title: [Using distance comparison method to build pharmacophore model of epidermal growth factor receptor inhibitors].
abstract: OBJECTIVE
  To build 3D-pharmacophore model of epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors using distance comparisons method and design novel EGFR inhibitors.
  
  
  METHODS
  Thirteen typical EGFR inhibitors were selected, and their biologically active conformations were obtained by using DOCK5.0 program, then 3D-pharmacophore model of EGFR inhibitors was built using distance comparisons method.
  
  
  RESULTS
  Validation of the 3D-pharmacophore model was carried out and novel structures with potential inhibitory activity were selected by means of 3D-searching and docking method.
  
  
  CONCLUSIONS
  This method can improve hit rate of lead compounds discovery and can be used to design novel EGFR inhibitors.
