Compound 9i induces cell death. Fluorescence images of (a, d) DAPI- and (b, e) PI-stained cells. HeLa cells were treated with (a–c) a vehicle control or (d–f) 5 μM of 9i for 24 hours and stained with DAPI and PI. Arrowheads indicate the cells with condensed chromatin and PI staining. DMSO was used as a vehicle control. DAPI was used to stain the nucleus. Scale bar represents 100 μm.
