• PubMed Abstract: 
  

  Pyrazolopyrimidines are well-established as covalent inhibitors of protein kinases such as the epidermal growth factor receptor or Bruton's tyrosine kinase, and we recently described their potential in targeting mitogen-activated protein kinase kinase 7 (MKK7). Herein, we report the structure-activity relationship of pyrazolopyrimidine-based MKK7 inhibitors and solved several complex crystal structures to gain insights into their binding mode. In addition, we present two structures of apo-MKK7, exhibiting a DFG-out and an unprecedented DFG-in/Leu-in conformation.
