The quasi-reversible cyclic voltammogram of dioxygen/O2•– was modified by the presence of trans-resveratrol, suggesting that the electrogenerated O2•– was scavenged by trans-resveratrol through proton-coupled electron transfer (PCET) via three phenolic hydroxy groups (OH) on the stilbene moiety. The reactivity of trans-resveratrol toward O2•– characterized by the OHs was experimentally confirmed in comparative analyses using some related compounds, pinosylvin, pterostilbene, p-coumaric acid, and so on, in DMF. The electrochemical and DFT results suggested that a concerted PCET mechanism via 4′OH of trans-resveratrol proceeds, where the coplanarity of the two phenolic rings in the stilbene moiety linked by an ethylene bridge is essential for a successful O2•– scavenging.","subitem_description_type":"Abstract"}]},"item_10004_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"american chemical society"}]},"item_10004_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1021/acs.jafc.2c08105","subitem_relation_type_select":"DOI"}}]},"item_10004_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0021-8561","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"nakayama, tatsushi"}],"nameIdentifiers":[{"nameIdentifier":"32440","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"N000638361","nameIdentifierScheme":"CiNii ID","nameIdentifierURI":"http://ci.nii.ac.jp/nrid/N000638361"}]},{"creatorNames":[{"creatorName":"Uno, Bunji"}],"nameIdentifiers":[{"nameIdentifier":"36620","nameIdentifierScheme":"WEKO"}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"resveratrol","subitem_subject_scheme":"Other"},{"subitem_subject":"superoxide","subitem_subject_scheme":"Other"},{"subitem_subject":"electrochemistry","subitem_subject_scheme":"Other"},{"subitem_subject":"density functional theory","subitem_subject_scheme":"Other"},{"subitem_subject":"proton-coupled electron transfer","subitem_subject_scheme":"Other"},{"subitem_subject":"resveratrol","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"superoxide","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"electrochemistry","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"density functional theory","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"proton-coupled electron transfer","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Reactivity of trans-Resveratrol toward Electrogenerated Superoxide in N,N-Dimethylformamide","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Reactivity of trans-Resveratrol toward Electrogenerated Superoxide in N,N-Dimethylformamide"},{"subitem_title":"Reactivity of trans-Resveratrol toward Electrogenerated Superoxide in N,N-Dimethylformamide","subitem_title_language":"en"}]},"item_type_id":"10004","owner":"140","path":["345"],"pubdate":{"attribute_name":"公開日","attribute_value":"2023-03-20"},"publish_date":"2023-03-20","publish_status":"0","recid":"14855","relation_version_is_last":true,"title":["Reactivity of trans-Resveratrol toward Electrogenerated Superoxide in N,N-Dimethylformamide"],"weko_creator_id":"140","weko_shared_id":-1},"updated":"2023-06-19T07:38:42.764164+00:00"}
