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_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": "18th Annual Meeting of the Society for Free Radical Biology and Medicine (SFRBM 2011)", "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": "693841", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Inami, Keiko"}], "nameIdentifiers": [{"nameIdentifier": "693842", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Ohkubo, Kei"}], "nameIdentifiers": [{"nameIdentifier": "693843", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Kawashima, Tomonori"}], "nameIdentifiers": [{"nameIdentifier": "693844", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Fukuhara, Kiyoshi"}], "nameIdentifiers": [{"nameIdentifier": "693845", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Fukuzumi, Shunichi"}], "nameIdentifiers": [{"nameIdentifier": "693846", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Anzai, Kazunori"}], "nameIdentifiers": [{"nameIdentifier": "693847", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Ozawa, Toshihiko"}], "nameIdentifiers": [{"nameIdentifier": "693848", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Mochizuki, Masataka"}], "nameIdentifiers": [{"nameIdentifier": "693849", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Matsumoto, Kenichiro"}], "nameIdentifiers": [{"nameIdentifier": "693850", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "中西 郁夫", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "693851", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "川島 知憲", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "693852", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "松本 謙一郎", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "693853", "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": "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": "10005", "owner": "1", "path": ["28"], "permalink_uri": "https://repo.qst.go.jp/records/70639", "pubdate": {"attribute_name": "公開日", "attribute_value": "2011-11-24"}, "publish_date": "2011-11-24", "publish_status": "0", "recid": "70639", "relation": {}, "relation_version_is_last": true, "title": ["Radical-Scavenging Activity of 6-Chromanol Derivatives with Various Substituents"], "weko_shared_id": -1}
