• PubMed Abstract: 
  

  Optimization of our bis-anilino-pyrimidine series of EphB4 kinase inhibitors led to the discovery of compound 12 which incorporates a key m-hydroxymethylene group on the C4 aniline. 12 displays a good kinase selectivity profile, good physical properties and pharmacokinetic parameters, suggesting it is a suitable candidate to investigate the therapeutic potential of EphB4 kinase inhibitors.
