Biological target:
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.
In vitro activity:
While NICD1 was barely detectable in MCF7 and MDA-MB-436, ITE significantly reduced NICD1 protein levels in MDA-MB-231 and MDA-MB-157 cells (Fig. 3B). Thus, these data indicate for the first time that in TNBC cells, ITE reduces JAG1 expression and NICD1 signaling. Reference: J Am Heart Assoc. 2021 Jul 6;10(13):e020502. https://pubmed.ncbi.nlm.nih.gov/32032581/
In vivo activity:
An increased number of Tregs in the infarcted myocardium was observed in ITE‐treated mice compared with control mice at 5 days after MI (Figure 2D). Collectively, the results show that ITE treatment increases the Foxp3+ Treg populations in the lymph nodes, spleen, and infarcted myocardium.

Note: There can be variations in solubility for the same chemical from different vendors or different batches from the same vendor. The following factors can affect the solubility of the same chemical: solvent used for crystallization, residual solvent content, polymorphism, salt versus free form, degree of hydration, solvent temperature. Please use the solubility data as a reference only. Warming and sonication will facilitate dissolving. Still have questions? Please contact our Technical Support scientists.

Preparing Stock Solutions
