Synthesis and SAR of 1,9-dihydro-9-hydroxypyrazolo[3,4-b]quinolin-4-ones as novel, selective c-Jun N-terminal kinase inhibitors
Bioorg. Med. Chem. Lett. (2006) 16 p.2590-2594
A novel class of 1,9-dihydro-9-hydroxypyrazolo[3,4-b]quinolin-4-ones as c-Jun-N-terminal kinase (JNK) inhibitors is described. These compounds were synthesized via the condensation of 2-nitrobenzaldehydes and hydroxypyrazoles. The structure-activity relationships (SAR) and kinase selectivity profile of the inhibitors are also discussed. Compound 16 was identified as a potent JNK inhibitor with good cellular potency.
