title: Aminopyrine-N-demethylase. I. Directed modification of substrates' structure as a way of production of inducer of the monooxygenase isoform P-450b.
abstract: The effect of the phenobarbital-type monooxygenase inducers is accomplished via the native molecule. This made it possible to transform the typical substrate of cytochrome P-450b aminopyrine into an inducer of this isozyme by blocking the substrate molecule position undergoing monooxygenation. Substitution of two methyl groups in the aminopyrine -N(CH3)2 position by an isopropyl group gave rise to a clear-cut inducive effect. This was registered by spectral, kinetic, radiological and immunochemical methods.
