Beschreibung
Z-VAD-FMK (187389-52-2), cell-permeable, methyl ester form. Potent, irreversible pan-caspase inhibitor. Inhibits caspase activity and apoptosis induction in a variety of cell types (IC50 = 1.5 μM). Active in vivo.
Verwenden
Z-VAD(OMe)-FMK is a cell-permeable, competitive, and irreversible inhibitor of all caspases. Through this action, it inhibits cleavage of poly(ADP-ribose) polymerase, preventing apoptosis when used at 10-50 μM. It also blocks caspase-mediated apoptosis in vivo. Z-VAD(OMe)-FMK effectively prevents caspase action in inflammasomes.[Cayman Chemical]
Verwenden
Z-VAD-FMK is a caspase inhibitor that inhibits apoptosis and caspase processing in Jurkat T cells treated with low concentrations of z-FA-CMK.
Definition
ChEBI: Z-Val-Ala-Asp(OMe)-CH2F is a tripeptide consisting of Z-Val-Ala-Asp(OMe) in which the C-terminal OH group has been replaced by a fluoromethyl group. An irreversible pan-caspase inhibitor. It has a role as an apoptosis inhibitor and a protease inhibitor. It is a carbamate ester, a tripeptide and an organofluorine compound.
Allgemeine Beschreibung
A cell-permeable, irreversible, pan-caspase inhibitor. Shown to enhance the freeze-thaw survival of human embryonic stem cells. Inhibits Fas-mediated apoptosis in Jurkat T cells. Also reported to inhibit Peptide: N-glycanse (PNGase) in vitro amd in vivo. When using with a purified recombinant enzyme, pretreatment with an esterase is required.
Biologische Aktivität
Cell-permeable, irreversible pan-caspase inhibitor. Inhibits caspase processing and apoptosis induction in tumor cells in vitro (IC 50 = 0.0015-5.8 mM). Active in vivo .
Biochem/physiol Actions
Cell permeable: yes
Enzyminhibitor
This tripeptide halomethyl ketone (FWfree-acid = 467.49 g/mol; Soluble to 9.35 mg/ml in DMSO; CAS RegistryNumber = 187389-52-2), also known as Z-VAD-FMK and caspase inhibitor VI, is a broad-spectrum caspase inhibitor that blocks caspase-mediated apoptosis. Z-VAD-FMK inhibits caspase processing (IC50 = 0.0015–5.8 mM, depending on enzyme and cell type). The aspartate methyl ester derivative (FW = 467.49 g/mol), also known as caspase inhibitor I, is far more cell-permeable. Target (s) : caspases; caspase-1; caspase-2; caspase-3; caspase-4 ; caspase 5; caspase-6; caspase-7; caspase-8 ; caspase-9; caspase-10.
