NG-nitro L-arginine methyl ester and other alkyl esters of arginine are muscarinic receptor antagonists.
Analogues of L-arginine with modifications at the terminal guanidino nitrogen and/or the carboxyl terminus of the molecule have been widely used for their ability to inhibit the production of nitric oxide and are thought to be competitive antagonists of nitric oxide synthase. The present studies were designed to test the possibility that these agents are also muscarinic receptor antagonists. Ac...
متن کاملThe role of nitric oxide synthase in endotoxin-induced uveitis: effects of NG-nitro L-arginine.
PURPOSE To evaluate the role of nitric oxide synthase (NOS) in endotoxin-induced uveitis (EIU). METHODS EIU was caused in Lewis rats by injecting lipopolysaccharide (LPS) into the foot pad, and the effects of an NOS inhibitor, NG-nitro L-arginine (NA), was comparatively studied by the simultaneous administration of NA and LPS. Total NOS and inducible NOS (iNOS) activities were differentially ...
متن کاملCoronary vasoconstriction in the conscious rabbit following intravenous infusion of L-NG-nitro-arginine.
Intravenous infusion of L-NG-nitro-arginine, an inhibitor of endothelial nitric oxide (NO) synthesis, produced vasoconstriction in the coronary, cerebral, renal and duodenal vascular beds of the conscious rabbit. In this study, using radiolabelled microspheres, we provide in vivo evidence for a basal NO-dependent vasodilator tone in the coronary vascular bed.
متن کاملThe Inhibition of Arginase by Nω-Hydroxy-l-Arginine Controls the Growth of Leishmania Inside Macrophages
Polyamine synthesis from l-ornithine is essential for Leishmania growth. We have investigated the dependence of Leishmania infection on arginase, which generates l-ornithine, in macrophages from BALB/c, C57BL/6, and nitric oxide synthase II (NOS II)-deficient mouse strains. We have found that N(omega)-hydroxy-l-arginine (LOHA), a physiological inhibitor of arginase, controls cellular infection ...
متن کاملInactivation of macrophage nitric oxide synthase activity by NG-methyl-L-arginine.
.N = O synthase catalyzes the oxidation of one of the two chemically equivalent guanido nitrogens of L-arginine to nitric oxide (.N = O). NG-Methyl-L-arginine has been previously characterized as a potent competitive inhibitor of both major types of .N = O synthases. Initial rate kinetics were performed with a spectrophotometric assay based on the oxidation of oxy- to methemoglobin by .N = O. N...
