (IC50= 600 nM), indicating that the compound’s interaction with its cellular target is stereospecific. ISRIB reduces the viability of cells subjected to PERK-activation by chronic endoplasmic reticulum stress. ISRIB substantially reverses the translational effects elicited by phosphorylation of eIF2α and induces no major changes in translation or mRNA levels in unstressed cells. eIF2α phosphorylation-induced stress granule (SG) formation is blocked by ISRIB. has not independently confirmed the accuracy of these methods. They are for reference only.
体内研究(In Vivo)
ISRIB increases long-term memory in rodents. ISRIB-treated mice display significant enhancement in spatial and fear-associated learning. ISRIB displays a half-life in plasma of 8 hr and readily crossed the blood-brain barrier, quickly equilibrating with the central nervous system. has not independently confirmed the accuracy of these methods. They are for reference only.

1:一般建议:溶解度为Medlife测试数据,可能与文献描述存在差异。这是由于生产工艺和批次不同产生的正常现象。为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同批次产品溶解度各有差异,仅做参考,具体以实验方案为准。

2:储存条件:粉末-20°C一般情况可以保存3年,溶于溶剂-80°C一般情况可以保存1年。不同产品及不同批次产品可能存在差异,请细致阅读产品信息,并辅助参考相关文献描述。

The molarity calculator equation
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
The dilution calculator equation
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2
