The IC50 values for HepG2 and THLE-2 cell lines.

	HepG2		THLE-2
	IC50	±SEM	IC50	±SEM
I3C	N/A		N/A
X	34.2	2.3	37.0	3.0
PEITC	31.0	2.0	38.0	2.0
RES	N/A		N/A
X + I3C	30.2	0.6	40.7	1.0
X + PEITC	26.5	1.6	37.5	1.2
X + RES	38.5	5.5	42.0	0.8
I3C + PEITC	32.2	1.0	44.5	0.8
I3C + RES	N/A		48.5	0.5
RES + PEITC	63.8	2.0	39.5	0.3

The IC50 values (n = 3) ±SEM (µM) were calculated based on the dose-response curves assessed by the MTT assay.
