de novo Design and synthesis of N-benzylanilines as new candidates for VEGFR tyrosine kinase inhibitors

N-Benzylanilines were designed and synthesized as vascular endothelial growth factor (VEGF)-2 inhibitors using de novo drug design systems based on the X-ray structure of VEGFR-2 kinase domain. Among compounds synthesized, compound 3 showed the most potent inhibitory activity toward VEGFR-2 (KDR) tyrosinekinase and its IC50 value was 0.57 µM.
