both drugs increased p-nitroanisole demethylase activity strikingly and aniline hydroxylase activity moderately , but produced little change in aminopyrine demethylase activity . alpha-naphthoflavone , which is known to be a specific inhibitor of aryl hydrocarbon hydroxylase induced by polycyclic aromatic hydrocarbons , inhibited at low concentrations p-nitroanisole demethylase activity of rats previously treated with both drugs .
