Biological Activity
IC50: 20 nM (IRE1α kinase activity), 200 nM (IRE1α RNase activity)[1]
GSK2850163 is a novel inhibitor of inositol-requiring enzyme-1 alpha (IRE1α) which can inhibit IRE1α kinase activity and RNase activity with IC50s of 20 and 200 nM, respectively. The increased autophosphorylation of IRE1α could be reduced in a dose-dependent manner by GSK2850163. Increasing concentrations of GSK2850163 are capable of reducing the increased XBP 1 transcriptional activity. Two additional kinases are weakly inhibited by GSK2850163: Ron (IC50=4.4 μM) and FGFR1 V561M (IC50=17 μM)[1].

Solvent & Solubility
DMSO : 67.5 mg/mL (151.21 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Ethanol : 50 mg/mL (112.00 mM; Need ultrasonic)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month. When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.25 mg/mL (5.04 mM); Clear solution
This protocol yields a clear solution of ≥ 2.25 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (22.5 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.

Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL.
1. Take μL DMSO stock solution;
2. Add μL .

Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
Protocol
PANC-1 cells are seeded into six-well plates at a density of 5.0×103 cells/well in RPMI 1640 media containing 10% FBS. Cells are cotransfected with a pGL3-5x unfolded protein response element (UPRE)-luciferase reporter containing five repetitions of the XBP-1 DNA binding site and pRL-SV40 using the FuGENE6 transfection reagent. Forty-eight hours later, cells are treated with 2.5 mg/mL tunicamycin for 1 hour, followed by GSK2850163 treatment for 16 hours. Luciferase expression is measured using Dual-Glo Luciferase Assay kit and normalized to Renilla expression levels[1].
