found as the most potent antiproliferative, had the highest inhibitory effect on EGFR with an IC50 value of 90 nM, compared to erlotinib’s IC50 value of 70 nM. The second and third-most active compounds were 4e (R = phenyl, n = 3) and 4d (R = ethyl, n = 3) and with IC50 values of 107 nM and 128 nM. These findings imply that the compounds tested had a significant antiproliferative effect as well as the
