    • Mechanisms underlying the inhibition of the cytochrome P450 system by copper ions 
      Letelier, M. E.; Faúndez, M.; Jara Sandoval, José; Molina Berríos, Alfredo Enrique; Cortés Troncoso, Juan; Aracena Parks, Paula; Marín Catalán, Rigoberto (2009)
      Copper toxicity has been associated to the capacity of free copper ions to catalyze the production of superoxide anion and hydroxyl radical, reactive species that modify the structure and/or function of biomolecules. In ...
    • NADPH oxidase activity: Spectrophotometric determination of superoxide using pyrogallol red 
      Cortés-Ríos, J.; Torres, M. J.; Campos-Bustamante, M. P.; Romero-Parra, J.; Letelier, M. E.; Pessoa-Mahana, D.; Chung, H.; Faúndez, M. (Academic Press Inc., 2017)
      © 2017 Elsevier Inc.A simple and fast spectrophotometric methodology able to quantify superoxide released by NADPH oxidase from differentiated promyelocytic leukaemia (HL-60) cells using pyrogallol red is described.The ...
    • Pyrogallol red oxidation induced by superoxide radicals: Application to evaluate redox cycling of nitro compounds 
      Faúndez, M.; Rojas, M.; Bohle, P.; Reyes, C.; Letelier, M. E.; Aliaga, M. E.; Speisky Cosoy, Hernán; Lissi Gervaso, Eduardo A.; López Alarcón, Camilo (2011)
      The bleaching of the pyrogallol red (PGR) dye mediated by superoxide anion radicals (O2-) generated from the xanthine/xanthine oxidase system (X/XO) was studied by UV-visible spectrophotometry. The absorption band (at 540 ...
