title: Interaction of a series of nitriles with the alcohol-inducible isoform of P450: computer analysis of structure-activity relationships.
abstract: 1. Structural studies are reported on a series of 20 nitriles of varying rates of P4502E-mediated oxidative metabolism. 2. Parameters of molecular and electronic structure have been calculated for the generation of quantitative structure-activity relationships (QSARs) with the rates of oxidative metabolism of the nitriles, and with their acute toxicity. 3. Correlations between molecular polarizability, excitation energy and biological activity are presented as a result of QSAR analysis.
