Identification
NameZ-Val-Ala-Asp fluoromethyl ketone
Accession NumberDB07744
TypeSmall Molecule
GroupsExperimental
Description

Non-methylated, competitive, and irreversible inhibitor of caspase 1, as well as other caspases,1 which can be used directly with purified enzymes. It does not require an esterase to hydrolyze the O-methyl ester like the cell-permeable form, Z-Val-Ala-Asp(O-Me) fluoromethyl ketone.
