Biological Activity
IC50: 0.6 μM (USP14), 20 μM (IsoT/USP5)[1]
IU1-47 is essentially inactive on free USP14 (USP14 that is not bound to the proteasome). IU1-47 (25 μM) antagonizes USP14 deubiquitinating activity and stimulates substrate degradation in vitro[1].
IU1-47 stimulates tau degradation principally via the ubiquitin-proteasome system. IU1-47 (3 μM, 10 and 30 μM; 48 hours) significantly decreases Tau and phosphotau species Ser-202/Thr-205 levels in murine cortical primary neurons. The level of USP14 itself does not change[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Solvent & Solubility
DMSO : 16.67 mg/mL (50.39 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, 2 years; -20°C, 1 year. When stored at -80°C, please use it within 2 years. When stored at -20°C, please use it within 1 year.

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: ≥ 1.67 mg/mL (5.05 mM); Clear solution
This protocol yields a clear solution of ≥ 1.67 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (16.7 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: ≥ 1.67 mg/mL (5.05 mM); Clear solution
This protocol yields a clear solution of ≥ 1.67 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (16.7 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.
