Preparation of [11C]iomazenil with\n[11C]CH3I produced a good radiochemical yield, however,\nits radiochemical purity was always less than 90% without\nadditives. This poor radiochemical purity was attributed to radiolysis\nof [11C]iomazenil. The degradation of [11C]iomazenil\nvia radiolysis was markedly facilitated in the presence of\nHCOONa (strong selective hydroxyl radical and hydrogen\natom scavenger). On the other hand, the radiolysis was\nsuppressed effectively in the presence of NaNO3 (selective\nhydrated electron scavenger), suggesting participation of hydrated\nelectrons in the radiolysis of [11C]iomazenil. LC/MS\nanalysis of the degradation product suggested that the major\ndegradation product by radiolysis had a molecular weight of\n285 corresponding to the deiodinated compound. The present\nstudy showed that a decrease in the radiochemical purity\nof [11C]iomazenil was attributed to the radiolysis via the\ndeiodination reaction by hydrated electron.","subitem_description_type":"Abstract"}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0033-8230","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":"Fukumura, Toshimitsu"}],"nameIdentifiers":[{"nameIdentifier":"478579","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamaguchi, Masatoshi"}],"nameIdentifiers":[{"nameIdentifier":"478580","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Suzuki, Kazutoshi"}],"nameIdentifiers":[{"nameIdentifier":"478581","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"福村 利光","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"478582","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"山口 政俊","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"478583","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鈴木 和年","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"478584","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Radiolysis of an aqueous [11C]iomazenil solution","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Radiolysis of an aqueous [11C]iomazenil solution"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-03-27"},"publish_date":"2017-03-27","publish_status":"0","recid":"47695","relation_version_is_last":true,"title":["Radiolysis of an aqueous [11C]iomazenil solution"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:36:35.218690+00:00"}
