Erlotinib, nelfinavir and nitroxoline affect cell viability in AsPC-1, Capan-2 and BxPC-3. Cell viability was assessed by MTT assay after incubation for 48 h with erlotinib (a) nelfinavir (b) or nitroxoline (c) at the indicated concentrations, or with vehicle (control). Data shown are the means ± SD of three independent experiments with quintuplicate determinations. *Statistically significant differences between control and each drug concentration (*p < 0.05; **p < 0.01; ***p < 0.001; ****p < 0.0001)
