Effect of compounds 1–7 on caspase-3 enzymatic activity. Apoptotic HepG2 cell lysates were individually incubated with various concentrations (12.5–200 μM) of purpuride (1) and 200 µM of compounds 2–7. A caspase-3 inhibitor (5 µM), Z-DEVD-fmk, was used as a positive control. Data are mean + SD of three independent experiments. Ctl = A control without compounds.
