Abstract: Novel purine compounds and tautomers and pharmaceutically acceptable salts thereof are described, as are pharmaceutical compositions comprising the same, complexes comprising the same, e.g., HSP90 complexes, and methods of using the same.

Abstract: The present invention is related to sulfonamide derivatives having a lipophilic moiety and which are substantially soluble. Said compounds are notably for use as pharmaceutically active compounds. The present invention also related to pharmaceutical formulations containing such sulfonamide derivatives. Said sulfonamide derivatives are efficient modulators of the JNK pathway, they are in particular efficient and selective inhibitors of JNK 2 and 3. The present invention is furthermore related to novel sulfonamide derivatives as well as to methods of their preparation.

Abstract: The present invention is related to substantially hydrophilic sulfonamide derivatives, or sulfonamide derivatives having a substantially hydrophilic moiety, of formula I notably for use as pharmaceutically active compounds, as well as to pharmaceutical formulations containing such sulfonamide derivatives. Said sulfonamide derivatives are efficient modulators of the JNK pathway, they are in particular efficient and selective inhibitors of JNK 3. The present invention is furthermore related to novel sulfonamide derivatives as well as to methods of their preparation.

Abstract: 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.
