Abstact

p38alpha MAP kinase is a key anti-inflammatory target for rheumatoid arthritis, influencing biosynthesis of pro-inflammatory cytokines TNFalpha and IL-1beta at a translational and transcriptional level. In this paper, we describe how we have optimized a series of novel p38alpha/beta inhibitors using crystal structures of our inhibitors bound to p38alpha, classical medicinal chemistry, and modeling of virtual libraries to derive a molecule suitable for progression into clinical development.
