C-Jun NH2 terminal kinases (JNKs) are important cell signaling enzymes. JNK1 plays a central role in linking obesity and insulin resistance. JNK2 and JNK3 may be involved in inflammatory and neurological disorders, respectively. Small-molecule JNK inhibitors could be valuable tools to study the therapeutic benefits of inhibiting these enzymes and as leads for potential drugs targeting JNKs. In this report, we disclose a series of potent and highly selective JNK inhibitors with good pharmacokinetic profiles.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB code is shown on the right.
