The Sulforhodamine B (SRB) cytotoxicity assay of the tested 8b as compared to drug-optimized SLNs formula (F8) on MDA-MB-231/breast cancer cells. At 5 × 103 cells/well cell density, cells were treated with various 8b concentrations (0.01, 0.1, 1, 10, and 100 µM) for 72 h exposure time frame. Cytotoxic effect was detected via protein-bound SRB colorimetric assay (540 nm) and % cell growth viability was estimated in triplicates as compared to vehicle negative controls representing the untreated cells.
