  • PubMed Abstract: 

    The design, synthesis, and structure-activity relationships (SAR) of a series of 2-aminothiazol-5-yl-pyrimidines as novel p38α MAP kinase inhibitors are described. These efforts led to the identification of 41 as a potent p38α inhibitor that utilizes a unique nitrogen-sulfur intramolecular nonbonding interaction to stabilize the conformation required for binding to the p38α active site. X-ray crystallographic studies that confirm the proposed binding mode of this class of inhibitors in p38 α and provide evidence for the proposed intramolecular nitrogen-sulfur interaction are discussed.
