Cytotoxic effects of PyED and the enhancement of PyED cytotoxicity by hyperthermia. U-1 melanoma cells were treated with various concentrations of PyED or 1.5% DMSO (0 μM PyED) for 1h at either 37 or 42.5 °C. Surviving fractions were normalized to the samples treated with DMSO (vehicle) at each of the respective temperatures. The plating efficiencies for cells treated with DMSO only at 37 or 42.5° C were 0.74 or 0.16, respectively. Error bars represent the SEM for two to four experiments.
