Biological Activity

Description Z-IETD-FMK (Caspase-8 Inhibitor, Z-IE(OMe)TD(OMe)-FMK) is a specific Caspase-8 inhibitor. Z-IETD-FMK is also an inhibitor of granzyme B.
Targets
Caspase-8 [1]
In vitro
In vitro

Z-IETD-FMK, which inhibits the cleavage of caspase-8 and partially inhibits the cleavage of caspase-3 and PARP, prevents the execution of apoptosis in retinal cells exposed to different apoptotic stimuli. [1]

Z-IETD-FMK (50 μM) reduces ceramide-induced cardiomyocyte death and significantly inhibits the activation of caspase 3. [2]

Inhibition of caspase-8 by Z-IETD-FMK affects the generation of activated/memory T cells and T cell cytokine production, and decreases NF-kappaB responses to TCR:CD3 engagement in T cell cultures. [3]

Cell Research Cell lines Rat neonatal cardiomyocytes
Concentrations 50 µM
Incubation Time 24 h
Method

Drugs were added to the cell culture medium simultaneously with ceramide, and surviving cells were counted 24 hours later.

In Vivo
In vivo

In vivo, inhibition of caspase-8 by Z-IETD-FMK reduces memory/activated CD4 and CD8 T cells, and increases susceptibility to T. cruzi infection. [3]

Z-IETD-FMK promotes neuronal survival and regeneration of injured retinal ganglion cells after CNS injuries. [4]

Animal Research Animal Models T. cruzi-infected mice

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
