Overview

Information

CH-223191 CH-223191 is a potent and specific aryl hydrocarbon receptor (AhR) antagonist with IC50 of 30 nM.
In vitro

CH-223191 blocks TCDD-mediated nuclear translocation and DNA binding of AhR, and also causes the inhibition of TCDD-induced cytochrome P450 enzyme activity. In human glioblastoma cells, CH-223191downregulates the TGF-beta/Smad pathway, and reduces clonogenic survival and invasiveness. In SK-N-SH human-derived neuronal cells, CH223191 counteracts the TCDD-induced suppression of neuronal acetylcholinesterase expression. In endothelial cells, CH-223191 potentiates ICAM-1 expression and prevents RelB nuclear translocation.

In vivo

CH-223191 (10 mg/kg/day, p.o.) potently prevents TCDD-caused cytochrome P450 induction, liver toxicity, and wasting syndrome in mice.
