title: [Mechanisms of the phenazepam oxidation reactions in cell membranes].
abstract: During phenazepam oxidation by rat, mouse and rabbit liver microsomes, the maximal amount of products was formed if NADP-H was used as electron donor. Addition of equimolar concentration of NAD-H did not stimulate phenazepam oxidation. The monooxygenase inhibitor, SKF-525A, reduced the rate of phenazepam oxidation depending on the type of experimental animals. The mechanisms of enzymatic formation from phenazepam of 3-hydroxymetabolite, quinazoline and aromatic hydroxylation products are discussed.
