MoleculeDescription

Molfile Inchi Smiles

Synonyms:

  • ZD1839
  • gefitinib
  • iressa
  • ZD 1839
Gefitinib reversibly inhibits the kinase activity of wild-type and certain activating mutations of EGFR, preventing autophosphorylation of tyrosine residues associated with the receptor, thereby inhibiting further downstream signalling and blocking EGFR-dependent proliferation.
