A375, human metastatic melanoma cell line; MDA-MB-231, human breast cancer cell line; NA, no activity; IC50, 50% inhibitory concentration; SD, standard deviation of mean, IC50 values of compound were evaluated using GraphPad Prism 7 software. Data represent the mean ± standard deviations of three replicates (n=3). R-squared is a statistical measure of how close the data are to the fitted regression line in graph.
