Current drug design in the field is partially based on specific modifications of the known Se-therapeutics aimed at achieving more selective bioactivity towards particular drug targets, accompanied by low toxicity as the therapeutic window for organoselenium compounds tends to be very narrow. Herein, we present a new group of Se-based antioxidants, structurally derived from the well-known group of GPx mimics\u2014benzisoselenazol-3(2H)-ones. A series of N-substituted unsymmetrical phenylselenides with an o-amido function has been obtained by a newly developed procedure: a copper-catalyzed nucleophilic substitution by a Se-reagent formed in situ from diphenyl diselenide and sodium borohydride. All derivatives were tested as antioxidants and anticancer agents towards breast (MCF-7) and leukemia (HL-60) cancer cell lines. The highest H2O2-scavenging potential was observed for N-(3-methylbutyl)-2-(phenylselanyl)benzamide. The best antiproliferative activity was found for (\u2212)-N-(1S,2R,4R)-menthyl-2-(phenylselanyl)benzamide (HL-60) and ((\u2212)-N-(1S,2R,3S,6R)-(2-caranyl))benzamide (MCF-7). The structure\u2013activity correlations, including the differences in reactivity of the obtained phenyl selenides and corresponding benzisoselenazol-3(2H)-ones, were performed.<\/jats:p>","DOI":"10.3390\/molecules25153354","type":"journal-article","created":{"date-parts":[[2020,7,24]],"date-time":"2020-07-24T09:19:27Z","timestamp":1595582367000},"page":"3354","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Phenylselanyl Group Incorporation for \u201cGlutathione Peroxidase-Like\u201d Activity Modulation"],"prefix":"10.3390","volume":"25","author":[{"given":"Magdalena","family":"Obieziurska-Fabisiak","sequence":"first","affiliation":[{"name":"Department of Organic Chemistry, Faculty of Chemistry, Nicolaus Copernicus University, 7 Gagarin Street, 87-100 Torun, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Agata J.","family":"Pacu\u0142a","sequence":"additional","affiliation":[{"name":"Department of Organic Chemistry, Faculty of Chemistry, Nicolaus Copernicus University, 7 Gagarin Street, 87-100 Torun, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lucia","family":"Capoccia","sequence":"additional","affiliation":[{"name":"Dipartimento di Scienze Farmaceutiche, Universita di Perugia, Via del Liceo 1, 06134 Perugia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joanna","family":"Drogosz-Stachowicz","sequence":"additional","affiliation":[{"name":"Department of Biomolecular Chemistry, Faculty of Medicine, Medical University of Lodz, Mazowiecka 6\/8, 92-215 Lodz, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna","family":"Janecka","sequence":"additional","affiliation":[{"name":"Department of Biomolecular Chemistry, Faculty of Medicine, Medical University of Lodz, Mazowiecka 6\/8, 92-215 Lodz, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7698-8970","authenticated-orcid":false,"given":"Claudio","family":"Santi","sequence":"additional","affiliation":[{"name":"Dipartimento di Scienze Farmaceutiche, Universita di Perugia, Via del Liceo 1, 06134 Perugia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3868-2022","authenticated-orcid":false,"given":"Jacek","family":"\u015acianowski","sequence":"additional","affiliation":[{"name":"Department of Organic Chemistry, Faculty of Chemistry, Nicolaus Copernicus University, 7 Gagarin Street, 87-100 Torun, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,7,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"395","DOI":"10.3389\/fphar.2018.00395","article-title":"Aromatic Rings Commonly Used in Medicinal Chemistry: Force Fields Comparison and Interactions with Water Toward the Design of New Chemical Entities","volume":"9","author":"Rusu","year":"2018","journal-title":"Front.
