In this study, we synthesized novel artepillin C derivatives in order to enhance the radical-scavenging activity of natural antioxidants.  The scavenging rate constants of DPPH (2,2-diphenyl-1-picrylhydrazyl) radical determined by the stopped-flow technique indicate that the introduction of the electron-donating groups on the benzene ring significantly decreases the enthalpy of the phenolic O-H bond dissociation, resulting in the enhancement of the radical-scavenging activities of the artepillin C derivatives.  There results suggested that the radical-scavenging reactions of the artepillin C derivatives proceed via one-step hydrogen atom transfer rather than proton-coupled electron transfer.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"15th Annual Meeting of the Society for Free Radical Biology and Medicine (SFRBM)","subitem_description_type":"Other"}]},"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":"Nakanishi, Ikuo"}],"nameIdentifiers":[{"nameIdentifier":"683358","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ohkubo, Kei"}],"nameIdentifiers":[{"nameIdentifier":"683359","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Uto, Yoshihiro"}],"nameIdentifiers":[{"nameIdentifier":"683360","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kawashima, Tomonori"}],"nameIdentifiers":[{"nameIdentifier":"683361","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Manda, Sushma"}],"nameIdentifiers":[{"nameIdentifier":"683362","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Fukuhara, Kiyoshi"}],"nameIdentifiers":[{"nameIdentifier":"683363","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Okuda, Haruhiro"}],"nameIdentifiers":[{"nameIdentifier":"683364","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hori, Hitoshi"}],"nameIdentifiers":[{"nameIdentifier":"683365","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ikota, Nobuo"}],"nameIdentifiers":[{"nameIdentifier":"683366","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Fukuzumi, Shunichi"}],"nameIdentifiers":[{"nameIdentifier":"683367","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ozawa, Toshihiko"}],"nameIdentifiers":[{"nameIdentifier":"683368","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Anzai, Kazunori"}],"nameIdentifiers":[{"nameIdentifier":"683369","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中西 郁夫","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"683370","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ｍａｎｄａ Ｓｕｓｈｍａ","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"683371","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小澤 俊彦","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"683372","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"安西 和紀","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"683373","nameIdentifierScheme":"WEKO"}]}]},"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":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"One-Step Hydrogen Atom Transfer in Radical-Scavenging Reactions by Artepillin C Derivatives Enhanced by Electron-Donating Groups","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"One-Step Hydrogen Atom Transfer in Radical-Scavenging Reactions by Artepillin C Derivatives Enhanced by Electron-Donating Groups"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-12-01"},"publish_date":"2008-12-01","publish_status":"0","recid":"69614","relation_version_is_last":true,"title":["One-Step Hydrogen Atom Transfer in Radical-Scavenging Reactions by Artepillin C Derivatives Enhanced by Electron-Donating Groups"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:12:25.544861+00:00"}
