    A novel series of p38 MAP kinase inhibitors with high selectivity for the p38α isoform over the other family members including the highly homologous p38β isoform has been identified. X-ray co-crystallographic studies have revealed an unprecedented kinase binding mode in p38α for representative analogs, 5c and 9d, in which a Leu108/Met109 peptide flip occurs within the p38α hinge region. Based on these findings, a general strategy for the rational design of additional promising p38α isoform selective inhibitors by targeting this novel binding mode is proposed.
