Airway inflammation and remodeling are major features of chronic obstructive pulmonary disease (COPD), whereas pulmonary hypertension is a common comorbidity associated with a poor disease prognosis. Recent studies in animal models have indicated that increased arginase activity contributes to features

The ability of murine macrophage nitric oxide synthase (NOS) to utilize peroxides in place of O2 and NADPH was investigated using hydrogen peroxide (H2O2), tert-butylhydroperoxide, and cumene hydroperoxide with both L-arginine and NG-hydroxy-L-arginine (L-NHA) as substrates. Of the three peroxides

NG-hydroxy-L-arginine, an intermediate in the biosynthesis of nitric oxide (NO), has been found to be a uniquely potent competitive inhibitor of rat liver arginase. Among previously reported inhibitors of arginase and the eight arginine analogs tested herein, only NG-hydroxy-L-arginine was

l-Homoarginine (hArg) is biosynthesized from l-arginine (Arg) and l-lysine (Lys) by arginine:glycine amidinotransferase (AGAT). AGAT also catalyzes the formation of guanidinoacetate (GAA) from Arg and glycine (Gly). GAA is converted to creatine (N-methyl guanidinoacetate) by guanidinoacetate N-methyl-transferase (GAMT).
