(Sociedad Chilena de Química, 1998)This paper reports the scavenging of the nitro radical anion of nisoldipine by N-acetylcysteine assessed by cyclic volatammetry (CV) and EPR spectroscopic techniques. Studies by CV on the reactivity of the radical were ...
-
(Elsevier Ireland Ltd, 1996)The reactivity of the electrochemically generated nitro radical anion from nifedipine, a nitro aryl 1,4-dihydropyridine derivative, with relevant endobiotics and thiol-containing xenobiotics, was quantitatively assessed ...
-
(1996)The reactivity of the electrochemically generated nitro radical anion from nicardipine, nitrendipine and nimodipine, all nitro aryl 1,4-dihydropyridine derivative, with relevant thiols, was quantitatively assessed by cyclic ...

-
(American Chemical Society, 2020)In this article, we present a complementary analysis based on the reaction force F(xi)/reaction force constant kappa(xi) and noncovalent interactions (NCI) index to characterize the energetics (kinetic and thermodynamics) ...
-
(2012)Photoisomerization of a protein bound chromophore is the basis of the light sensing and signaling responses of many photoreceptors. Z-to-E photoisomerization of the Pr Cph1Δ2 phytochrome has been investigated by polarization ...
-
(Magnolia Press, 2015)Copyright © 2015 Magnolia Press. The hairy long-nosed armadillo, currently referred as Dasypus (Cryptophractus) pilosus, is an enigmatic species endemic to montane cloud forests and subparamo of Peruvian Andes. Its strikingly ...
-
(BENTHAM SCIENCE PUBL, 2005-04)The redox chemistry of different nitro compounds of biological significance is focused to understand how the reduction of the nitro group can play an active role in several aspects as: electroanalytical determinations, ...
-
(Elsevier Ltd, 1996)A process of recovery of copper from acid leach residual solution with 5-dodecylsalicylaldoxime dissolved in n-hexane was carried out at 30°C in a countercurrent tubular membrane extractor using a hollow fiber as solid ...
-
(1997)The communication describes a process of recovery and enrichment of Cu(ll) from mine waters in a liquid membrane extractor using hollow fibers as solid support. 5Dodecylsalicylaldoxime was used as extracting carrier for ...
-
(2012)Natural red colorants are highly appreciated by the food industry, and betalains are one such category. There are few sources in nature of betalains, which are commonly obtained from red beet as a colorant additive and ...
-
(BLACKWELL MUNKSGAARD, 2003-11)The title compound, [Cu2Cl4(C5H5NO)(2)](n), is a one-dimensional polymer in which the Cu-II atoms are alternately bridged by two O atoms [Cu...Cu = 3.2131 (10) Angstrom] and two Cl atoms [Cu...Cu = 3.7061 (11) Angstrom]. ...
-
(2010)When excess uronic acid over CrVI is used, the oxidation of d-glucuronic acid (Glucur) by CrVI yields D-glucaric acid (Glucar) and CrIII as final products. The redox reaction involves the formation of intermediate CrIV and ...
-
(2004)The oxidation of D-galacturonic acid by Cr-VI yields the aldaric acid and Cr-III as final products when a 30-times or higher excess of the uronic acid over Cr-VI is used. The redox reaction involves the formation of ...
-
(Elsevier Ireland Ltd, 1996)The electrochemical properties of nifuroxazide have been investigated in aqueous and aqueous-DMF mixed solvents. In aqueous media, a single, irreversible four-electron reduction occurs to give the hydroxylamine derivative. ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2003-07-18)A sensitive atomic spectrometric method for the redox speciation analysis of antimony in soils is described. The method is based on the selective generation of stibine from Sb(III) in a continuous flow system using atomic ...
-
(2010)Prompted by the recently reported capacity of the physiologically occurring Cu(I)-[glutathione]2 complex (Cu(I)-[GSH)]2) to reduce oxygen, the effect of various GSH-binding metals (Co2+, Cd2+, Zn2+, Pb2+, Al3+, Hg2+ and ...
-
(2012)The intracellularly-occurring Cu(I)-glutathione complex (Cu(I)-[GSH] 2) has the ability to reduce molecular oxygen into superoxide. Removal of such radicals leads to the irreversible conversion of Cu(I)-[GSH] 2 into the ...
-
(MDPI, 2017)For the first time a critical analysis of the influence that four different graphene oxide reduction methods have on the electrochemical properties of the resulting reduced graphene oxides (RGOs) is reported. Starting from ...
