Description

ITE is a potent endogenous agonist of aryl hydrocarbon receptor (AhR), binding directly to AHR, with a Ki of 3 nM. ITE also has immunosuppressive activity.

IC50 & Target

Ki: 3 nM (AhR)[1]

In Vitro

ITE is an endogenous agonist of AhR, binding directly to AHR, with a Ki of 3 nM[1]. ITE (0.03-30 mg/mL) decreases the antigen-specific T-cell proliferative responses[2]. ITE potently inhibits human pulmonary artery endothelial (HPAECs) growth at 10 and 20 μM, but shows no effect at 0.01-5 μM. ITE does not affect cell cycle progress of HPAECs at 10 and 20 μM, or induce expression of cleaved caspase-3 protein in HPAECs at 20 μM. In addition, ITE (20 μM) elevates CYP1A1 and CYP1B1 mRNA levels and decreases the levels of AhR protein in HPAECs[3].

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

In Vivo

ITE (200 μg, i.p.) significantly suppresses the development of experimental autoimmune uveitis (EAU) in mice. ITE reduces the proportions of cells expressing IFN-γ, IL-17, or IL-10 in mice. ITE also suppresses the secretion of inflammatory cytokines by LN cells in mice[2].

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    90% Corn Oil

    Solubility: ≥ 2.67 mg/mL (9.33 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.67 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 (26.7 mg/mL) to 900 μL Corn oil, and mix evenly.

  • Protocol 2

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: 2.08 mg/mL (7.26 mM); Suspended solution; Need ultrasonic

    This protocol yields a suspended solution of 2.08 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

    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.

For the following dissolution methods, please prepare the working solution directly. It is recommended to prepare fresh solutions and use them promptly within a short period of time.
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:  17% Polyethylene glycol 12-hydroxystearate in Saline

    Solubility: 10 mg/mL (34.93 mM); Suspended solution; Need ultrasonic

Cell Assay
[3]

Subconfluent cells (25, 000 cells/well) are seeded in 96-well plates. Cells are treated with ITE at 5, 10 and 20 µM or DMSO (0.1% v/v) in ECM for 2, 4 or 6 days with a change of ECM containing DMSO or ITE every other day (5 wells/treatment). At the end of treatment, cells are incubated with MTT reagent for 4 hr, and solubilized in crystal dissolving solution (100 µL/well) for 20 min. The absorbance is determined at 570 nm using the microplate reader[3].

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

Animal Administration
[2]

Mice[2]
Eight- to 12-week-old female B10.A mice is used in the assay. Daily treatment starts on day 0 and consists of 200 μg of ITE suspended in 0.2 mL PBS, given intraperitoneally. Control mice are similarly treated with 0.2 mL of the vehicle, PBS containing 3.6% DMSO[2].

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.
