Mechanism of Action

Targets/IC₅₀/Ki	Caspase-8
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. This compound (50 μM) reduces ceramide-induced cardiomyocyte death and significantly inhibits the activation of caspase 3. Inhibition of caspase-8 by this chemical 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.
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. This compound promotes neuronal survival and regeneration of injured retinal ganglion cells after CNS injuries.
