Although 28 methanol extracts inhibited RTase more than 70 % at a concentration of 100 μg/ml, only 3 samples, T42 (藏青果, Termlnalia chebula RETZ.), T46 (檳榔, Areca catechu L.) and T61 (紅檳榔), were found still inhibitory after eliminating the effect of tannins by addition of BSA in the enzyme reaction mixture. In the case of the RdRp, 7 extracts with IC_<50> values of less than 10 μg/ml contained less than 20 % tannins. The extract of Rhodiola sacra, whose IC_<50> for RTase was 25.9 μg/ml, was subject to phytochemical investigation. Out of 8 compounds isolated from the extract, daucosterol was found effective for RTase.","subitem_description_type":"Abstract"}]},"item_4_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学医薬保健研究域薬学系","subitem_description_type":"Other"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Medical and Pharmaceutical Society for WAKAN-YAKU = 和漢医薬学会"}]},"item_4_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ci.nii.ac.jp/naid/110001846611/en/","subitem_relation_type_select":"URI"}}]},"item_4_rights_23":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"本文データは和漢医薬学会の許諾に基づきCiNiiから複製したものである"}]},"item_4_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AA12035198","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1880-1447","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":"Kimura, Takako"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Jyo, Michiko"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nakamura, Norio"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Komatsu, Katsuko"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hattori, Masao"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Shimotohno, Kumiko"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Shimotohno, Kunitada"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kakiuchi, Nobuko"}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-10-04"}],"displaytype":"detail","filename":"PH-PR-KAKIUCHI-N-243.pdf","filesize":[{"value":"732.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"PH-PR-KAKIUCHI-N-243.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/15278/files/PH-PR-KAKIUCHI-N-243.pdf"},"version_id":"9055b7c7-1369-444f-9cb9-4443ad55085c"}]},"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":"Inhibitory effect of Tibetan medicinal plants on viral polymerases","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Inhibitory effect of Tibetan medicinal plants on viral polymerases"}]},"item_type_id":"4","owner":"3","path":["1135"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-04"},"publish_date":"2017-10-04","publish_status":"0","recid":"15278","relation_version_is_last":true,"title":["Inhibitory effect of Tibetan medicinal plants on viral polymerases"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-27T09:47:34.567140+00:00"}
