• PubMed Abstract: 
  

  The lead optimization of a series of potent azaindole IKK2 inhibitors is described. Optimization of the human whole blood activity and selectivity over IKK1 in parallel led to the discovery of 16, a potent and selective IKK2 inhibitor showing good efficacy in a rat model of neutrophil activation.
