Hepatic microsomal enzyme induction by 2,2', 3,3', 4,4'- and 2,2', 3', 4,4', 5-hexachlorobiphenyl. Academic Article uri icon

abstract

  • In an attempt to resolve conflicting reports in the literature, the effects of 2, 2', 3, 3', 4, 4'-hexa- and 2, 2', 3', 4, 4', 5-hexachlorobiphenyl on the hepatic microsomal drug-metabolizing enzymes were evaluated in the immature male rat. By comparison with the effects of the classical enzyme inducers, phenobarbitone (PB) and 3-methylcholanthrene (MC), 2, 2', 3, 3', 4, 4'-hexachlorobiphenyl, irrespective of its synthetic route, exhibited PB- and MC-type characteristics; the most prominent feature of the latter being a seven-fold increase in 4-chlorobiphenyl hydroxylase activity. 2, 2', 3', 4, 4', 5-Hexachlorobiphenyl also resembled a mixed (PB + MC)-type inducer although its MC-type characteristics were more pronounced than those of 2, 2', 3, 3', 4, 4'-hexachlorobiphenyl. 1980.
