Furthermore, the compound induced a highly significant (P < 0.0001) antiproliferative effect at 72 vs. 96h exposure period (concentration range 31.25–250 μM in MDA-MB-231 and 15.62–125 μM in MDA-MB-468 cell line) as indicated by the significant reduction in the IC 50 values, in particular for MDA-MB-468 cells.
