PA3264 significantly suppressed the viability of MDA-MB-231 cells. A MDA-MB-231 cells were treated with serial concentrations of PA3264, and the effects of PA3264 on cell proliferation were measured using the Cell Counting Kit-8 examinations at 24 h. B LDH was released from MDA-MB-231 cells after 24 h of treatment with different concentrations of PA3264. C–D Images and results of colony formation assay with MDA-MB-231 cells treated with PA3264. Data were presented as mean ± SEM, n = 3, *p < 0.05, **p < 0.01, ***p < 0.001 vs. the control group
