제품 설명

Tapinarof (WBI-1001) is a natural aryl hydrocarbon receptor (AhR) agonist with an EC₅₀ of 13 nM. Tapinarof resolves skin inflammation in mice^[1].

IC₅₀ & Target

In Vitro

Tapinarof activates the AhR pathway through direct binding. Tapinarof dose-dependently induces nuclear translocation of AhR in immortalized keratinocytes (HaCaT) (EC₅₀=0.16 nM)^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Tapinarof acts through AhR to reduce inflammation in IMQ-treated mice. AhR-sufficient mice on a C57Bl/6 background exhibit a reduced clinical score after treatment with Tapinarof or 6-formylindolo(3,2-b)carbazole (FICZ). In contrast, AhR KO mice do not respond to the anti-inflammatory effects of Tapinarof. FICZ is used as a comparator in these studies and yields similar results, with dramatically reduced inflammatory responses in wild-type, but not AhR KO mice^[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.

Protocol 1

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (9.83 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.
Protocol 2

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (9.83 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.
Protocol 3

Add each solvent one by one: 10% DMSO 90% Corn Oil
Solubility: ≥ 2.5 mg/mL (9.83 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Cell Assay ^[1]	HaCaT cells (10,000 cells/well) are cultured in 96-well Greiner μCLEAR plates in 100 μL DMEM with HEPES, Glutamax and 10% fetal bovine serum to confluence. Media is replaced with 100 μL media containing 0.2% heat-inactivated, charcoal-stripped fetal bovine serum and incubated overnight. Titrating concentrations of Tapinarof (10^-8 μM ,10^-6 μM, 10^-4 μM, 0.01 μM, and 1 μM) are added for 30 minutes followed by washing and fixing in ice-cold methanol:acetone (50:50). Samples are blocked with 3% BSA for 1 hour, and then washed again in phosphate buffered saline with 0.1% Tween-20. Next, cells are stained with 50 μL of 1:50 dilution anti-AhR antibody in 3% BSA, followed by 50 μL secondary antibody (1:500 dilution chicken anti-rabbit AlexaFluor488 and 1:2,000 dilution Hoechst 33342) in 3% BSA/phosphate buffered saline.

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
