A simple and efficient procedure for the synthesis of 2-hydroxy-2-(5-hydroxy-1H-pyrazol-4-yl)-2H-indene-1,3-dione derivatives, proceeding via aldolcondensation between ninhydrin and various 3-alkyl-1H-pyrazol-5-ols is described. The syntheses were carried out in ethanol at room temperature and proceeded with short reaction times to give the products with high yields.

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.
