A library of 45 derivatives was prepared and evaluated in a kinase activity assay for their ability to inhibit both kinases, JNK3 and p38α MAP kinase. Dual inhibitors with IC<sub>50</sub> values down to the low double-digit nanomolar range at both enzymes were identified. The best balanced dual JNK3/p38α MAP kinase inhibitors are <b>6m</b> (IC<sub>50</sub>: JNK3, 18 nM; p38α, 30 nM) and <b>14d</b> (IC<sub>50</sub>: JNK3, 26 nM; p38α, 34 nM) featuring both excellent solubility and metabolic stability. They may serve as useful tool compounds for preclinical proof-of-principle studies in order to validate the synergistic role of both kinases in the progression of Huntington’s disease. p 38α MAP kinase;45 derivatives;Dual inhibitors;JNK 3;IC 50 values;Dual Inhibitors;nanomolar range;nM;Potential Treatment;tool compounds;kinase activity assay;6 m 2015-01-08
