产品名称

产品介绍
4μ8C (IRE1 Inhibitor III)是IRE1α的小分子抑制剂。
生物活性

4μ8C (IRE1 Inhibitor III) is a small-molecule inhibitor ofIRE1α.

体外研究
(In Vitro)

When applies to the media of ER stressed cultured cells, 4μ8C (IRE1 Inhibitor III) inhibits Xbp1 splicing in a concentration-dependent manner. 4μ8C dissociates slowly from IRE1, but ishout of inhibitor leads to rapid recovery of Xbp1 splicing in cells[1].The IRE1 endoribonuclease inhibitor 4μ8c prevents the splicing of the XBP1 mRNA in response to ER stress caused by mutant proinsulin production[2]. The inositol-requiring enzyme 1α (IRE1α) is a serine-threonine kinase that plays crucial roles in activating the unfolded protein response. 4μ8C treatment dramatically inhibits IL-4 production by CD4+T cells under Th0 conditions because both the IL-4 levels in the culture supernatant and the percentage of IL-4 positive cells are reduced by 4μ8C treatment. In addition, both IL-5 and IL-13 production are significantly reduced upon treatment with 4μ8C[3].

体内研究
(In Vivo)

4μ8c (IRE1 Inhibitor III) (i.p. injection; 10 mg/kg/day for 4 more weeks) leads to a significant reduction (45.2%) in atherosclerotic lesion area in en face aorta preparations. 4μ8c can effectively mitigate plaque development in mice[4].
4μ8C (orally; 10, 50, or 100 mg/kg) suppresses passive cutaneous anaphylaxis (PCA) in mice (ED50 = 25.1 mg/kg)[5].
4μ8C reverses the ER stress-dependent loss of several known RIDD targets, with an EC50of approximately 4 μM, approximating that of inhibition of XBP1 target gene activation[1].

    请依序添加每种溶剂: 10% DMSO    40%PEG300   5%Tween-80   45% saline

    Solubility: ≥ 2.08 mg/mL (10.19 mM); Clear solution

    此方案可获得 ≥ 2.08 mg/mL (10.19 mM,饱和度未知) 的澄清溶液。
