Nitric oxide (NO) is a potent intra- and intercellular messenger involved in the control of vascular tone, neuronal signalling and host response to infection. In mammals, NO is synthesized by oxidation of l-arginine catalysed by hemeproteins called NO-synthases with intermediate

Bioorganic & medicinal chemistry, 10(9), 3049-3055 (2002-07-12)
Enzymatic generation of nitric oxide (NO) by nitric oxide synthase (NOS) consists of two oxidation steps. The first step converts L-arginine to N(G)-hydroxy-L-arginine (NOHA), a key intermediate, and the second step converts NOHA to NO and L-citrulline. To fully probe

The electrochemical properties of a series of N-substituted-N'-hydroxyguanidines were studied. Two oxidation potentials of each compound were obtained by cyclic voltammetry. The E(ox1) values were from 0.51 to 0.62V, while the E(ox2) values were from 1.14 to 1.81V in acetonitrile

The interaction of various N-alkyl- and N-aryl-N'-hydroxyguanidines with recombinant NOS containing or not containing tetrahydrobiopterin (BH(4)) was studied by visible, electronic paramagnetic resonance (EPR), and resonance Raman (RR) spectroscopy. N-Hydroxyguanidines interact with the oxygenase domain of BH(4)-free inducible NOS (BH(4)-free

Free radical biology & medicine, 24(1), 1-10 (1998-01-22)
The oxidative denitrification of the antitumour agent hydroxyguanidine (HOG) has been investigated by radiolysis methods and EPR spectroscopy. The azide radical (N3.), a model one-electron oxidant, reacts with HOG with the rate constant 5.1 x 10(9) dm3 mol(-1) s(-1) to
