Synthesis and SAR of 1,9-dihydro-9-hydroxypyrazolo[3,4-b]quinolin-4-ones as novel, selective c-Jun N-terminal kinase inhibitors.
M.Liu, Z.Xin, J.E.Clampit, S.Wang, R.J.Gum, D.L.Haasch, J.M.Trevillyan, C.Abad-Zapatero, E.H.Fry, H.L.Sham, G.Liu.
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.

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.
