Quantitative structure-toxicity relationships by accelerated cytotoxicity mechanism screening.

This article focuses on the application of quantitative structure-activity relationships (QSARs) and quantitative structure-toxicity relationships (QSTRs) to metabolic pathways that can induce cytotoxicity. The different methods for carrying out QSAR studies are reviewed, with their advantages and disadvantages being outlined. Furthermore, we propose a novel approach for linking metabolism to toxicity and for using QSTRs to evaluate these effects. This approach could provide a more complete evaluation of new chemical entities for drug discovery or xenobiotic cytotoxicity mechanism screening.
