Abstract :

The vascular endothelial growth factor receptor-2 (VEGFR-2) is considered as the most important transducer of VEGFdependent angiogenesis. VEGFR-2 is highly up-regulated in several solid tumors and plays a critical role in the process of tumor angiogenesis; therefore, VEGFR-2 inhibition emerged as a prime approach for discovering new therapies for many human angiogenesis-dependent malignancies. A novel series of indole derivatives was synthesized and tested for their cytotoxic activities against a panel of 60 cancer cell lines. A molecular docking study was also carried out to determine their binding modes and binding affinities in the VEGFR-2 active site using a reference VEGFR-2 inhibitor, sorafenib (Figure 1). The synthesized compounds exhibited a broad spectrum antiproliferative activity on 60 cell lines with growth inhibition percent (GI)% ranging from 31 to 82.5%. An indoloimidazolone derivative was found the most potent VEGFR-2 inhibitor with IC50 of 0.07 �µM more potent than that of sorafenib (0.09 �µM). The molecular docking study attributed the promising inhibitory activity on VEGFR-2 of this series to their hydrophobic interaction with the VEGFR-2 binding site hydrophobic side chains and their hydrogen bonding interaction with the key amino acids Glu885 and Asp1046.
