Abstract
The synthesis and structure-activity relationships of novel 4-(4â²-fluorophenyl)imidazoles as selective p38α MAPK, CK1δ and JAK2 inhibitors with improved water solubility are described. Microwave-assisted multicomponent reactions afforded 4-fluorophenyl-2,5-disubstituted imidazoles. Carboxylate and phosphonate groups were introduced via 'click' reactions. The kinase selectivity was influenced by the heteroaryl group at imidazole C-5 and the position of a carboxylic acid or tetrazole at imidazole C-2. For example, pyrimidines 15 and 34 inhibited p38α MAPK with IC50 = 250 nM and 96 nM, respectively. Pyridine 3 gave CK1δ inhibition with IC50 = 89 nM and pyridin-2-one 31 gave JAK2 inhibition with IC50 = 62 nM.
