Abstract

Cette invention se rapporte à un procédé permettant de découvrir le site d'action de composés xénobiotiques. Ce procédé consiste à soumettre une cellule détecteur comprenant un promoteur sensible aux agents génotoxiques liés opérationnellement à un complexe de gènes reporteurs luminescents. L'exposition des bactéries détecteurs à des composés qui sont génotoxiques produit un accroîssement de la luminescence. Ces composés sont groupés et peuvent être analysés pour que leur activité pharmaceutique soit déterminée. L'exposition des bactéries détecteurs à des agents xénobiotiques actifs qui ne sont pas génotoxiques produit une inhibition de la bioluminescence ou de la luminescence stable. En soumettant les bactéries détecteurs à un tri, tel qu'un titrage génétique ou d'inversion nutritionnelle, on dévoile le site d'action du composé en question.
