VEGFR-2, EGFR ve PDGFR-β tyrosine kinases inhibitory activities of the tested compounds were determined using KDR Kinase Enzyme System Analysis Kit (Promega, #V2681), EGFR Kinase Enzyme System Analysis Kit (Promega, #V3831) and PDGFR-β Kinase Enzyme System Analysis Kits (Promega, #V3731) according to the manufacturer’s instructions. The molecular docking studies were performed using Autodock vina program. Compounds 9a, 9b and 11b exhibited the weak inhibitory activities against VEGFR-2, EGFR and PDGFR-β, respectively. Molecular docking studies showed that one or two hydrogen bonding interactions were found between compounds 9a, 9b, 11b and VEGFR-2, EGFR, PDGFR-β tyrosine kinases. Biological activity and molecular docking results revealed that interactions of compounds with target protein active sites are not enough to obtain potent RTK inhibitory activity. It is necessary to design some compounds showing more interactions with the target proteins to obtain better activity results.
