Previously we reported the identification of RPR200765A, a potent orally bioavailable pyridine-imidazole inhibitor of p38 mitogen-activated protein (MAP) kinase which suppressed paw swelling and joint pathology in streptococcal cell wall-induced arthritis. Herein, we report the use of solid-phase combinatorial organic synthesis for the parallel processing of a related pyrimidine-imidazole-based library with two points of structural ...
