Thus, the prevention of mitochondrial oxidative damage is nowadays a recognized pharmacological strategy to delay disease progression. Epidemiological studies suggested an association between the consumption of polyphenol-rich diet and the prevention of different pathologies, including diseases with a mitochondrial etiology. The development of mitochondrial-targeted antioxidants based on dietary antioxidants may decrease mitochondrial oxidative damage. Herein, we report the design and synthesis of two new mitochondriotropic antioxidants based on hydroxybenzoic acids (AntiOxBENs). The results obtained showed that the novel antioxidants are accumulated inside rat liver mitochondria driven by the organelle transmembrane electric potential and prevented lipid peroxidation, exhibiting low toxicity. Some of the observed effects on mitochondrial bioenergetics resulted from an increase of proton leakage through the mitochondrial inner membrane. The new derivatives present a higher lipophilicity than the parent compounds (protocatechuic and gallic acids) and similar antioxidant and iron chelating properties. AntiOxBENs are valid mitochondriotropic antioxidant prototypes, which can be optimized and used in a next future as drug candidates to prevent or slow mitochondrial oxidative stress associated to several pathologies.<\/jats:p>","DOI":"10.1038\/s41598-017-07272-y","type":"journal-article","created":{"date-parts":[[2017,7,24]],"date-time":"2017-07-24T15:08:54Z","timestamp":1500908934000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":44,"title":["Development of hydroxybenzoic-based platforms as a solution to deliver dietary antioxidants to mitochondria"],"prefix":"10.1038","volume":"7","author":[{"given":"Jos\u00e9","family":"Teixeira","sequence":"first","affiliation":[]},{"given":"Catarina","family":"Oliveira","sequence":"additional","affiliation":[]},{"given":"Ricardo","family":"Amorim","sequence":"additional","affiliation":[]},{"given":"Fernando","family":"Cagide","sequence":"additional","affiliation":[]},{"given":"Jorge","family":"Garrido","sequence":"additional","affiliation":[]},{"given":"Jos\u00e9 A.","family":"Ribeiro","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8392-9581","authenticated-orcid":false,"given":"Carlos M.","family":"Pereira","sequence":"additional","affiliation":[]},{"given":"Ant\u00f3nio F.","family":"Silva","sequence":"additional","affiliation":[]},{"given":"Paula B.","family":"Andrade","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5201-9948","authenticated-orcid":false,"given":"Paulo J.","family":"Oliveira","sequence":"additional","affiliation":[]},{"given":"Fernanda","family":"Borges","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2017,7,28]]},"reference":[{"key":"7272_CR1","doi-asserted-by":"publisher","first-page":"288","DOI":"10.1016\/j.foodchem.2010.08.012","volume":"125","author":"M Leopoldini","year":"2011","unstructured":"Leopoldini, M., Russo, N. & Toscano, M.
