CA 2353557

The present invention relates generally to the fields of bacteriology and mycology. More particularly, the present invention provides novel inhibitors of multidrug transport proteins that may be used in combination with existing antibacterial agent and/or antifungal agents to increase the toxic effects of the antimicrobial agents. More specifically, the present invention provides methods and compositions for enhancing the antibacterial action of fluoroquinolones by administering fluoroquinolones in combination with an inhibitor of multidrug transporters and of echancing the antifungal action of azole antifungal agents by administering an azole antifungal agent in combination with an inhibitor of multidrug transporters. Compositions comprising indole, urea, quinoline or aromatic amide based inhibitors also are disclosed.

De façon générale, la présente invention concerne les domaines de la bactériologie et de la mycologie. Plus précisément, elle s'applique à de nouveaux inhibiteurs de protéines transporteuses de plusieurs médicaments qui peuvent s'utiliser conjointement avec un agent antibactérien existant et/ou des antifongiques dans le but d'accroître les effets toxiques d'agents antimicrobiens. Spécifiquement, cette invention concerne des méthodes et des compositions destinées à accentuer l'action antibactérienne des fluoroquinolones. La démarche consiste à administrer des fluoroquinolones en combinaison avec un inhibiteur des protéines transporteuses multi-médicaments et à favoriser l'action des agents antifongiques de type azole par administration d'un tel agent en combinaison avec un inhibiteur de protéines transporteuses de plusieurs médicaments. L'invention concerne également des compositions comprenant des inhibiteurs à base d'indole, d'urée, de quinoline ou d'amides aromatiques.
