- Thienopyrimidine and furan and pyrimidine derivatives, its preparation process and its use in medicine
-
Disclosed are thienopyrimidine and furopyrimidine derivatives, the preparation method thereof and the medical use thereof. The derivatives have a structure as shown in formula V. The thienopyrimidine and furopyrimidine derivatives provided in the present invention have dominant EGFR inhibiting activity, and some of these compounds also have dominant inhibiting activity against VEGFR; therefore, same can expect to be developed as tyrosine kinase EGFR and/or VEGFR inhibitors, and to be used for preparing the drugs for preventing or treating the diseases related to epidermal growth factor receptor EGFR and/or vascular endothelial growth factor receptor VEGFR. Provided is a new development direction and approach for developing novel tyrosine kinase inhibitor drugs having low drug resistance or able to relieve drug resistance to the inhibitor in the early stages, thereby having extensive application prospects and medical value.
