背景说明 |
ITE 是一种有效的内源性芳香烃受体 (AhR) 激动剂,能够直接与 AHR 结合。ITE 具有免疫抑制活性。 |
生物活性 |
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.[1-3] |
IC50 |
Ki: 3 nM (AhR)[1] |
In Vitro |
ITE 是 AhR 的内源性激动剂,直接与 AHR 结合,Ki 为 3 nM[1]。ITE (0.03-30 mg/mL) 降低抗原特异性 T 细胞增殖反应[2]。ITE 在 10 和 20 μM 时有效抑制人肺动脉内皮细胞 (HPAEC) 的生长,但在 0.01-5 μM 时没有效果。ITE 在 10 和 20 μM 时不影响 HPAEC 的细胞周期进程,或在 20 μM 时诱导 HPAEC 中裂解的 caspase-3 蛋白的表达。此外,ITE (20 μM) 可提高 CYP1A1 和 CYP1B1 mRNA 水平并降低 HPAECs[3]中 AhR 蛋白的水平。 |
In Vivo |
ITE (200 μg,ip) 显著抑制小鼠实验性自身免疫性葡萄膜炎 (EAU) 的发展。ITE 降低小鼠中表达 IFN-γ、IL-17 或 IL-10 的细胞比例。ITE 还抑制小鼠 LN 细胞分泌炎性细胞因子[2]。 |
细胞实验 |
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]. |
动物实验 |
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]. |
