Cyclic voltammetric determination of free radical species from nitroimidazopyran: a new antituberculosis agent
(ELSEVIER SCIENCE, 2004-01-15)
PA-824 (2-nitro-6-(4-trifluoromethoxy-benzyloxy)-6,7-dihydro-5H-imidazo[2,1-b][1,3]oxazine) is being tested as antituberculosis drug. Little is known on the action mechanism of PA-824; however the reduction of the nitro ...
Cyclic voltammetric studies on nitro radical anion formation from megazol and some related nitroimidazole derivatives
(ELSEVIER SCIENCE, 2001-09-21)
Megazol (2-amino-5-(1-methyl-5-nitro-2-imdazolyl)-1,3,4-thiadiazol, CAS 19622-55-0) and related nitroimidazole compounds are being tested as antichagasic drugs. Little is known on the mode of action of megazol. However, ...
Generation of Naphthoquinone Radical Anions by Electrospray Ionization: Solution, Gas-Phase, and Computational Chemistry Studies
(AMER CHEMICAL SOC, 2011)
Radical anions are present in several chemical processes, and understanding the reactivity of these species may be described by their thermodynamic properties. Over the last years, the formation of radical ions in the gas ...
Combined experimental and theoretical studies on the radical nucleophile addition reaction for Sulfide- and Selenide-Centered Anions
(American Chemical Society, 2019-06)
The reactivity of sulfur- and selenium-centered nucleophiles toward 1-naphthyl radicals was studied in dimethylsulfoxide. The photostimulated reaction of sulfide anions, -SC(NH)C6H5 (1), -SC(NH)NH2 (2), and -SC(NH)CH3 (3), ...
Electrochemical approach to the radical anion formation from 2 '-hydroxy chalcone derivatives
(WILEY-V C H VERLAG GMBH, 2006-03)
Three 2'-hydroxy chalcone derivatives were electrochemically reduced to the radical anion by a reversible one-electron transfer followed by a chemical dimerization reaction. Under suitable conditions of the medium, the ...
Nitro radical anion formation from nitro‐substituted amphetamine derivatives
(1994)
The cyclic voltammetric characteristics of two nitroamphetamine derivatives (2‐nitro‐4,5‐dimethoxyamphetamine and 2‐nitro‐4,5‐methylenedioxyamphetamine) have been investigated in different media. In mixed media (aqueous ...
Nitro radical anion formation from nifurtimox II: electrochemical evidence
(Elsevier, 1995)
The cyclic voltammetric (CV) behaviour of nifurtimox was studied. The addition of aprotic solvent (DMF) to nifurtimox in an aqueous citrate buffer system was examined. Qualitatively this results in separation of the initial ...
