Nitro radical anion formation from nitrofuryl substituted 1,4-dihydropyridine derivatives in mixed and non-aqueous media
(ELSEVIER SCIENCE SA, 2006-09)
Three new nitrofuryl substituted 1,4-dihydropyridine derivatives were electrochemically tested in the scope of newly found compounds useful as chemotherapeutic alternative to the Chagas' disease.
All the compounds were ...
Voltammetric study of nitro radical anion generated from some nitrofuran compounds of pharmacological significance
(WILEY-V C H VERLAG GMBH, 2003-01)
The electrochemical behavior of 2-(5-amino- 1,3,4-oxadiazolyl)-5-nitrofuran (NF359) and its comparison with well known drugs such as nifurtimox (NFX) and nitrofurazone (NFZ) in protic, mixed and aprotic media by cyclic ...
In search of the best DFT functional for dealing wi th organic anionic species
(Royal Society of Chemistry, 2017-01)
Quantum chemical computational methods are thought to have problems in dealing with unstable organic anions. This work assesses the ability of different Density Functional Theory (DFT) functionals to reproduce the electron ...
Electrochemical generation and reactivity of free radical redox intermediates from ortho-and meta-nitro substituted 1,4-dihydropyridines
(1997)
This paper reports a comprehensive study by cyclic voltammetry on the electrochemical characteristics and the reactivity of the one-electron reduction product from a series of nitro aryl 1,4-dihydropyridines in mixed and ...
Influence of N-Substitution on Electron Spin Resonance (ESR) Behavior of 2-(2-Nitrophenyl)-1H-benzimidazole Derivatives
(TAYLOR & FRANCIS INC., 2005)
The synthesis of 2-(2-nitrophenyl)-1H-benzimidazole (1), 1-benzoyl-2-(2-nitrophenyl)-1H -benzimidazole (2), and 1-acetyl-2-(2-nitrophenyl)-1H-benzimidazole ( 3) is reported. Stable radical anions (1(center dot-), 2(center ...
Biomimetic ketone reduction by disulfide radical anion
(Molecular Diversity Preservation International, 2021-09)
The conversion of ribonucleosides to 2′-deoxyribonucleosides is catalyzed by ribonucleoside reductase enzymes in nature. One of the key steps in this complex radical mechanism is the reduction of the 3′-ketodeoxynucleotide ...
[2.2]Paracyclophane-4,7,12,15-tetrone, [2.2](1,4)naphthalenophane-4,7,14,17-tetrone, and 1,4,8,11-pentacenetetrone radical anions - A comparative ESR study
(Wiley-VCH Verlag, 1998)
Three types of tetrone radical anions in which two 1,4-benzoquinone units are connected by ethano (1·-, 2·-), [2.2]paracyclophane (3·-, 4·-), and anthracene bridges (5·-, 6·-) have been studied by ESR and ENDOR spectroscopy. ...
Cyclic voltammetric study of the disproportionation reaction of the nitro radical anion from 4-nitroimidazole in protic media
(ELSEVIER SCIENCE, 2002-08-23)
We have chosen 4-nitroimidazole (4-NIm) as a prototype of nitroimidazolic compounds in order to carry out an exhaustive cyclic voltammetric study in protic media, 0.1 M Britton-Robinson buffer+0.3 M KCl with ethanol as a ...
Nitro radical anions from megazol and related nitroimidazoles in aprotic media. A father-son type reaction triggered by an acidic proton
(PERGAMON-ELSEVIER SCIENCE, 2002-09-25)
We have studied the electrochemical reduction of some nitroimidazoles such as megazol(2-amino-5-(1-methyl-5-nitro-2-imidazolyl)-1,3,4-thiadiazol, CAS 19622-55-0) and two related derivatives in aprotic media (100% DMF, 0.1 ...
