PROTAC STAT3 degrader-3
Based on 1 Customer Validation
PROTAC STAT3 degrader-3 is a STAT3 PROTAC degrader. PROTAC STAT3 degrader-3 recruits the E3 ubiquitin ligase CRBN and induces the degradation of STAT3 protein. PROTAC STAT3 degrader-3 inhibits the proliferation of malignant tumor cells. PROTAC STAT3 degrader-3 can be used for the research of non-small cell lung cancer and liver cancer.

PROTAC STAT3 degrader-3 (Compound S3D1) (96 h) inhibits the proliferation of H1299 and HepG2 cells, with IC50 values of 10.06 and 14.97 μM[1].
PROTAC STAT3 degrader-3 (1-20 μM; 0-48 h) induces concentration-dependent and time-dependent degradation of STAT3 protein in H1299 and HepG2 liver cancer cells[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Cell Line:H1299 non-small cell lung cancer cells and HepG2 hepatocellular carcinoma cells
-
Concentration:1, 5, 10, 15 and 20 μM (24 h incubation); 5 μM (time-course incubation)
-
Incubation Time:24 h (concentration gradient); 0, 3, 6, 12, 24, 30, 36 and 48 h (time-course)
-
Result:Reduced STAT3 protein levels in a concentration-dependent manner after 24 h treatment with 1-20 μM, with higher concentrations causing more pronounced degradation.
Caused gradual reduction of STAT3 protein levels over 48 h of 5 μM treatment, with the degradation effect strengthening as incubation time increased.

Solvent & Solubility
DMSO : 100 mg/mL (128.09 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 (3.20 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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (3.20 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 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
