Use of inhibitors of the P-450 and P-448 isoenzymes (SKF-525A, piperonyl butoxide and ellipticine) supported the concept that only the P-448 isoenzyme is involved in the inhibition of the decarboxylase by the halogenated biphenyls. |

Biochem J. 1986 Sep 15;238(3):871-8. Although, in further studies, total microsomal cytochrome P-450 content and ethoxyphenoxazone de-ethylase activity reached a peak a few days after dosing and had declined significantly at the time of maximum inhibition of the decarboxylase, additional treatment of HCB-dosed mice with a cytochrome P1-450 inducer, beta-naphthoflavone, enhanced the inhibition, whereas piperonyl butoxide, an inhibitor of cytochrome P-450, partially protected. |

Biochem J. 1986 Jul 1;237(1):63-71. We conclude that the mechanism of the uroporphyrin accumulation cannot be due to covalent binding of activated metabolites of halogenated compounds to uroporphyrinogen decarboxylase. Reversal of the accumulation by piperonyl butoxide.. |

Uroporphyrinogen decarboxylase activity was unchanged by drug and iron treatments. Inhibitors of P-450-phenobarbital, SKF525A and piperonyl butoxide, as well as cadmium and cycloheximide prevented the accumulation produced by glutethimide + iron, even though, except with cycloheximide, these substances further increased synthase activity. |

Toxicology. 1981;19(3):185-96. Addition of the monooxygenase-inhibitor piperonyl butoxide or decreased the irreversible binding of 14C-metabolites. Since none of the main HCB-metabolites could induce a pathological pattern, a reactive intermediate capable of reacting with or thiol-groups of uroporphyrinogen decarboxylase (UROG-D) is believed to be responsible for the inhibition of UROG-D. |
