ND indicates no IC50 values were obtained since no significant antiproliferative/cytotoxic activity was found in this tested concentration range. Data is shown as the mean ± 1 SE from three independent repeats after a 72 h exposure to the test compound. Means (within and between columns) with a different lowercase superscript letter are significantly different (p ≤ 0.05; Kruskal-Wallis test)
