Pan-Caspase inhibitor

Z-VAD-FMK is a cell-permeable pan-caspase inhibitor that irreversibly binds to the catalytic site of caspase proteases [1].

The peptide is O-methylated in the P1 position on aspartic acid, providing enhanced stability and increased cell permeability.

Z-VAD-FMK is used in apoptosis studies and also in inflammasome studies. It is a potent inhibitor of caspase-1 activation in NLRP3-induced cells [2].

Moreover, through the inhibition of caspases 3, 7 and 8, Beclin1 is stabilized and autophagy is promoted by Z-VAD-FMK.
