They absorb heavy metal ions and other pollutants from the environments and are thus regarded as an important biological monitor of pollution. The present study aimed at elucidating the complex formation between the beta-triketone moiety of a typical lichen substance usnic acid (UA) or its derivatives and various heavy metal ions by synthetic, spectroscopic, and X-ray diffraction methods.\nThe copper (II) and palladium (II) complexes of UA and the palladium (II) complexes of the enamine derivatives of UA were isolated as crystals. The metal binding sites have been inferred from various spectral data and confirmed by the X-ray structural analysis of the ternary copper (II) complexes containing UA and 2,2'-bipyridine (bpy), [Cu (bpy)(UA)(No_3)] and [Cu_2 (bpy)_2 (UA)-(NO_3) _2], and two binary palladium (II) complexes of the enamine derivatives of UA.From the pH dependence of the copper (II) complex formation of UA,the complex was found to be completely formed at pH>7. The binary UA complexes of Fe (III), Zn (II), Pb (II), Cd (II), Ni (II), Mn (II), Mg (II), and Ca (II) were prepared, and their metal binding site has been conclcuded to be beta-triketone moiety.\nScince lichens contain UA and similar polyphenol compounds, the present findings strongly indicate that they can bind a number of metal ions and serve as an effecient biological monitor of air and water pollution.\nAs a further example of the complex formation of natural organic compounds, indole-3-acetate, which is known as a plant hormone, has been established to react with palladium (II) to from a complex with a unique cyclopalladation.","subitem_description_type":"Abstract"}]},"item_9_description_22":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究課題/領域番号:06640719, 研究期間(年度):1994 – 1995","subitem_description_type":"Other"},{"subitem_description":"出典：研究課題「環境モニター天然有機化合物の金属捕捉能の錯体化学的研究」課題番号06640719\n（KAKEN：科学研究費助成事業データベース（国立情報学研究所）） \n（https://kaken.nii.ac.jp/ja/report/KAKENHI-PROJECT-06640719/066407191995kenkyu_seika_hokoku_gaiyo/）を加工して作成","subitem_description_type":"Other"}]},"item_9_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学薬学部","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00066407","subitem_identifier_reg_type":"JaLC"}]},"item_9_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/search/?qm=40019667"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/search/?qm=40019667","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/grant/KAKENHI-PROJECT-06640719/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/grant/KAKENHI-PROJECT-06640719/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/report/KAKENHI-PROJECT-06640719/066407191995kenkyu_seika_hokoku_gaiyo/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/report/KAKENHI-PROJECT-06640719/066407191995kenkyu_seika_hokoku_gaiyo/","subitem_relation_type_select":"URI"}}]},"item_9_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-06-17"}],"displaytype":"detail","filename":"PH-PR-TAKANI-M-kaken 1997-2p.pdf","filesize":[{"value":"76.1 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"PH-PR-TAKANI-M-kaken 1997-2p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/60156/files/PH-PR-TAKANI-M-kaken 1997-2p.pdf"},"version_id":"a611af24-4d82-4fc0-9f12-50ee0f61cbc9"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"環境モニター天然有機化合物の金属捕捉能の錯体化学的研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"環境モニター天然有機化合物の金属捕捉能の錯体化学的研究"},{"subitem_title":"Studies on the Chemistry of Metal Ion Binding by Natural Products as Environmental Monitors","subitem_title_language":"en"}]},"item_type_id":"9","owner":"18","path":["2838"],"pubdate":{"attribute_name":"公開日","attribute_value":"2022-06-17"},"publish_date":"2022-06-17","publish_status":"0","recid":"60156","relation_version_is_last":true,"title":["環境モニター天然有機化合物の金属捕捉能の錯体化学的研究"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-07-27T12:51:09.633851+00:00"}
