Abstract
As a continuation of our work with 1,4,5 substituted imidazole inhibitors of p38alpha, we report a series of 1-(4-piperidinyl)-4-(4-fluorophenyl)-5-(2-phenoxy-4-pyrimidinyl) imidazoles related to 7. The compounds have IC50's for inhibition of p38alpha ranging from 6.0 to 650nM. Statistical analysis of the p38beta inhibitor potencies shows a correlation of IC50's with the electron donating strength of low molecular weight substituents.
