- The activation of c-Jun N-terminal kinases (JNKs) plays an important role in physiological processes including neuronal function, immune activity, and development, and thus, JNKs have been a therapeutic target for various diseases such as neurodegenerative diseases, inflammation, and cancer. Efforts to develop JNK-specific inhibitors have been ongoing for several decades. In this process, the structures of JNK in complex with various inhibitors have contributed greatly to the design of novel compounds and to the elucidation of structure-activity relationships. Almost 100 JNK structures with various compounds have been determined. Here we summarize the information gained from these structures and classify the inhibitors into several groups based on the binding mode. These groups include inhibitors in the open conformation and closed conformation of the gatekeeper residue, non-ATP site binders, peptides, covalent inhibitors, and type II kinase inhibitors. Through this work, deep insight into the interaction of inhibitors with JNKs can be gained and this will be helpful for developing novel, potent, and selective inhibitors. (C) 2020 The Author(s).
