Condensations of 2-hydroxy-6- methylthiopurine (16) with the trans-isomeric amine salt [(S)-15], its enantiomer [(R)-15], and the racemic modification [(±)-15] furnished (1'S)- , (1'R)-, and (±)-2-hydroxyl-1'-methyl-trans-zeatins (6), respectively. A similar condensation of 16 with methylamine yielded 2-hydroxy-N6- methyladenine (7). These adenine derivatives were tested for cytokinin activity in the tobacco callus bioassay, and the order of their activity was (1'R)-6>(±)-6>(1'S)-2>7; on the other hand, (1''S)-4 and (1'S)-6 were completely inactive at 0.1-100 μM and 0.01-10 μM concentrations, respectively. As a result of the above syntheses of (1'R)-6, (1'S)-6, (±)- 6, and 7, the gross structures of a marine green alga cytokinin and of a blue coral cytokinin were established to be 6 and 7, respectively.","subitem_description_type":"Abstract"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本薬学会"}]},"item_4_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1248/cpb.41.1362","subitem_relation_type_select":"DOI"}}]},"item_4_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AA00602100","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0009-2363","subitem_source_identifier_type":"ISSN"}]},"item_4_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Fujii, Tozo"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ohba, Masashi"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"Kawamura, Hitoshi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Haneishi, Tsuyoshi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Matsubara, Satoshi"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-10-03"}],"displaytype":"detail","filename":"PH-PR-OHBA-M-1362.pdf","filesize":[{"value":"959.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"PH-PR-OHBA-M-1362.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/14810/files/PH-PR-OHBA-M-1362.pdf"},"version_id":"46a7f03a-897c-407d-89bf-59e947a52b9a"}]},"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":"Purines.
