Compounds 1 and 2 were found to be novel 1,3-dimethyl-5-(methylthio)imidazolium alkaloids. The structure of 3 was determined to be an indole alkaloid related to hyrtioreticulin E (8) and hyrtioerectine B (9), which were isolated previously from the n-BuOH-soluble fraction of the sponge extract. The presence of three NH units in 3 was indicated by the 1H?15N HSQC spectrum in D2O/H2O (5:95) containing 0.05% TFA measured at 5 °C. Compound 3 is likely biosynthesized from l-tryptophan, two units of l-alanine, and glycine by the Pictet?Spengler reaction. The absolute configurations of 1?3 were determined by the methods based on ECD spectra. In addition, the result for 1 was further confirmed by the PGME method.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_16_publisher_36":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier","subitem_publisher_language":"en"}]},"item_16_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1016/j.tet.2013.06.043","subitem_relation_type_select":"DOI"}}]},"item_16_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"(C) 2013 This manuscript version is made available under the CC-BY-NC-ND 4.0 license http://creativecommons.org/licenses/by-nc-nd/4.0/","subitem_rights_language":"en"}]},"item_16_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0040-4020","subitem_source_identifier_type":"PISSN"}]},"item_16_subject_20":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"483.2","subitem_subject_scheme":"NDC"},{"subitem_subject":"499.3","subitem_subject_scheme":"NDC"}]},"item_16_version_type_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Imada, Kumiko","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"165247","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sakai, Eriko","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"165248","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kato, Hikaru","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"165249","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kawabata, Tetsuro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"165250","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoshinaga, Sosuke","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"165251","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nehira, Tatuso","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"165457","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Terasawa, Hiroaki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"165253","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tsukamoto, Sachiko","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"165254","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-10-23"}],"displaytype":"detail","filename":"0040-4020v69_7051-7055.pdf","filesize":[{"value":"782.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"0040-4020v69_7051-7055","url":"https://kumadai.repo.nii.ac.jp/record/31895/files/0040-4020v69_7051-7055.pdf"},"version_id":"b732ec5d-9bd4-4b85-9d8a-6c4ff76c5134"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Imidazole alkaloid","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Indole alkaloid","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Hyrtios reticulatus","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Marine sponge","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"Reticulatins A and B and hyrtioreticulin F from the marine sponge Hyrtios reticulatus","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Reticulatins A and B and hyrtioreticulin F from the marine sponge Hyrtios reticulatus","subitem_title_language":"en"}]},"item_type_id":"16","owner":"12","path":["416"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2020-10-23"},"publish_date":"2020-10-23","publish_status":"0","recid":"31895","relation_version_is_last":true,"title":["Reticulatins A and B and hyrtioreticulin F from the marine sponge Hyrtios reticulatus"],"weko_creator_id":"12","weko_shared_id":-1},"updated":"2023-10-05T04:06:02.410950+00:00"}
