Description générale

Cell permeable. A key intermediate in the biosynthesis of nitric oxide by constitutive nitric oxide synthase (cNOS). NOHA can be efficiently oxidized to nitric oxide and citrulline by cytochrome P450 system. A potent inhibitor of liver and macrophage arginase (Ki = 150 µM).
Cell-permeable. A key intermediate product in the biosynthesis of nitric oxide from arginine by constitutive nitric oxide synthase (cNOS). Formed by the NADPH-dependent hydroxylation of L-arginine. NOHA can be efficiently oxidized to nitric oxide and citrulline by cytochrome P450, providing an alternative biosynthetic route for the production of nitric oxide. A potent inhibitor of liver and macrophage arginase (Ki = 150 µM).

N omega-Hydroxy-L-arginine (L-NOHA) is a potent inhibitor of the hydrolysis of L-arginine (L-Arg) to L-ornithine (L-Orn) catalyzed by purified bovine liver arginase (BLA). It appears as one of the most powerful arginase inhibitors reported so far (Ki = 150 microM).
