Abstract

The invention discloses a selective inhibitor of a clinical mutant of EGFR protein tyrosine kinase, a diaromatic ring template compound containing thienopyrimidine having the structure shown in formulas (I and II) and a preparation method and application of the compound as the selective inhibitor of the clinical mutant of the EGFR protein tyrosine kinase. The selective inhibitor particularly has an inhibiting effect on an epidermal growth factor receptor EGFR of T790M mutation, and treats the diseases associated with the overexpression of the epidermal growth factor receptor EGFR such as the kidney cancer, the lung cancer, the prostate cancer, the pancreatic cancer, the breast cancer and glioma.

Description

technical field [0001] The present invention relates to thienopyrimidine bisaromatic ring derivatives. Background technique [0002] Epithelial growth factor EGFR (epithelial growth factor receptor) is a 170kDa transmembrane glycoprotein receptor tyrosine kinase, which is activated by epidermal growth factor and affects cell growth and differentiation. Binding of EGF or TGF[alpha] to EGFR activates the receptor's tyrosine kinase activity. The tyrosine residues Tyr1068, Tyr1148, and Tyr1173 at the carboxy-terminus of EGFR are the main sites for autophosphorylation following EGF binding. Once activated, phosphorylated tyrosine residues at positions 1068 and 1173 of EGFR mediate the binding of Grb2 to EGFR. In addition, the phosphorylated tyrosine residue at position 1173 is the main binding site of SHC on EGFR. EGFR is widely distributed in many normal and malignant epithelial cells, and its overexpression and self-activation may be related to the occurrence and development...
