Tetra-substituted imidazoles were designed as dualinhibitors of c-JunN-terminalkinase (JNK) 3 and p38αmitogen-activatedprotein (MAP) kinase. 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. Dualinhibitors with IC50 values down to the low double-digit nanomolar range at both enzymes were identified

We prepared novel 1,2,4,5-tetrasubstituted imidazole derivatives with high anti-inflammatory activity by using our previously described regiospecific synthesis. Systematic optimization of the imidazole N-1 substituent resulted in compound 9b that potently inhibited the mitogen-activated protein kinase p38 (p38 IC50 = 0.218 muM) as well as the release of the proinflammatory cytokines interleukin-1beta (IL-1beta) and tumor necrosis factor alpha. (TNFalpha) from human whole blood after stimulation with LPS. Furthermore, compound 9b exhibited reduced cytochrome P450 interaction in comparison with SB203580. This result is particularly important, since cytochrome P450 interaction is observed for some p38 inhibitors and in turn can potentially cause drug-drug interaction or lead to other hepatic changes such as P450 enzyme induction.

A novel and convenient method for the synthesis of a wide range of polyfunctional imidazolederivatives based on the three-component condensation of imidazole N-oxides with CH-acids and arylglyoxals has been developed. This reaction proceeds smoothly in moderate-to-good yields with a wide range of starting materials.
