Abstract: L'invention concerne de nouveaux composés substrats qui inhibent de manière sélective la prolifération de cellules pathologiques, par exemple, de cellules pathologiques qui surexpriment de manière endogène un enzyme cible qui confère une bonne résistance aux agents biologiques et chimiothérapeutiques. L'enzyme agit sur un composé substrat de manière 1) à le convertir en une toxine cellulaire et/ou 2) à libérer un sous-produit toxique. Dans un mode de réalisation, l'activité de l'enzyme cible a été considérablement améliorée dans une cellule cible en raison de la perte de la fonction de suppression des tumeurs et/ou de la sélection résultant d'une exposition préalable à un traitement chimiothérapeutique. Dans un autre mode de réalisation, la cellule pathologique contient un enzyme cible qui est un produit d'expression d'un agent infectieux dans la cellule. L'invention concerne également une méthode de traitement qui consiste à administrer à un patient un promédicament tel que décrit par l'invention. Les promédicaments selon l'invention peuvent être utilisés seuls ou combinés à d'autres thérapies chimiothérapeutiques ou à d'autres thérapies contre le cancer telles que la radiothérapie.
