The present invention is related to benzsulfonamide derivatives of formula I notably for use as pharmaceutically active compounds, as well as to pharmaceutical formulations containing such benzsulfonamide derivatives. Said benzsulfonamide derivatives are ef-ficient modulators of the JNK pathway, they are in particular efficient and selective in-hibitors of JNK 2 and 3. The present invention is furthermore related to novel benzsul-fonamide derivatives as well as to methods of their preparation (I). The compounds of formula I according to the present invention being suitable pharma-ceutical agents are those wherein Ar1 is a substituted or unsubstituted aryl or heteroaryl group. X is O or S, preferably O.R1 is hydrogen or a C1-C6-alkyl group, preferably H.R2 is hydrogen, —COOR3, —CONR3R3′, OH, a C1-C4 alkyl substituted with an OH group, a hydrazido carbonyl group, a sulfate, a sulfonate, an amine or an ammonium salt; n is either 0 or 1, preferably 1.
本发明涉及公式I的苯磺酰胺衍生物,特别是作为药物活性化合物的用途,以及包含这种苯磺酰胺衍生物的制药配方。所述的苯磺酰胺衍生物是JNK途径的有效调节剂,特别是JNK 2和3的有效和选择性抑制剂。本发明还涉及新型苯磺酰胺衍生物以及其制备方法(I)。根据本发明的公式I化合物适合作为药物制剂的药剂学代理,其中Ar1是取代或未取代的芳基或杂环芳基基团。X是O或S,优选为O。R1是氢或C1-C6烷基,优选为H。R2是氢,-COOR3,-CONR3R3',OH,带有OH基团的C1-C4烷基,肼基羰基基团,硫酸盐,磺酸盐,胺或铵盐;n为0或1,优选为1。
