Comparing compounds 15 and 18 to sorafenib, the in vitro VEGFR-2 inhibitory activity displayed encouraging selective efficacy with IC50 values of 13, 67, and 30 nM, respectively. Results of VEGFR-2 inhibition at various ATP concentrations proved that there was no statistically significant difference between the IC50 values, which
