Z-VDVAD-FMK

• Background:

  Jurkat T-lymphocytes treated with an irreversible caspase-2 inhibitor, benzyloxycarbonyl-Val-Asp (OMe) -Val-Ala-Asp (OMe) -fluoromethyl ketone (Z-VDVAD-FMK), or stably transfected with pro-caspase-2 antisense (Casp-2/AS) are refractory to cytochrome c release stimulated by etoposide1.When etoposide-induced activation of pro-caspase-2 is subverted by Z-VDVAD-FMK or stable transfection of pro-caspase-2 antisense, cytochrome c release and other manifestations of apoptosis are attenuated.OxyHb significantly activated both caspase-2 and caspase-3 in bovine brain microvessel endothelial cells. The irreversible caspase inhibitors Z-VDVAD-FMK (caspse-2 inhibitor) and Z-DEVD-FMK (caspase-3 inhibitor) significantly reduced cell detachment, caspase-2 and -3 activities, DNA ladders, and proteolytic cleavage of PARP2. Activation of caspase-2 and caspase-3 is essential for OxyHb induced apoptosis in endothelial cells, and Z-VDVAD-FMK and Z-DEVD-FMK have the potential to protect cells.The minimal-length inhibitor of caspase-2, Z-VDVAD-fmk, which also inhibits caspases 3 and 73, prevented doxorubicin-induced nuclear apoptosis, but not cell death4.

• Description:

  Z-VDVAD-FMK is a synthetic peptide that irreversibly inhibits the activity of caspase-2. It attenuates oxyhemoglobin-induced cleavage of PARP and apoptosis in endothelial cells.
