Effect of s-cal14.1a on cell viability. Lung cancer cells H1299, H1437, H1975 and H661 were seeded on 96-well plates and treated with 27 μM of s-cal14.1a for 24 h. Cell viability was determined by measuring absorbance in wells at 490 nm with MTS assay. Results were normalized to untreated cells (C−) to obtain the percentage of cell viability and are expressed as the mean ± SEM. Positive control (C+) 5 μM of staurosporine. Experiments were done in triplicates. * p < 0.05, ** p < 0.01 and *** p < 0.001 vs. C− (unpaired t Student’s test).
