3,5-Disubstituted quinolines as novel c-Jun N-terminal kinase inhibitors

The structure-based design and synthesis of a novel series of c-Jun N-terminal kinase (JNK) inhibitors with selectivity against p38 is reported. The unique structure of 3,5-disubstituted quinolines (2) was developed from the previously reported 4-(2,7-phenanthrolin-9-yl)phenol (1). The X-ray crystal structure of 16a in JNK3 reveals an unexpected binding mode for this new scaffold with protein.
