    • In this method, fixation in formaldehyde prevents extraction of low molecular weight DNA from apoptotic cells and thus the cell cycle distribution estimates both apoptotic and non-apoptotic cells.

    • The AMC liberated was measured using a spectrofluorometer (Hitachi F-2500 model, Hitachi Ltd., Tokyo, Japan) with an excitation wavelength of 380 nm and an emission wavelength range of 400-550 nm. Data were collected as the integer of relative fluorescence intensity minus the background fluorescence. As a control, the cell-permeable caspase-3 inhibitor zDEVD-fmk (Bachem, Bubendorf, Switzerland) was used.

    • 50 apoptotic concentrations of compounds 2a, 3a, and 4b for 6 h, lysed and 30 μg of protein from cell extracts were incubated with the specific caspase-3 substrate Ac-DEVD-AMC for 1 h at 37°C. Results represent the integer of relative fluorescence intensity from the AMC liberated from reaction minus the background fluorescence. The activation of caspase-3 by compounds 2a was inhibited in the presence of zDEVD-fmk (20 μM). Values are means±SE of three independent experiments.
