title: Induction of rat-hepatic microsomal cytochrome P-450 and aryl hydrocarbon hydroxylase by 1,3-benzodioxole derivatives.
abstract: Several 1,3-benzodioxoles (BD) and related compounds were studied in relation to their ability to generate metabolite complexes with hepatic cytochrome P-450 following administration in vivo to rats. BD derivatives that formed stable metabolite complexes with cytochrome P-450 were considerably more effective inducers of cytochrome P-450 and aryl hydrocarbon (benzo[alpha]pyrene) hydroxylase (AHH) activity than derivatives that did not form stable complexes. Linear regression analysis showed that AHH activity was well correlated (r = 0.980) with total (i.e. complexed plus uncomplexed) cytochrome P-450 content and was not correlated with levels of uncomplexed cytochrome P-450. Aminopyrine N-demethylase (APDM) activity in hepatic microsomes from rats treated with 1,3-benzodioxoles was moderately correlated in a linear relationship with uncomplexed levels of cytochrome P-450 and not with total cytochrome P-450.
