YQ128
Based on 1 publication(s) in Google Scholar
YQ128 is a potent and selective second-generation NLRP3 (NOD-like receptor P3) inflammasome inhibitor with an IC50 of 0.30 μM. YQ128 significantly and selectively suppresses the production of IL-1β, but not TNF-α, and it can cross the BBB to reach the CNS. YQ128 has anti-inflammatory activity. YQ128 is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.

NLRP3 0.30 μM (IC50) |
IL-1β |
YQ128 (0.3-100 µM; 30 mins) dose dependently suppressed the release of IL-1β from peritoneal macrophages upon LPS/ATP challenge with an IC50 of 1.59 µM[1].
YQ128 (20 µM; 2 hours) shows no significant toxic effects on hCMEC/D3 cells[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Result:Suppressed the release of IL-1β from peritoneal macrophages upon LPS/ATP challenge with an IC50 of 1.59 µM.
YQ128 (oral; 20 mg/kg) shows delayed gastrointestinal absorption with a tmax and cmax of 12 h and 73 ng/mL, respectively. Oral bioavailability (Foral) is estimated as 10%[1].
YQ128 exhibits extensive extravascular distribution with a large steady-state volume of distribution (Vdss) of 8.5 L/kg and rapid total clearance (CLtot) of 41 mL/min/kg[1].
YQ128 (10 mg/kg) has been shown to trigger IL-1β production in a NLRP3- dependent manner in C57BL/6 mice[1].

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: ≥ 2.08 mg/mL (3.82 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.

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.
