fussnote The relative abilities of substituted phenols to induce drug-metabolizing enzymes were measured either 24 hr after a single dose or after 6-10 daily doses. The phenols carried various combinations of the substituents, methyl, ethyl, isopropyl, tert-butyl, tert-amyl, phenyl, benzyl, methoxy, methoxymethyl, hydroxymethyl, dimethylaminomethyl and nitro. When the effect was measured 24 hr after a single dose, a close relationship was found between the induction of drug-metabolizing enzymes and the lipid-water partition coefficient of the test compound. When the effect was measured after six daily doses this relationship was less distinct; further dosing could lead either to an accentuation or to a diminution of the effect. One compound which provided less evidence of induction after six doses than after a single dose was 2,6-di-tert-butyl-4-methoxymethylphenol. This regression of enzyme activity on repeated dosing was not related to any histological change or to the amount or distribution of histochemically-demonstrable glucose 6-phosphatase in the liver. Many of the substituted phenols also induced uridine diphosphate glucose dehydrogenase, an effect apparently unrelated either to the lipid-water partition coefficient or to the induction of drug-metabolizing enzymes. Liver enlargement was not invariably related to the induction of either drug-metabolizingactivities or uridine diphosphate glucose dehydrogenase.
