Abstract

Aim: Simultaneous inhibition of VEGFR2/KDR/Flk-1 and Src may enhance the efficacy of VEGFR2-targeted Cancer therapeutics. Hence, development of dual inhibitors on VEGFR2/KDR/Flk-1 and Src can be a useful strategy for such treatments.

Materials & methods: A multistep virtual screening protocol, comprising ligand-based support vector machines method, drug-likeness rules filter and structure-based molecular docking, was developed and employed to identify dual inhibitors of VEGFR2/KDR/Flk-1 and Src from a large commercial chemical library. Kinase inhibitory assays and cell viability assays were then used for experimental validation.

Results: A set of compounds belonging to six different molecular scaffolds was identified and sent for biological evaluation. Compound 3c belonging to the 2-amino-3-cyanopyridine scaffold exhibited good antiproliferative effect and dual-target activities against VEGFR2/KDR/Flk-1 and Src.

Conclusion: This study demonstrated the ability of the multistep virtual screening approach to identify novel multitarget agents.
