Z-DEVD-FMK

Z-DEVD-FMK (210344-95-9) is a cell-permeable trimethyl ester form of the irreversible caspase-3 inhibitor DEVD-FMK (fluoromethylketone) with IC50 = 130 nM.1,2 Methyl esters confer cell permeability and are hydrolyzed to the active COOH form via intracellular esterases. Inhibits caspase-3-dependent apoptosis and pyroptosis in a variety of cell lines.3,4 Active in vivo.5
