CA 2452259

The present invention relates to sulfonamide derivatives of formula (I) notably for use as pharmaceutically active compounds, as well as to pharmaceutical formulations containing such sulfonamide derivatives. Said sulfonamide derivatives are useful in the treatment of neuronal disorders, autoimmune diseases, cancer and cardiovascular diseases. Furthermore, said sulfonamide derivatives are efficient modulators of the JNK pathway, they are in particular efficient and selective inhibitors of JNK2 and -3. The present invention is furthermore related to novel sulfonamide derivatives as well as to methods of their preparation. Formula (I) IAr1 is a substituted or unsubstituted aryl or heteroaryl group; X is O or S, preferably O; Ar2 a substituted or unsubstituted arylene or heteroarylene group;R1 and R2 are independently selected from the group consisting of hydrogen and a C1-C6-alkyl group.

L'invention a trait à des dérivés de sulfonamide représentés par la formule (I), utiles notamment comme composés pharmaceutiquement actifs, et à des formulations pharmaceutiques contenant ces dérivés de sulfonamide. Ces dérivés sont utiles dans le traitement de troubles neuronaux, de maladies auto-immunes, du cancer et de maladies cardio-vasculaires. De plus, ils constituent des modulateurs efficaces de la voie JNK, et notamment des inhibiteurs sélectifs et efficaces de JNK2 et JNK3. L'invention concerne en outre de nouveaux dérivés de sulfonamide ainsi que des procédés de préparation de ceux-ci. Dans la formule (I) Ar?1¿ représente un groupe aryle ou hétéroaryle substitué ou non substitué ; X représente O ou S, de préférence O ; Ar?2¿ représente un groupe arylène ou hétéroarylène substitué ou non substitué ; R?1¿ et R?2¿ sont sélectionnés indépendamment dans le groupe constitué par hydrogène et un groupe alkyle en C¿1?-C¿6?.
