Fecha de publicación: | 16-sep-2023 | Editor: | Multidisciplinary Digital Publishing Institute | Citación: | Processes 11(9): 2771 (2023) | Resumen: | In this review, we have focused mainly on the study of their antioxidant and pro-oxidant capacity, and the analysis of the oxidation of the catechol group to o-quinone. The redox balance established between the different oxidase and reductase enzymes generates reducing species, H+ and e−, and allows the oxidation of polyphenolic groups to quinones to be reversible. This continuous balance between these nucleophilic and electrophilic substances allows the activation of the NRF2/ARE axis, which regulates cellular antioxidant responses against oxidative stress, as well as cell proliferation. Understanding the ambivalent character of polyphenols, which can act simultaneously as antioxidants and pro-oxidants, will allow the design of specific therapies that can serve science and medicine in their tasks. | Versión del editor: | https://doi.org/10.3390/pr11092771 | URI: | http://hdl.handle.net/10261/336462 | DOI: | 10.3390/pr11092771 | E-ISSN: | 2227-9717 |
