A nitro radical anion formation from nifedipine: an electrochemical approach
(1993)
The cyclic voltammetric behaviour of nifedipine was studied. The addition of three aprotic solvents to nifedipine in an aqueous citrate buffer system was examined. Qualitatively they result in separation of the initial ...
Redox behaviour of nifuroxazide: Generation of the one-electron reduction product
(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. ...
Electrochemical, UV-visible and EPR studies on nitrofurantoin: Nitro radical anion generation and its interaction with glutathione
(HARWOOD ACAD PUBL GMBH, 2000)
This paper deals with the reactivity of the nitro radical anion electrochemically generated from nitrofurantoin with glutathione. Cyclic voltammetry (CV) and controlled potential electrolysis were used to generate the nitro ...
Study of the Electronic delocalization in Silicon organic derivatives of benzene and their corresponding anion radicals
(Universidad Autónoma de Occidente, 2006-01)
The silicon organic compounds phenyltrimethylsilane (1), 1,4-bis(trimethylsilyl)benzene
(2), diphenyldimethylsilane (3) y 1,1,2,2-dibenzobis(dimethyls ilane) (4) were synthesized and characterized by IR, NMR-1 H and elemental ...
Electrochemical reduction of 2,5-dimethoxy nitrobenzenes: nitro radical anion generation and biological activity
(ELSEVIER SCIENCE, 1998-08)
The electrochemical reduction of four 2,5-dimethoxy nitrobenzene 6-substituted derivatives in aqueous and mixed media by cyclic voltammetry, tast and differential pulse polarography were studied. In aqueous media, pH > 8, ...
An Electron Spin Resonance (ESR) investigation of potential ligands of inorganic interest with nitro substituents
(MARCEL DEKKER INC, 2002)
Electron Spin Resonance spectra were obtained of the salicyliden-2-imino-5-nitropyrimidine (1(.-)), N,N-bis(5-nitro-salicyliden). ethylendiamine (2(.-)), 2-hydroxy-5-nitro-benziliden-5-iminoquinoline (3(.-)) anion I radicals ...
Scavenging of the one-electron reduction product from nisoldipine with relevant thiols: Electrochemical and EPR spectroscopic evidences
(1998)
Purpose. To determine the formation of the one-electron reduction product from nisoldipine and its reactivity with relevant thiols in mixed medium. Methods. Cyclic voltammetry (CV) and electron paramagnetic resonance (EPR) ...
Electrochemistry and Reactivity against Superoxide Anion Radicals of Hydroxycoumarins and Its Derivatives
(IOP Publishing Ltd, 2020-12-10)
The present studies reveal superoxide radical anion reactivity against synthesized coumarins. Free radicals play an important role in many diseases and they have a protective function also. Therefore, we must keep a balance ...
Competitive reaction pathways for o-Anilide aryl radicals: 1,5-Or 1,6-hydrogen transfer versus nucleophilic coupling reactions. A novel rearrangement to afford an amidyl Radical
(American Chemical Society, 2009-02)
The photoinduced reactions of o-iodoanilides (o-IC6H 4N(Me)COR, 4a-d) with sulfur nucleophiles such as thiourea anion (1, -SCNH(NH2)), thioacetate anion (2, MeCOS-), and sulfide anion (3,S2-) follow different reaction ...
An electrochemical evidence of free radicals formation from flutamide and its reactivity with endo/xenobiotics of pharmacological relevance
(ELSEVIER SCIENCE, 2001-01)
This paper reports the feasibility of free radicals formation from flutamide by using cyclic voltammetry. The electrochemical characteristics and the reactivity of the one-electron reduction product from flutamide in mixed ...
