Chemical structure

Z-VDVAD-FMK

Biological Activity

Irreversible caspase-2 inhibitor. Attenuates oxyhemoglobin-induced cleavage of PARP and apoptosis in endothelial cells.
Targets Caspase-2          
IC50            

Protocol

Cell experiment [1,2]:

Cell line

Jurkat T-lymphocytes

Preparation method

The solubility of this compound in DMSO is >10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months.

Reacting condition

25 or 100 μM; 1 or 22 h

Applications

Jurkat T-lymphocytes pretreated with 25 μM Z-VDVAD-FMK for 1 h, or stably transfected with pro-caspase-2 antisense (Casp-2/AS) are refractory to cytochrome c release stimulated by etoposide. According to the MTT-assay, Jurkat cells treated with 100 μM Z-VDVAD-FMK for 22 h prevented doxorubicin-induced nuclear apoptosis, but not cell death.

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.
