L-GLUTAMIC ACID GAMMA-(P-NITROANILIDE) HYDROCHLORIDE

Description

L-γ-Glutamyl-p-nitroanilide (67953-08-6; GPNA) is a substrate for γ-glutamyl transpeptidase. GPNA is used for the determination of γ-glutamyl transpeptidase hydrolytic activity via spectrophotometric monitoring of p-nitroaniline released by the action of the enzyme on GPNA.1 GPNA has also been shown to be an inhibitor of glutamine uptake – solute-linked carrier family A1 member 5 (SLC1A5).2?Cellular uptake of L-glutamine (regulated by SLC1A5) is a rate-limiting step that activates mTOR and is, thus, an interesting cancer chemotherapy target.3

The Uses of L-GLUTAMIC ACID GAMMA-(P-NITROANILIDE) HYDROCHLORIDE

L-Glutamic acid gamma-(p-nitroanilide) is used in methods of treating cancers having a deregulated NRF2/KEAP1 pathway.

What are the applications of Application

L-Glutamic acid γ-(p-nitroanilide) hydrochloride is a substrate for gamma-glutamyl transpeptidase (GGT).
