Aliaga, Margarita; Carrasco Pozo, Catalina; López Alarcón, Camilo; Olea Azar, Claudio; Speisky Cosoy, Hernán (2011)The intracellularly-occurring Cu(I)-glutathione complex (Cu(I)-[GSH](2)) has the ability to reduce molecular oxygen into superoxide radicals (O-2(center dot-)). Based on such ability, we addressed the potential of this ...

Voltammetric behavior and analytical applications of lomefloxacin, an antibacterial fluorquinolone Álvarez Lueje, Alejandro; López Alarcón, Camilo; Núñez Vergara, Luis; Squella Serrano, Juan (AOAC INTERNATIONAL, 2001-05)Lomefloxacin was reduced on a dropping mercury electrode, producing one or more peaks, depending on the pH of the aqueous medium. Coulometric measurements gave an experimental value of 1 electron for the main peak. ...
