Table 4. In Vitro Cytotoxic Activities of Lipo-Eucam^a.

	in vitro cytotoxic activity (IC50 in μg/mL)			SIb
samples	MCF-7	MDA-MB-231	HEK-293	MCF-7	MDA-MB-231
Lipo-Eucam	7.34 ± 0.51	13.86 ± 0.89	>80	>10.9	5.77
DOX	0.45 ± 0.01	0.23 ± 0.01	0.31 ± 0.03	0.67	1.35

^aThe treatment period was 72 h. Data represent the mean ± standard deviation of triplicate.

^bThe SI was obtained as the average of the IC₅₀ value of the normal HEK-293 cell line divided by the IC₅₀ value of the cancer cell line in obtained in each independent experiment.
