NCIt definition : A zinc-dependent enzyme isolated from a strain of the bacterium Pseudomonas. Because
glucarpidase rapidly hydrolyzes methotrexate into inactive metabolites, it may be
useful as a rescue agent for methotrexate-induced nephrotoxicity. In antibody-directed
enzyme prodrug therapy (ADEPT), this agent is conjugated with an antibody that binds
to a specific tumor cell type, allowing for glucarpidase-catalyzed activation of a
co-administered prodrug at the site of the tumor.;
Alternative definition : NCI-GLOSS: A bacterial enzyme that breaks down proteins and other substances, including
methotrexate. It is being studied in the treatment of toxic effects caused by methotrexate.
It may also help activate certain drugs to kill cancer cells. It is a type of chemoprotective
agent and a type of prodrug activator.;
