    Descripciòn

    Z-IETD-FMK (Z-IE(OMe)TD(OMe)-FMK) is a selective and cell permeable caspase-8 inhibitor[1]. Z-IETD-FMK is also a granzyme B inhibitor[5].

    IC50 & Target[1]

    Caspase-8

     

    In Vitro

    T-cellZ-IETD-FMK causes full inhibition only of the proapoptotic effect of TNFα with an IC50 of 0.46 μM[1]. Z-IETD-FMK and Z-VAD-FMK at non-toxic doses are found to be immunosuppressive and inhibit human T cell proliferation induced by mitogens and IL-2. They are shown to block NF-κB in activated primary T cells, but have little inhibitory effect on the secretion of IL-2 and IFN-γ during T cell activation[2]. Z-IETD-FMK inhibits the cleavage of caspase-8 and only partially inhibits the cleavage of caspase-3 and PARP. Z-IETD-FMK can prevent the execution of apoptosis in retinal cells exposed to different apoptotic stimuli[3].

    In Vivo

    Pharmacological inhibition of caspase-8 by z-IETD-FMK robustly reduces tumor growth and this is closely associated with a reduction in the release of pro-inflammatory cytokines, IL-6, TNF-α, IL-18, IL-1α, IL-33, but not IL-1β. Furthermore, inhibition of caspase-8 reduces the recruitment of innate suppressive cells, such as myeloid-derived suppressor cells, but not of regulatory T cells to lungs of tumor-bearing mice[4].

    T cell proliferation following mitogen stimulation is determined using [3H]-thymidine incorporation. In brief, PBMCs or purified T cells are seeded at 1×106 cells/mL in 96 well plates and stimulated with either PHA (5 μg/mL or co-stimulated with anti-CD3 mAb (5 μg/mL) and anti-CD28 mAb (2.5 μg/mL) in the presence or absence of caspase inhibitor Z-IETD-FMK. The cells are cultured for 72 h with the last 16 h pulsed with [[3H]-labelled methyl-thymidine (0.037 MBq) prior to harvest onto glass fibre filter mats using a Tomtec automated multi-well harvester[2].

    Mice: Mice are divided into three groups: (1) naive, non-treated, mice; (2) CTR (control), i.t. instilled with NMU; and (3) lung cancer-bearing mice treated with Z-IETD-FMK (0.5 μg per mouse). The involvement of caspase-8 in lung cancer development is the determined at different time points (3, 7 and 28 days)[4].

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
