  • PubMed Abstract: 

    A series of 1-aryl-3,4-dihydroisoquinoline inhibitors of JNK3 are described. Compounds 20 and 24 are the most potent inhibitors (pIC50 7.3 and 6.9, respectively in a radiometric filter binding assay), with 10- and 1000-fold selectivity over JNK2 and JNK1, respectively, and selectivity within the wider mitogen-activated protein kinase (MAPK) family against p38alpha and ERK2. X-ray crystallography of 16 reveals a highly unusual binding mode where an H-bond acceptor interaction with the hinge region is made by a chloro substituent.
