Patent

CA 2489428

The invention describes novel cyclooxygenase 2 (COX-2) selective inhibitors and novel compositions comprising at least one cyclooxygenase 2 (COX-2) selective inhibitor, and, optionally, at least one compound that donates, transfers or releases nitric oxide, stimulates endogenous synthesis of nitric oxide, elevates endogenous levels of endothelium-derived relaxing factor or is a substrate for nitric oxide synthase, and/or at least one therapeutic agent. The invention also provides novel kits comprising at least one COX-2 selective inhibitor, optionally nitrosated and/or nitrosylated, and, optionally, at least one nitric oxide donor, and/or, optionally, at least one therapeutic agent. The novel cyclooxygenase 2 selective inhibitors of the invention can be optionally nitrosated and/or nitrosylated. The invention also provides methods for treating inflammation, pain and fever; for treating and/or improving the gastrointestinal properties of COX-2 selective inhibitors; for facilitating wound healing; for treating and/or preventing renal and/or respiratory toxicity; for treating and/or preventing other disorders resulting from elevated levels of cyclooxygenase-2; and for improving the cardiovascular profile of COX-2 selective inhibitors.

L'invention concerne des inhibiteurs sélectifs de la cyclooxygénase 2 (COX-2) et des compositions contenant au moins un inhibiteur sélectif de la cyclooxygénase 2 (COX-2), et, éventuellement, au moins un composé qui donne, transfère ou libère du monoxyde d'azote, stimule la synthèse endogène du monoxyde d'azote, élève les taux endogènes du facteur relaxant d'origine endothéliale ou constitue un substrat pour la synthase de monoxyde d'azote et/ou au moins un agent thérapeutique. L'invention concerne également des trousses comprenant au moins un inhibiteur sélectif de COX-2, éventuellement nitrosé et/ou nitrosylé, et, éventuellement, au moins un donneur de monoxyde d'azote et/ou, éventuellement, au moins un agent thérapeutique. Les inhibiteurs sélectifs de la cyclooxygénase 2 selon l'invention peuvent être éventuellement nitrosés et/ou nitrosylés. L'invention concerne également des méthodes permettant de traiter l'inflammation, la douleur et la fièvre ; de traiter et/ou d'améliorer les propriétés gastro-intestinales des inhibiteurs sélectifs de COX-2 ; de faciliter la cicatrisation des blessures ; de traiter et/ou de prévenir la toxicité rénale et/ou respiratoire ; de traiter et/ou de prévenir d'autres troubles dus aux taux élevés de cyclooxygénase-2 ; et d'améliorer le profil cardiovasculaire des inhibiteurs sélectifs de COX-2.
