Nitroxyl (HNO) is a redox sibling of nitric oxide (NO) that targets distinct signalling pathways with pharmacological endpoints of high significance in the treatment of heart failure. Beneficial HNO… (More)
The catalytic disproportionation of NH(2)OH has been studied in anaerobic aqueous solution, pH 6-9.3, at 25.0 degrees C, with Na(3)[Fe(CN)(5)NH(3)].3H(2)O as a precursor of the catalyst,… (More)
A group of Piloty's acid (N-hydroxybenzenesulfonamide) derivatives were synthesized and fully characterized in order to assess the rates and pH of HNO (azanone, nitroxyl) donation in aqueous media.… (More)
The reduction of NO(•) to HNO/NO(-) under biologically compatible conditions has always been thought as unlikely, mostly because of the negative reduction potential: E°(NO(•),H(+)/HNO) = -0.55 V vs… (More)
We report an investigation of the reaction between (S)-nitroso-l-cysteine ethyl ester and l-cysteine ethyl ester as a model of physiologically relevant transnitrosation processes. Our theoretical and… (More)
The role of NO in biology is well established. However, an increasing body of evidence suggests that azanone (HNO), could also be involved in biological processes, some of which are attributed to NO.… (More)
Most physiological processes in mammals are synchronized to the daily light:dark cycle by a circadian clock located in the hypothalamic suprachiasmatic nucleus. Signal transduction of light-induced… (More)
Heme proteins are found in all living organisms and are capable of performing a wide variety of tasks, requiring in many cases the binding of diatomic ligands, namely, O(2), CO, and/or NO. Therefore,… (More)
Azanone (HNO, nitroxyl) is a highly reactive and short-lived compound with intriguing and highly relevant properties. It has been proposed to be a reaction intermediate in several chemical reactions… (More)
