Quinazoline-urea, new protein kinase inhibitors in treatment of prostate cancer

Abstract

Epidermal growth factor receptor (EGFR) and vascular endothelial growth factor receptor-2 (VEGFR-2), two protein tyrosine kinases, are involved in pathological disorders and the progression of different types of carcinomas. Concomitant inhibition of both tyrosine kinase activities appears to be an attractive target for cancer chemotherapy. A series of new quinazoline derivatives substituted by amide, urea, or carbamic acid ester groups have been synthesized. The biological activities of these new compounds have been evaluated for their enzyme inhibition and antiproliferative activities. © 2010 Informa UK Ltd.
