[Changes in the enzymic activity of monooxygenase components of rat hepatocytes after administration of tilorone]

It is established that tilorone-hydrochloride, the antiviral agent, stimulating the interferon synthesis in the organism of animals under experiment inhibits monooxygenase reactions in the albino rat hepatocytes being administered in combination with phenobarbital and 20-methylcholanthrene. The tilorone effect on the N- and O-demethylase activity of the liver microsomes in vitro was studied. It is established that the rate of dimethylaniline N-demethylation and anisole O-demethylation in this case lowers considerably, the character of the kinetic curves being unchanged.
