In this presentation, 4-hydroxyl-2,2,6,6-tetramethylpiperidine-N-oxyl (TEMPOL) and 3-carbamoyl-2,2,5,5-tetramethylpyrrolidine-N-oxyl (carbamoyl-PROXYL) were tested as typical 6-memberd ring and 5-memberd ring nitroxyl compounds. Two free radical species of ROS, i.e. hydroxyl radical (•OH) and superoxide (O2•-), were also subjected to an examination. The •OH was observed by UV irradiation to a H2O2 aqueous solution. The O2•- was obtained by a hypoxanthine-xanthine oxidase (HX-XO) reactive system. The molecular amount of ROS generated was quantified by electron spin resonance (EPR) spin-trapping method using 5-(2,2-dimethyl-1,3-propoxycyclophosphoryl)-5-methyl-1-pyrroline-N-oxide (CYPMPO) as the spin-trapping agent. Amount of •OH generation by H2O2-UV reaction system and amount of O2•- generation by HX-XO system were adjusted to become the same amount. O2•- was react with TEMPOL relatively easier compared to carbamoyl-PROXYL. TEMPOL has more reactive with O2•- than •OH, while carbamoyl-PROXYL was much reactive with •OH than O2•-. TEMPOL-H, which is the hydroxyl amine form of TEMPOL, was slightly more reactive with •OH then O2•-. Carbamoyl-PROXYL-H, the hydroxyl amine form of carbamoyl-PROXYL, has the similar reactivity with O2•- or with •OH.","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":"1st QST International Symposium -Quantum Life Science-","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":"Kamibayashi, Masato"}],"nameIdentifiers":[{"nameIdentifier":"713270","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nyui, Minako"}],"nameIdentifiers":[{"nameIdentifier":"713271","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakanishi, Ikuo"}],"nameIdentifiers":[{"nameIdentifier":"713272","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Anzai, Kazunori"}],"nameIdentifiers":[{"nameIdentifier":"713273","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ozawa, Toshihiko"}],"nameIdentifiers":[{"nameIdentifier":"713274","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Matsumoto, Ken-ichiro"}],"nameIdentifiers":[{"nameIdentifier":"713275","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"上林 將人","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"713276","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"乳井 美奈子","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"713277","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中西 郁夫","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"713278","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"安西 和紀","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"713279","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小澤 俊彦","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"713280","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"松本 謙一郎","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"713281","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":"Comparison of Reactivity of Nitroxyl Free Radicals and Reactive Oxygen Species","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Comparison of Reactivity of Nitroxyl Free Radicals and Reactive Oxygen Species"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-08-14"},"publish_date":"2017-08-14","publish_status":"0","recid":"72413","relation_version_is_last":true,"title":["Comparison of Reactivity of Nitroxyl Free Radicals and Reactive Oxygen Species"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:40:06.638343+00:00"}
