QC-01–175
Based on 1 Customer Validation
QC-01-175 is a Tau PROTAC degrader, with Kd values of 1.2 μM, 1.7 μM and 2.5 μM for wild-type, A152T mutant and P301L mutant tau-441 proteins, respectively. QC-01-175 binds to both Tau and CRBN, triggering ubiquitination and proteasomal degradation of Tau. QC-01-175 preferentially targets disease-associated Tau proteins in frontotemporal dementia. QC-01-175 inhibits MAO activity, with an IC50 of 8.56 μM. QC-01-175 suppresses the elevation of ROS levels. QC-01-175 can be used in studies related to frontotemporal dementia and amyotrophic lateral sclerosis.

Cereblon |
QC-01-175 binds to recombinant wild-type, A152T mutant, and P301L mutant tau-441 proteins respectively, with corresponding KD values of 1.2 μM, 1.7 μM, and 2.50 μM[1].
QC-01-175 (10 μM; 4 h) significantly reduces the level of pTau-S396 in SH-SY5Y cells treated with ALS SNs[2].
QC-01-175 (60 min) inhibits MAO activity with an IC50 of 8.56 μM, and its off-target MAO inhibitory effect is reduced compared with the parent compound T807[1].
QC-01-175 (10 μM; 4 h) prevents the increase in reactive oxygen species levels in SH-SY5Y cells induced by tau protein and ALS sensory neurons (SNs)[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Result:Showed no effect on pTau-S396 levels in ALS SNs-treated cells across all time points at 1 μM.
Reduced pTau-S396 levels in ALS SNs-treated cells after 4 h, with the effect absent after 24 h at 10 μM.
Caused a significant decrease in pTau-S396 levels in ALS SNs+QC-01-175-treated cells compared to ALS SNs-only treated cells (one-way ANOVA, F(3,12) = 3.699, p = 0.0429; Tukey’s test, p = 0.0328) in a confirmatory assay at 10 μM for 4 h.

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: ≥ 5 mg/mL (7.98 mM); Clear solution
This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 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.
