When the phytyl group at the C2 position in alpha-tocopherol was replaced by methyl group, no significant change was observed [k = 3.2 x 10(3) M(-1) s(-1)].  On the other hand, a carboxyl group at the C2 position significantly retarded the GO-scavenging rate [k = 4.9 x 10(2) M(-1) s(-1)].  Among the 6-chromanol derivatives, 8-amino-2,2-dimethylchroman-6-ol showed the highest GO-scavenging activity [k = 1.4 x 10(4) M(-1) s(-1)].  The smaller the calculated ionization potential by the density functional theory is, the stronger the GO-scavenging activity becomes.","subitem_description_type":"Abstract"}]},"item_10003_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0891-5849","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":"Nakanishi, Ikuo"}],"nameIdentifiers":[{"nameIdentifier":"554648","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Inami, Keiko"}],"nameIdentifiers":[{"nameIdentifier":"554649","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ohkubo, Kei"}],"nameIdentifiers":[{"nameIdentifier":"554650","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kawashima, Tomonori"}],"nameIdentifiers":[{"nameIdentifier":"554651","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Fukuhara, Kiyoshi"}],"nameIdentifiers":[{"nameIdentifier":"554652","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Fukuzumi, Shunichi"}],"nameIdentifiers":[{"nameIdentifier":"554653","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Anzai, Kazunori"}],"nameIdentifiers":[{"nameIdentifier":"554654","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ozawa, Toshihiko"}],"nameIdentifiers":[{"nameIdentifier":"554655","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Mochizuki, Masataka"}],"nameIdentifiers":[{"nameIdentifier":"554656","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Matsumoto, Kenichiro"}],"nameIdentifiers":[{"nameIdentifier":"554657","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中西 郁夫","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"554658","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"川島 知憲","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"554659","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"松本 謙一郎","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"554660","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 paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"Radical-Scavenging Activity of 6-Chromanol Derivatives with Various Substituents","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Radical-Scavenging Activity of 6-Chromanol Derivatives with Various Substituents"}]},"item_type_id":"10003","owner":"1","path":["2"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-11-24"},"publish_date":"2011-11-24","publish_status":"0","recid":"54302","relation_version_is_last":true,"title":["Radical-Scavenging Activity of 6-Chromanol Derivatives with Various Substituents"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:02:32.612915+00:00"}
