ST2-IN-1
Based on 1 Customer Validation
ST2-IN-1 is a ST2 inhibitor. ST2-IN-1 blocks the binding interaction between ST2 and IL-33, thereby attenuating the downstream ST2/IL-33 signaling pathway. ST2-IN-1 reduces IL-1β release from mast cells and alleviates ST2 upregulation in cells. ST2-IN-1 can be used for research on inflammatory and immune-related diseases.

Biological Activity
ST2-IN-1 (Compound 31) inhibits the binding of ST2/IL-33 in a cell-free AlphaLISA assay with an IC50 of 7 μM[1].
ST2-IN-1 inhibits ST2/IL-33-mediated NF-κB activation in ST2-overexpressing HEK293 HEKBlue reporter cells, with an IC50 of 7.19 μM[1].
ST2-IN-1 (10-30 μM; 24 h) dose-dependently inhibits IL-1β release from human LAD2 mast cells co-stimulated with IL-33 and 48/80[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Cell Line:human LAD2 mast cells
-
Concentration:10 μM, 30 μM
-
Incubation Time:24 h (ST2-IN-1 treatment); 30 min (48/80 stimulation)
-
Result:Dose-dependently reduced IL-1β release from LAD2 cells co-stimulated with IL-33 and 48/80.
Yielded a partial reduction in IL-1β levels at 10 μM compared to the IL-33 + 48/80 control group.
Yielded a greater reduction in IL-1β levels at 30 μM compared to the IL-33 + 48/80 control group.

Solvent & Solubility
DMSO : 100 mg/mL (217.59 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
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: ≥ 2.5 mg/mL (5.44 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.
Please enter the basic information of animal experiments:

Recommended: Prepare an additional quantity of animals to account for potential losses during experiments.
Please enter your animal formula composition:

The co-solvents required include: DMSO, . All of co-solvents are available by MedChemExpress (MCE). , Tween 80. All of co-solvents are available by MedChemExpress (MCE).
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 .
μL , mix evenly;
3. Then add μL Tween 80, mix evenly;
4. Then 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.
