In vitro cytotoxicity of amantadine, ribavirin and pleconaril in HCT8WT/RETO cells. Cytotoxicity was measured over 24 hours by MTT assay. Amantadine and pleconaril show a specific activity in the highly chemotherapy-resistant subline. Values represent the means ± standard deviation of at least n = 3 independent experiments
