The cytotoxicity of KTt-45 on different cell lines. (A) The correlation between KTt-45 concentrations and percentage growth inhibition (I%) towards cell lines after 48 h treatment. Each dot represents mean ± SD (A549, MCF7, BJ-5ta, n = 3; HeLa, Raji, n = 4). (B) The changes in cell morphology of different cell lines induced by KTt-45 after 48 h treatment. The scale bars indicate 50 μm.
