Embodiments are directed towards methods of inducing
caspase activity. The methods include contacting a
cell with a treatment compound represented by the following Formula (I): where R1 is selected from
hydrogen or an
alkyl group having from 1 to about 16 carbon atoms; R2 is selected from a hydroxyl group, a tosylate group, an
alkoxy group of the formula OR3 where R3 is selected from an
alkyl group having from 1 to about 16 carbon atoms, or an ester group of the formula OCOR4, where R4 is an
alkyl group having from 1 to about 16 carbon atoms, and n is from 4 to 46,000, with the proviso that when R1 is
hydrogen and R2 is a
hydroxy group the treatment compound has a number average molecular weight from 10,100 to 2,000,0000 g / mol.
