QL-1200186
Based on 1 Customer Validation
QL-1200186 is a selective, orally active, allosteric inhibitor targeting the tyrosine kinase TYK2 pseudokinase domain JH2 (IC50=0.06 nM, TYK2 JH2), with 164-fold selectivity over TYK1 JH2 (IC50=9.85 nM，TYK1 JH2). QL-1200186 first stabilizes the TYK2 JH2 conformation, inhibits the activity of the JH1 catalytic domain, and blocks the IFNα, IL-12/IL-23-mediated JAK-STAT signaling pathway. QL-1200186 can inhibit the production of Th1/Th17 cell-related cytokines (such as IFNγ, IL-23), reduce immune cell activation, and has no significant effect on JAK1/2/3 kinase activity. QL-1200186 can significantly improve skin inflammation in the Imiquimod (HY-B0180)-induced psoriasis mouse model and reduce the Psoriasis Area and Severity Index (PASI) score. QL-1200186 can be used in the study of autoimmune diseases such as psoriasis and systemic lupus erythematosus (SLE).

In Vitro
QL-1200186 (1-10 μM; 30 min+15 min) inhibits IFNα-induced STAT1 phosphorylation (pSTAT1) in CD3+ T cells with an IC50 of 1.61 nM; in NK-92 cells and Th17 cells, the IC50s for IL-12-induced IFN-γ expression and IL-23-induced pSTAT3 are 32.48 nM and 1.026 nM, respectively[1].
QL-1200186 (1-10 μM; 48 h) inhibits IFNα-induced pSTAT5 in human PBMCs with an IC50 of 7.26 nM[1].

In Vivo:
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 (5.15 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.
