Inhibitory effects of DHQ3 and 17-DR on MDA-MB-231 cells. a MDA-MB-231 cells were treated with various concentrations of analogs for 24, 48 or 72 h. Cell viability was measured by MTT assay. *p < 0.01, **p < 0.001. b Cells were treated with analogs for 24 h and the morphology was examined by light microscopy with differential interference contrast optics. c The colony-forming capability of MDA-MB-231 cells was measured using a colony formation assay after treatment with various concentrations of analogs for 5 days
