We report the design and discovery of a 2-aminobenzimidazole-based series of potent and highly selective p38alphainhibitors. The lead compound 1 had low-nanomolar activity in both ATP competitive enzyme binding and inhibition of TNFalpha release in macrophages. Compound 18 showed excellent pharmacokinetics properties and oral activity in the rat collagen induced arthritis model compared with other
我们报告了基于
