Biological Activity

Description Z-DEVD-FMK (Caspase-3 Inhibitor) is a specific, irreversible Caspase-3 inhibitor, and also shows potent inhibition on caspase-6, caspase-7, caspase-8, and caspase-10.
Caspase-3 [1]
In vitro

Z-DEVD-FMK (1–200 μM) inhibits D4-GDI cleavage and apoptosis in a concentration-dependent manner. [1] Z-DEVD-FMK reduces ceramide-induced cardiomyocyte death and significantly inhibits the activation of caspase 3. [3] Z-DEVD-FMK (100μM) attenuates OxyHb-induced cell detachment, reduced caspase-2 and -3 activities, abolishes OxyHb-induced DNA ladders, and prevents OxyHb-induced cleavage of PARP in cultured brain microvessel endothelial cells. [4] Z-DEVD-FMK (100 μM) blocks MPP+-induced increases in caspase-3 enzyme activity. Z-DEVD-FMK dose dependently blocks 6-OHDA-induced apoptotic cell death with IC50 of 18 μM. [5]

In vivo Z-DEVD-FMK, before and after injury, markedly reduces post-traumatic apoptosis, and significantly improved neurological recovery. [2]

Protocol (from reference)

Kinase Assay:[5]
  • Caspase activity assay :

    Caspase-3 and caspase-9 activities are measured using fluorescent-based substrate. After treatment, the cells are resuspended in lysis buffer (50 mM Tris HCl, 1 mM EDTA, and 10 mM EGTA) containing 10 mM digitonin for 20 min at 37°C. Supernatants are treated with either of the fluorogenic substrates Ac-DEVD-AFC for caspase-3 or Ac-LEHD-AFC for caspase-9 for 1 h at 37°C and fluorescence is measured at excitation at 400 nm and emission at 505 nm using a Gemini XS fluorescence plate reade

Cell Research:[5]
  • Cell lines: N27 cells
  • Concentrations: ~50 μM
  • Incubation Time: 24 hours
  • Method: N27 cells are incubated with 100 μM 6-OHDA for 24 h or 300 μM MPP+ for 36 h in the presence or absence of 50 μM Z-DEVD-FMK and cell death is determined by MTT (3-(4,5-dimethylthiazol-3-yl)-2,5-diphenyl tetrazolium bromide) assay, which is widely used to assess cell viability. After treatment, the cells are incubated in serum-free medium containing 0.25 mg/ml MTT for 3 h at 37°C. Formation of formazan from tetrazolium is measured at 570 nm with a reference wavelength at 630 nm using a SpectraMax microplate reader.
Animal Research:[2]
  • Animal Models: Male Sprague Dawley rats with Brain trauma.
  • Dosages: 160 ng
  • Administration: Intracerebroventricular administration
