• PubMed Abstract: 
  

  A novel structural class of p38alpha MAP kinase inhibitors has been identified via iterative SAR studies of a focused deck screen hit. Optimization of the lead series generated 6e, BMS-640994, a potent and selective p38alpha inhibitor that is orally efficacious in rodent models of acute and chronic inflammation.
