Clear solution
5%DMSO Corn oil
2.25mg/ml Taking the 1 mL working solution as an example, add 50 μL of 45 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

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

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]
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]
