Biological Activity

Description Z-IETD-FMK is a specific Caspase-8 inhibitor.
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.

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]

Bio Calculators

Molarity Calculator

Molarity Calculator

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:

Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)

  • Mass
    Molecular Weight

*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).

Dilution Calculator

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration (start) x Volume (start) = Concentration (final) x Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

  • C1

* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
