Starting from an initial HTS screening lead, a novel series of C(5)-substituted diaryl pyrazoles were developed that showed potent inhibition of p38 alpha kinase. Key to this outcome was the switch from a pyridyl to pyrimidine at the C(4)-position leading to analogs that were potent in human whole blood based cell assay as well as in a number of animal efficacy models for rheumatoid arthritis. Ultimately, we identified a clinical candidate from this substrate; SD-0006. (C) 2010 Elsevier Ltd. All rights reserved.
