Vascular endothelial growth factor receptor-2 (VEGFR-2) kinase inhibition is a well-established strategy to promptly tackle tumor growth by suppression of angiogenesis. We report herein a series of 5-anilinoquinazoline derivatives substituted by 1,3-disubstituted urea. All the newly synthesized compounds described were evaluated for VEGFR-2 kinase inhibition and antiproliferative activity against various cancer cells. The novel 1-aryl, 3-aryl-disubstituted urea quinazolines were effective VEGFR-2 kinase inhibitors with in vitro IC50 values in the submicromolar range (compound 6f, IC50 12.0 nM), but showed a weak to moderate inhibitory activity on cancer cells. Molecular interactions of the compounds were studied using molecular docking studies.
