L-谷氨酸 γ-（对硝基苯胺） 盐酸盐

应用

L-Glutamic acid γ-(p-nitroanilide) hydrochloride has been used as a solute carrier family 1 member 5 (SLC1A5) inhibitor:
or an inhibitor of the cell membrane glutamine transporter to study the effects of blocking glutamine uptake on esophageal adenocarcinoma (EACC) and thioredoxin-interacting protein (TXNIP)in glutamine ELISA assay to treat confluent differentiated uninfected human colonoid monolayer (HCM) in apical and basolateral compartments to study its effectsto study its effect on SLC1A5_var-mediated mitochondrial glutamine transport inhibitionto study its effects on cellular glutathione levels, cellular reactive oxygen species (ROS) levels, and mitochondrial ROS levels

生化/生理作用

L-Glutamyl-p-nitroanilide (GPNA) is commonly used to block the glutamine (Gln) transporter alanine-serine-cysteine transporter 2 (ASCT2). It can also inhibit sodium-dependent and independent amino acid transporters. GPNA, γ-glutamyltransferase (GGT) substrate plays a key role in the hydrolysis of its γ-glutamyl bond and the subsequent release of the chromogen, p-nitroaniline (PNA).
