Efficient Synthesis and Biological Activity of Novel Indole Derivatives as VEGFR-2 Tyrosine Kinase Inhibitors

摘要

A series of novel indole derivatives were synthesized as potent inhibitors for the vascular endothelial growth factor receptor 2 (VEGFR-2) tyrosine kinase. Among those, compound 10b demonstrated the highest growth inhibition rate of 66.7% against the VEGFR-2 tyrosine kinase at 10 mu M which indicates that indole-benzothiazole might be the favorable structure. The binding mode of compound 10b with VEGFR-2 tyrosine kinase was evaluated by molecular docking.
