Z-DEVD-FMK
Z-DEVD-FMK (CAS 210344-95-9) is a tetrapeptide inhibitor primarily targeting caspase-3, a protease involved in apoptotic neuronal cell death. Beyond caspase-3 inhibition, Z-DEVD-FMK also directly suppresses calpain-mediated proteolysis, notably reducing calpain-induced spectrin degradation. In vitro studies confirm Z-DEVD-FMK attenuates necrotic neuronal death, independently of caspase-3 activity. In vivo, following traumatic brain injury (TBI) or cerebral ischemia, administration of Z-DEVD-FMK limits lesion size, reduces tissue damage, and improves functional neurological outcomes, likely due to combined inhibition of caspase-3 and calpain pathways.

|
Cell lines |
WM9, WM35, WM98-1 and WM793 cells |
|
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°C for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20°C for several months. |
|
Reaction Conditions |
20 μM, 24 hours |
|
Applications |
To demonstrate the importance of caspase activation in TRAIL-induced apoptosis. Z-DEVD-FMK was added to melanoma cells along with TRAIL. Z-DEVD-FMK was only able to partially inhibit the cytotoxic effects of TRAIL. The decreased ability of Z-DEVD-FMK to inhibit death may result from the ability of the peptide to enter the cell. |
| Animal experiment: [2] | |
|
Animal models |
Male C57Bl/6 mice with controlled cortical impact (CCI) injury |
|
Dosage form |
Intracerebroventricular injection, 160 ng. |
|
Applications |
To assess motor recovery, mice were tested for the ability to traverse a narrow, suspended beam during recovery over a 21-day period. Mice treated 1 hour after CCI performed significantly better than did vehicle controls on days 7, 14, and 21 after injury. Mice treated 4 hours after CCI performed significantly better than controls only on day 21 after injury, but this was an isolated observation, as they did not show a trend toward better performance compared with other treatment groups on any other testing day. |
|
Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
