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].

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].

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].
