| Kinase experiment [1]: | |
|
Preventing the processing of CPP32 to its active form |
Z-VAD.FMK inhibits apoptosis by inhibiting the activation of CPP32, which presumably blocked the process by interfering directly with the processing of CPP32. |
| Cell experiment [2]: | |
|
Cell lines |
Human CD4+ (~ 97%) and CD8+ T (~ 98%) 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. |
|
Reacting time |
24 h |
|
Applications |
z-VAD-FMK dose-dependently inhibited T cell proliferation mediated through the co-stimulation with anti-CD3 and anti-CD28. z-IETD-FMK was less effective at 25 and 50 μM, but inhibited T cell proliferation at the 100 μM concentration. |
| Animal experiment [3]: | |
|
Animal models |
C57BL mice |
|
Dosage form |
1.25 mM, ear provocation |
|
Applications |
The right ear swelling degree, weight differences and thickness between two ears in the 1.25 mML Z-VAD-FMK group were significantly lower than those of the negative control (NC). The levels of INF-γ and IL-2 in the ear skin lesions, the mean intensity of BrdU in T lymphocytes, and the percent of activation markers-positive T lymphocytes were all lower than those of NC. |
|
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. |

Abstract
The caspase inhibitor Z-VAD-FMK exhibits immunosuppressive and anti-proliferative activities in T cell without inhibiting the activity of caspases 8 and 3, where it inhibits NF-KB, the expression of CD25 and FasL-induced apoptosis.
Abstract
The effects of Z-VAD-FMK, a caspase inhibitor, on T lymphocytes and the elicitation of murine ACD were investigated.
Abstract
Intracerebroventricular administration of Z-VAD-FMK, a caspase inhibitor restricted by blood-brain barrier, to post-radiation rats resulted in reduced numbers of TUNEL-positive cells in the hypoglossal nucleus, suppressed expression and activation of caspases 3/8/9 and decrease appearance of cytochrome c in the cytosolic fraction.
Abstract
Z-VAD-FMK is a caspase inhibitor that inhibits mitochondria-related apoptotic effects induced by CIN.
Abstract
Early direct infusion of Z-VAD-FMK, a caspase inhibitor, into cochlear leads to accelerated hearing recovery and reduced hair cell loss in pigs suffering gunshot noise-induced trauma.
Z-VAD-FMK, an inhibitor of ICE-like proteases, inhibits apoptosis in THP.1 cells induced by diverse stimuli1 and Fas antigen-induced apoptosis in Jurkat T-cells2. It inhibits apoptosis by blocking the activation of proCPP32 into its active form, rather than by preventing the proteolytic action of CPP32 directly.
Z- VAD-FMK inhibits the formation of large kilobasepair fragments of DNA induced by diverse stimuli. Z-VAD-FMK had little or no effect on STS-induced necrotic cell death suggesting that the ICE-like protease activity was not involved in necrosis3.
Z-VAD-FMK almost completely inhibited the formation of large kilobasepair induced by all four stimuli. Similarly Z-VAD-FMK almost completely inhibited the enhanced formation of large kilobasepair fragments induced by thapsigargin or cycloheximide in the presence of TLCK, in good agreement with its ability to inhibit apoptosis induced by these treatments. These stimuli also induced internucleosomal cleavage of DNA, which was inhibited by Z-VAD-FMK. These results suggested that an ICE-like protease(s) acts at a stage prior to the formation of large kilobasepair fragments of DNA3.
