1. Beagle dogs were treated orally (10 mg/kg) with para-chloro-, para-fluoro- and para-methyl-phenylpiperazine derivatives, and urine was collected for 72 h after treatment. 2. Metabolites were extracted, converted into trimethylsilyl (TMS) derivatives and examined by g.l.c.-mass spectrometry. 3. The metabolites fall into two main groups, N-desphenylated metabolites, which result from N-desphenylation, and N-phenyl metabolites. 4. Two kinds of hydroxylated metabolites were found. Some lost the…

BIOACTIVATION OF THE NONTRICYCLIC ANTIDEPRESSANT NEFAZODONE TO A REACTIVE QUINONE-IMINE SPECIES IN HUMAN LIVER MICROSOMES AND RECOMBINANT CYTOCHROME P450 3A4
TLDR
Findings are consistent with the proposal that two-electron oxidation of p-hydroxybuspirone to the corresponding quinone-imine is less favorable due to differences in the protonation state at physiological pH and due to weaker resonance stabilization of the oxidation products as predicted from ab initio measurements.
Metabolism of sertindole: identification of the metabolites in the rat and dog, and species comparison of liver microsomal metabolism.
TLDR
The findings suggest that the metabolism of sertindole in man resembles those in the rat and monkey and is different from that in the dog.

Hepatic microsomal metabolism and macromolecular binding of the antioxidant, N-phenyl-2-naphthylamine.
TLDR
There was a time-dependent linear increase in covalent binding of P2NA to microsomal protein and the extent of binding approximately paralleled the rate of metabolism, and macromolecular binding of this aromatic amine appears to occur without an obligatory N-dephenylation and may be due to the metabolic formation of epoxides.

TLDR
The coplanar 3,3',4,4'-tetrachlorobiphenyl (TCB) was given orally to mice and the metabolite patterns in feces, urine, liver, and adipose tissue were examined, indicating the presence of TCB metabolites with lipid characteristics.

TLDR
These microsomes contain a dexamethasone-inducible, NADPH-dependent factor, maybe cytochrome P-450 p (P450 IIIA1), which is especially effective in reductive dehalogenation of the fluoroanilines.

TLDR
The metabolic hydroxylation of ICI 54,450 has been reproduced in part by treatment with pertrifiuoracetic acid and it is shown that this agent undergoes metabolism in rats and dogs involving NIH shift migration of the chioro substituent.
A novel mechanism for the NIH-shift.
TLDR
This new mechanism for the NIH-Shift serves as a model for the ease of nucleophilic addition to other arene oxides, such as those of the polycyclic aromatic hydrocarbons recently implicated in mechanisms of carcinogenesis.
