l-arginine

L-Arginine (L-Arg) is a substrate for endothelial nitric oxide synthase (eNOS), participating in protein synthesis, polyamine production, and cellular signaling regulation. L-Arginine is transported into vascular smooth muscle cells via the cationic amino acid transporter family and metabolized into nitric oxide, polyamines, or L-proline. L-Arginine is an effective vasodilator and can be used to induce experimental acute pancreatitis.

L-Arginine hydrochloride serve as substrates and nitrogen donors for endothelial nitric oxide synthase (eNOS) to produce nitric oxide (NO). They are transported into vascular smooth muscle cells via cationic amino acid transporters, where they are metabolized into NO, polyamines, or L-proline. As effective vasodilators, they are commonly used to induce experimental acute pancreatitis models.

L-Arginine Decarboxylase, Escherichia coli (EC 4.1.1.19), is a carboxy-lyase enzyme that cleaves carbon-carbon bonds. It utilizes L-arginine as a substrate and produces two products: agmatine and CO2.

Nω-Hydroxy-nor-L-Arginine Dihydrochloride is a competitive and reversible inhibitor of arginase

α-(difluoromethyl)-DL-Arginine (RMI 71897) is an enzyma-activated, irreversible inhibitor of arginine decarboxylase for E. coli (Ki = 800 μM), Pseudomonas aeruginosa, and Klebsiella pneumoniae. At 0.01 mM, it has been shown to prevent osmotic stress-induced increases in arginine decarboxylase activity and putrescine synthesis in oat leaf cells. When combined with a variety of polyamine analogues, α-(difluoromethyl)-DL-Arginine inhibited the growth of Trypanosoma Crui in mammalian host cells at a minimum concentration of 10 mM and prevented the growth of Trypanosoma Crui in T-cell receptor alpha-deficient mouse models.

N-Acetyl-L-arginine (Ac-Arg-OH), an N-acyl-L-alpha-amino acid with a strong basic nature (based on its pKa), has elevated serum levels in hyperargininemic patients and is associated with several diseases, including uremia and colorectal cancer. In untreated hyperargininemic patients, it reaches its highest levels in cerebrospinal fluid. It has also been detected in apples and loquats, suggesting it could be a potential biomarker for consumption of these foods. Additionally, a low-arginine diet combined with sodium benzoate therapy leads to a marked decrease in plasma N-acetyl-L-arginine concentrations.

DL-Arginine is deployed in the study of amino acid complexation dynamics and the formation of crystal structures.
