Isosafrole, piperonyl butoxide, and 5-t-butyl-1,3-benzodioxole were unable to displace 2,3,7,8-tetrachlorodibenzo-p-dioxin or 3-methylcholanthrene from either the Ah receptor or the 3-4S binding peak, in vitro.

To investigate the role of AHR in fish development, medaka embryos were treated with agonist (2,3,7,8-tetrachlorodibenzo-p-dioxin), antagonists (alpha-naphthoflavone and resveratrol), and inhibitor (piperonyl butoxide) of cytochromes (Cyts) P450 encoded by a battery of target genes.

Increases in 1a-2 and 2b-10 protein were observed for ISO and PBO in both strains of mice, suggesting an Ah receptor-independent mechanism for induction of these isozymes; 1a-1 induction, however, was seen only in C57 mice.
Piperonyl butoxide was the more potent inducing agent in both strains.

The mechanism of action of TCDD at the cellular level is primarily mediated through the aryl hydrocarbon receptor (AhR).
In this study, the role of radical oxygen species and mixed function oxidize (MFO; cytochrome P4501A) in the mechanism of TCDD-induced abnormalities and lethality were examined by co-injecting radical scavengers and an MFO inhibitor (piperonyl butoxide).
