• PubMed Abstract: 
  

  Targeting acquired drug resistance represents the major challenge in the treatment of EGFR-driven non-small-cell lung cancer (NSCLC). Herein, we describe the structure-based design, synthesis, and biological evaluation of a novel class of covalent EGFR inhibitors that exhibit excellent inhibition of EGFR-mutant drug-resistant cells. Protein X-ray crystallography combined with detailed kinetic studies led to a deeper understanding of the mode of inhibition of EGFR-T790M and provided insight into the key principles for effective inhibition of the recently discovered tertiary mutation at EGFR-C797S.
