32 results about "C-Jun N-terminal kinases" patented technology

The present invention relates to compounds that are inhibitors of c-jun N-terminal kinase 1, 2, or 3 (JNK1, JNK2, or JNK3), compositions containing the compounds and the use of the compounds in the prevention or treatment of disorders regulated by the activation of JNK1, JNK2 and JNK3.

Methods of reducing Wallerian degeneration are disclosed. These methods comprise inhibiting expression or activity of a mixed lineage kinase such as a dual leucine-zipper-bearing kinase (DLK), inhibiting expression or activity of a molecule acting downstream from DLK, such as a c-Jun N-terminal kinase (JNK), or a combination thereof. Further disclosed are methods of screening candidate compounds for DLK inhibition activity. These methods comprise providing a neuronal culture comprising a plurality of axons; contacting the culture with a candidate compound and with an axon degeneration-triggering agent; and comparing axonal degeneration in the culture to a control culture comprising the axon degeneration-triggering agent but not the candidate compound.

The intravitreal administration of a JNK-inhibiting peptide which comprises (a) at least either one of the JNK-inhibiting sequences depicted in SEQ ID NO:1 and SEQ ID NO:2 and (b) at least either one of the transfer sequences depicted in SEQ ID NO:3 and SEQ ID NO:4 and has a length shorter than 150 amino acid residues wherein at least one amino acid residue is a D-amino acid residue can prevent the occurrence of spermidine-induced damage of retinal pigment epitheliums, tunicamycin-induced visual cell injury, and laser-induced choroidal neovascularization. Therefore, the JNK-inhibiting peptide is useful for the prevention or treatment of retinal diseases. By using the JNK-inhibiting peptide, it becomes possible to provide a medicinal agent and a method both of which can prevent or treat retinal diseases through topical administration in eyes. It also becomes possible to provide use of the JNK-inhibiting peptide for the production of the medicinal agent.

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.
