Half maximal inhibitory concentration (IC50) of PSS and PL determination on 4 breast cancer cell lines, 72-h post-exposure by MTT assay. Cisplatin was used as a positive control. Cell viability was calculated and reported as dose-inhibitory curve. IC50 was generated by GraphPad Prism 8 software. A, E, and I MCF7, B, F, and J T47D, C, G, and K MDA-MB-231, and D, H, and L MDA-MB-468 cell line. The experiment was performed for 5 independent replicates, data represented as mean ± SE
