Under adequate conditions, yields of about 38% in the case of free base and about 63% in the case of ribofuranosyl derivative have been obtained. The latter compound has also been prepared in a non-carrier-added state. The stability of 18F-purines was examined in Tris buffer at 37 Degree.","subitem_description_type":"Abstract"}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0020-708X","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":"Irie, Toshiaki"}],"nameIdentifiers":[{"nameIdentifier":"441653","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Fukushi, Kiyoshi"}],"nameIdentifiers":[{"nameIdentifier":"441654","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ido, Tatsuo"}],"nameIdentifiers":[{"nameIdentifier":"441655","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"入江 俊章","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"441656","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"福士 清","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"441657","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":"Synthesis of 18F-6-fluoropurine and 18F-6-fluoro-9-beta-D-ribofuranosylpurine","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Synthesis of 18F-6-fluoropurine and 18F-6-fluoro-9-beta-D-ribofuranosylpurine"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2006-07-07"},"publish_date":"2006-07-07","publish_status":"0","recid":"44441","relation_version_is_last":true,"title":["Synthesis of 18F-6-fluoropurine and 18F-6-fluoro-9-beta-D-ribofuranosylpurine"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-16T00:15:25.572403+00:00"}
