Abstract: | p38alpha Mitogen Activated Protein Kinase (MAP kinase) is an intracellular soluble serine threonine kinase. p38alpha kinase is activated in response to cellular stresses, growth factors and cytokines such as interleukin-1 (IL-1) and tumor necrosis factor alpha (TNF-alpha). The central role of p38alpha activation in settings of both chronic and acute inflammation has led efforts to find inhibitors of this enzyme as possible therapies for diseases such as rheumatoid arthritis, where p38alpha activation is thought to play a causal role. Herein, we report structure-activity relationship studies on a series of indole-based heterocyclic inhibitors that led to the design and identification of a new class of p38alpha inhibitors. |
