title: [A fluorometic test for microsomal monooxygenase activity in the rat liver with scoparone as substrate (author's transl)].
abstract: A sensitive fluorometric test for the determination of monooxygenase activity in liver microsomes from rats is described. The assay is based on the O-demethylation of 6,7-dimethoxycoumarin (scoparone) to 7-hydroxy-6-methoxycoumarin and 6-hydroxy-7-methoxycoumarin. Pretreatment of rats with phenobarbital or polycyclic hydrocarbons (benzo[a]pyrene, 3-methylcholanthrene) causes a significant increase in the amount of microsomal dealkylation activity.
