The effects of trolox, vitamin E or vitamin C on curcumin-induced cytotoxicity of ovarian cancer cells.

	Curcumin	+Trolox		+ Vit E		+Vit C
		10 μM	100 μM	10 μM	100 μM	10 μM	100 μM
IC50, (μM)	5.44	0.58	0.31	3.75	2.10	1.5	0.75

A2780 cells were treated with curcumin at increasing concentrations in the presence or absence of 10-100 μM trolox, vitamin E or vitamin C for 72 hours.

Cell viability was analyzed using the MTS assay.

IC₅₀ (μM) values were calculated through nonlinear regression using the one site competition curve (n=3).
