In the presence of the CYP2E inhibitor 4-methylpyrazole, a decrease in naphthalene covalent binding was observed, suggesting that the formation of the 1,2-epoxide may be the main culprit contributing to naphthalene covalent binding.

Between days 1 and 2 after administration, hepatic P450s were significantly induced as follows: CYP3As, 7.1x; CYP1As, 1.6x; CYP2E1, 1.5x; CYP2Cs, 1.6x.
In particular, several volatile sesquiterpenes, naphthalene-derived aromatics and 4,4-dimethyl-13alpha-androst-5-ene were decreased in the ST-cedar bedding, suggesting that these may be responsible for P450 induction.

The absence of a role for CYP2E1-generated metabolites (primarily alkyl oxidation vs. ring-oxidation) in mouse pulmonary effects was demonstrated by the lack of protection from styrene toxicity by CYP2E1 inhibitor, or reduction of toxicity in CYP2E1-knockout mice, and lack of lung toxicity of the primary metabolite of ethylbenzene.
For coumarin, naphthalene, and styrene, inhibition of toxicity with inhibition of CYP2F2 has been demonstrated.
