Journal ArticleDOI
S-allylmercaptocysteine scavenges hydroxyl radical and singlet oxygen in vitro and attenuates gentamicin-induced oxidative and nitrosative stress and renal damage in vivo
José Pedraza-Chaverri,Diana Barrera,Perla D. Maldonado,Yolanda I. Chirino,Norma A. Macías-Ruvalcaba,Omar Noel Medina-Campos,Leticia Castro,Marcos I Salcedo,Rogelio Hernández-Pando +8 more
TL;DR: S-allylmercaptocysteine is able to scavenge hydroxyl radicals and singlet oxygen in vitro and to ameliorate the gentamicin-induced nephrotoxicity and oxidative and nitrosative stress in vivo.
Journal ArticleDOI
An Experimental and Theoretical Study of the Substituent Effects on the Redox Properties of 2-[(R-phenyl)amine]-1,4-naphthalenediones in Acetonitrile.

TL;DR: The theoretical calculations predict that, with the exception of the p-nitro compound, all the compounds are planar molecules where the conjugation degree of the nitrogen lone pair with the quinone system depends on the position and magnitude of the electronic effect of the substituent in the aniline ring.
Journal ArticleDOI
Study of the Effects of Ion Pairing and Activity Coefficients on the Separation in Standard Potentials for Two-Step Reduction of Dinitroaromatics
TL;DR: It is concluded that structural changes accompanying the reduction, rather than activity and ion pairing effects, are the dominant factors underlying potential inversion.
Journal ArticleDOI
Mechanism of the OH radical scavenging activity of nordihydroguaiaretic acid: a combined theoretical and experimental study
TL;DR: It is found that NDGA protects, in a concentration-dependent way, bovine serum albumin and DNA from the damage induced by (*)OH generated by the Fenton reaction.
Journal ArticleDOI
Time course study of oxidative and nitrosative stress and antioxidant enzymes in K2Cr2O7-induced nephrotoxicity
José Pedraza-Chaverri,Diana Barrera,Omar Noel Medina-Campos,Raymundo C Carvajal,Rogelio Hernández-Pando,Norma A. Macías-Ruvalcaba,Perla D. Maldonado,Marcos I Salcedo,Edilia Tapia,Liliana Saldívar,María E Castilla,María Elena Ibarra-Rubio +11 more
TL;DR: Renal antioxidant enzymes were regulated differentially and were not closely associated with oxidative or nitrosative stress or with kidney damage, suggesting that nitric oxide was derived to the formation of reactive nitrogen species involved in protein nitration.
