Reactivity of iron(II)-bound nitrosyl hydride (HNO, nitroxyl) in aqueous solution
(Elsevier Science Inc, 2013-01)
The reactivity of coordinated nitroxyl (HNO) has been explored with the [FeII(CN)5HNO]3 - complex in aqueous medium, pH 6. We discuss essential biorelevant issues as the thermal and photochemical decompositions, the ...
Effect of nitroxyl on the hamster retinal nitridergic pathway
(Pergamon-Elsevier Science Ltd, 2007-11)
There is a growing body of evidence on the role of nitric oxide (NO) in retinal physiology. Recently, interest has developed in the functional role of an alternative redox form of NO, namely nitroxyl (HNO/NO), because it ...
Helpful correlations to estimate the pKaof coordinated HNO: a potential-pH exploration in a pendant-arm cyclam-based ruthenium nitroxyl
(Royal Society of Chemistry, 2021-01)
The acid-base speciation of coordinated azanone (HNO) remains a highly relevant topic in bioinorganic chemistry. Ruthenium nitroxyl complexes with sufficient robustness towards ligand loss have gained significance as ...
Coordinated nitroxyl anion is produced and released as nitrous oxide by the decomposition of iridium-coordinated nitrosothiols
(Elsevier Science Sa, 2011-01)
The aqueous decomposition of the iridium coordinated nitrosothiols (RSNOs) trans-K[IrCl4(CH3CN)NOSPh] (1), and K 2[IrCl5(NOECyS)] (2, ECyS = cysteine ethyl ester), was studied by MS analysis of the gaseous products, ESI-MS, ...
Interaction between nitroxyl radicals and CdTe quantum dots: Determination of fluorescence-quenching mechanisms in aqueous solution
(2019)
The present work characterizes the optical properties of CdTe quantum dots (CdTe QDs) after interaction with nitroxyl radicals based on steady-state and time-resolved fluorescence spectroscopy studies. QDs of different ...
Aorta from angiotensin II hypertensive mice exhibit preserved nitroxyl anion mediated relaxation responses
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTDLONDON, 2012)
Hypertension is a disorder affecting millions worldwide, and is a leading cause of death and debilitation in the United States. It is widely accepted that during hypertension and other cardiovascular diseases the vasculature ...
Nitrosyl-Centered Redox and Acid–Base Interconversions in [Ru(Me 3 [9]aneN 3 )(bpy)(NO)] 3,2,1+ . The p K a of HNO for its Nitroxyl Derivative in Aqueous Solution
(American Chemical Society, 2014-01)
This work reports the preparation of a new 6-coordinated nitrosyl compound and its use as a model to explore the redox and acid–base properties of the three redox states of bound nitrosyl (formally NO+, NO•, NO–/HNO) in ...
Rapid generation of HNO induced by visible light
(Royal Society of Chemistry, 2017-04)
We present a new method for controlled generation of HNO, based on the combination of a pH photoactuator induced by visible light with an HNO donor activated by pH increase. This method avoids the use of UV light, and in ...
Nitric Oxide and Nitroxyl Products from the Reaction of L-Cysteine with trans-[RuNO(NH3)(4)P(OEt)(3)](PF6)(3)
(Wiley-Blackwell, 2015-02-01)
The reaction between the trans-[RuNO(NH3)(4)P(OEt)(3)](PF6)(3) and L-cysteine (RS-) was studied over a pH range of 2.0-7.4. In this reaction, the concentrations of NO and HNO produced varied as a function of the pH of the ...
