Z-DEVD-FMK Usage And Synthesis

Uses

Z-DEVD-FMK is an irrversible caspase-3 inhibitor used as an anaesthetic agent. In addition, it is proposed to increase the longevity of platelet storage.

Definition

ChEBI: Z-DEVD-FMK is a tetrapeptide consisting of Fmoc-L-aspartic acid 4-methyl ester, methyl L-alpha-glutamic acid 5-methyl ester, L-valine and the fluoromethyl ketone derived from the 1-carboxy group of L-aspartic acid 4-methyl ester coupled in sequence. It is a specific, irreversible caspase-3 inhibitor that also shows potent inhibition of caspase-6, caspase-7, caspase-8, and caspase-10. It has a role as an apoptosis inhibitor, an EC 3.4.22.56 (caspase-3) inhibitor and a neuroprotective agent.

General Description

A potent, cell-permeable, and irreversible inhibitor of caspase-3 as well as caspase-6, caspase-7, caspase-8, and caspase-10. When using with purified native or recombinant enzyme, pretreatment with an esterase is required. A 5 mM (250 μg/75 μl) solution of Z-DEVD-FMK (Cat. No. 264156) in DMSO is also available.

Biological Activity

Cell-permeable, irreversible inhibitor of caspase-3/CPP32; inhibits tumor cell apoptosis. Neuroprotective in rat hippocampus following seizures in vivo .

Biochem/physiol Actions

Cell permeable: yes

target

Caspase-3
