MTT assay to determine the IC 50 value of the different drugs and analyze their effect on cell viability. The different drug concentrations used and the corresponding cell viability graphs are shown for AZA (A), TSA (B), SFN (C), and SAM (D). The IC50 value (that is, the concentration of drug which exhibited 50% cell viability for MCF-7 and MDA-MB-231 cells) were 15, 15, 10 μM, and 100 nM, respectively, for AZA, SAM, SFN, and TSA, respectively.
