IXA4 is a highly selective, non-toxic IRE1/XBP1s activator that induces endoplasmic reticulum (ER) proteostasis remodeling[1]. IXA4 activates IRE1/XBP1 signaling but does not fully activate the unfolded protein response (UPR) or other stress response signaling pathways[2]. IXA4 reduces the secretion of amyloid precursor protein (APP) through IRE1 activation and prevents APP-related mitochondrial dysfunction[3].
In vitro, IXA4 (30μM) treatment of mouse splenic T cells for 4 days significantly increased mitochondrial mass and mitochondrial ATP reserves in cells[4]. IXA4 (10μM) treatment of CHO7PA2 cells expressing the V717F APP (APPV717F) mutant for 18h reduced the level of β-amyloid protein (Aβ) by 50%[5].
In vivo, IXA4 (50mg/kg) was treated with diet-induced obese (DIO) mice by intraperitoneal injection for 8 weeks, which selectively activated IRE1/XBP1s signaling in the liver of mice, improved glucose homeostasis, inhibited hepatic gluconeogenesis, and reduced the expression of key lipogenic genes in the liver (including Dgat2, Scd1, and Srebf1c)[6].

| Cell experiment [1]: | |
|
Cell lines |
T cells |
|
Preparation Method |
Whole splenocytes from OT-1 mice were activated with 1μg/mL OVA peptide and expanded for 3 days with 200U/mL rhIL-2 (NCI) then split and expanded for 4 more days. IXA4 (30μM) was added at T cell activation and again at the cell split for 4 more days. Cell mitochondria were labeled with MitoTracker and then analyzed by confocal imaging and flow cytometry. |
|
Reaction Conditions |
30μM; 4 days |
|
Applications |
IXA4 treatment increased mitochondrial mass and mitochondrial ATP reserves in T cells. |
| Animal experiment [2]: | |
|
Animal models |
Diet-induced obese (DIO) mice |
|
Preparation Method |
Diet-induced obese (DIO) mice were maintained on a high-fat diet for 3 weeks. IXA4 was formulated in 10% DMSO, 30% Kolliphor EL:ethanol (2:1 ratio), 60% saline. Mice were given vehicle, IXA4 (50mg/kg) once daily by intraperitoneal injection for up to 8 weeks. Body weight and food intake were measured weekly. At sacrifice, tissues were harvested and snap frozen for processing. |
|
Dosage form |
50mg/kg/day, for 8 weeks; i.p. |
|
Applications |
IXA4 selectively activated IRE1/XBP1s signaling in the liver of DIO mice, improved glucose homeostasis, inhibited hepatic gluconeogenesis, and reduced the expression of key lipogenic genes in the liver, including Dgat2, Scd1, and Srebf1c. |

| General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |
