Half-maximal inhibitory concentration (IC₅₀) analysis on Hep3B and HepJ5 cells treated with TCEE alone or in combination with cisplatin or doxorubicin. The IC₅₀ values of TCEE on Hep3B and HepJ5 were analyzed on cell viability data obtained from Figure 1 by using the CalcuSyn software, and the IC₅₀ values of cisplatin and doxorubicin with TCEE were from Figure 3.

	Hep3B		HepJ5
TCEE (mg/mL)	0.48		0.91
Combined treatment with conventional chemotherapy agents
	TCEE (mg/mL)
	0	0.2	0	0.5
Cisplatin (μM)	5.38	2.29	4.57	2.82
Doxorubicin (μM)	2.37	0.91	1.28	0.51
