Usage

Description

N'-Nitro-L-arginine-methyl ester hydrochloride, also known as L-NAME, is a more soluble analog of arginine and serves as a competitive, slowly reversible inhibitor of endothelial nitric oxide synthase (IC50 = 500 nM). It requires hydrolysis of the methyl ester by cellular esterases to become a fully functional inhibitor (L-NNA), which exhibits some selectivity for inhibition of neuronal and endothelial isoforms. L-NAME is characterized by its crystalline chemical properties and is defined as a hydrochloride obtained by combining Ngamma-nitro-L-arginine methyl ester with one equivalent of hydrochloric acid.

Uses

Used in Pharmaceutical Industry:
N'-Nitro-L-arginine-methyl ester hydrochloride is used as a synthesis compound for N/CD13 inhibitors, which play a crucial role in tumor invasion, metastasis, and angiogenesis. It is also utilized in the preparation of spirocyclic lactam as a type II' β-turn inducer, contributing to the development of novel pharmaceutical compounds.
Used in Research Applications:
L-NAME is employed in research settings to inhibit cGMP formation in endothelial cells with an IC50 of 3.1 μM (in the presence of 30 μM arginine) and reverses the vasodilation effects of acetylcholine in rat aorta rings with an EC50 of 0.54 μM. This makes it a valuable tool for studying the roles of nitric oxide synthase and related pathways in various biological processes.

Novel L-arginine derivatives as aminopeptidase N inhibitors: design, chemistry, and pharmacological evaluation

Considering the important roles played in tumor, aminopeptidase N has been an appealing target for anti-tumor drug development. Here, a serial of novel aminopeptidase N inhibitors with L-arginine scaffold were designed, synthesized and evaluated for aminopeptidase N inhibitory activities. The preliminary anti-enzyme activity assay demonstrated that compounds 5e, 5h, 11e, 11g, and 11h showed comparable activities with the positive control bestatin, an approved aminopeptidase N inhibitor. In vitro anti-proliferation assay, compound 5f showed excellent activities against four kinds of tumor cells which overexpress aminopeptidase N. In vivo anti-metastasis assay, compounds 5f and 11g exhibited better activities than bestatin. So 5f and 11g should be lead compounds as novel aminopeptidase N inhibitors for further development.

A class of novel Schiff's bases: Synthesis, therapeutic action for chronic pain, anti-inflammation and 3D QSAR analysis

To discover analgesics for treating chronic pain 17 novel Schiff's bases, N,N′-(Z-allylidene-1,3-diyl)bisamino acid methyl esters were prepared from 1,1,3,3,-tetramethoxypropane and amino acid methyl esters. On tail-flick mouse model 20 μmol/kg of these Schiff's bases were orally administered, the analgesic action started 30 min after administration, reached the maximum 120 min after administration, and at 180 min this action was still observed. On a xylene-induced ear edema mouse model 20 μmol/kg of these Schiff's bases exhibited desirable anti-inflammation. Thus the present Schiff's bases are able to treat chronic pain from inflammation. The effect of the side chains of the amino acid residues of these Schiff's bases on the analgesic activity was explained with 3D QSAR.
