The intracellular gold concentration levels caused by the incubation of [Au(kin)(PPh3)] (1), [Au(PPh3)Cl], and Auranofin with A2780 cells after 2 h, 6 h, 12 h, 24 h, 48 h, and 72 h. The results were obtained by ICP-MS analyses of three parallel samples and are shown as mean values with error bars corresponding to the standard deviation values of the gold concentration expressed in ng of gold per 106 cells.
