However, delayed blood clearance and high gastric uptake of radioactivity have been observed upon injection, due to the instability of 186Re-HEDP. We designed, synthesized and evaluated a stable 186Re-mercaptoacetylglycylglycylglycine (MAG3) complex-conjugated bisphosphonate, [[[[(4-hydroxy-4,4-diphosphonobutyl)carbamoylmethyl] carbamoylmethyl]carbamoylmethyl]carbamoylmethanethiolate] oxorhenium(V) ( 186Re-MAG3-HBP). The stability of 186Re-MAG3-HBP and 186Re-HEDP in phosphate buffer were compared. No measurable decomposition of 186Re- MAG3-HBP occurred, while only approximately 30% of 186Re-HEDP remained intact 24 hours post-incubation. In biodistribution experiments, the radioactivity level of 186Re-MAG3-HBP in bone was significantly higher than that of 186Re- HEDP. Blood clearance of 186Re-MAG3-HBP was faster than that of 186Re-HEDP. In addition, the gastric accumulation of 186Re-MAG3-HBP radioactivity was lower. To evaluate the therapeutic effects of 186Re-MAG3-HBP, an animal model of bone metastasis was prepared. In the rats treated with 186Re-HEDP, tumor growth was comparable to that in untreated rats. In contrast, when 186Re-MAG3-HBP was administered, tumor growth was significantly inhibited. Bone pain was attenuated by treatment with 186Re-MAG3-HBP or 186Re-HEDP, but 186Re-MAG3-HBP tended to be more effective. These results indicate that 186Re-MAG3-HBP could be useful as a therapeutic agent of metastatic bone pain. Moreover, based on the similar concept, we designed, synthesized, and evaluated a 99mTc-6-hydrazinopyridine-3-carboxylic acid-conjugated bisphosphonate ( 99mTc-HYNIC-HBP) as a bone scintigraphic agent. 99mTc-HYNIC-HBP gave higher levels of radioactivity in bone than 99mTc-HMDP. There was no significant difference in clearance from blood between 99mTc-HYNIC-HBP and 99mTc-HMDP. Consequently, 99mTc-HYNIC-HBP showed a higher bone-to-blood ratio than 99mTc-HMDP. The findings indicate that 99mTc-HYNIC-HBP holds great potential for bone scintigraphy. © 2012 The Pharmaceutical Society of Japan.","subitem_description_type":"Abstract"}]},"item_4_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学新学術創成研究機構","subitem_description_type":"Other"}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00015052","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Pharmaceutical Society of Japan = 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/yakushi.12-00218","subitem_relation_type_select":"DOI"}}]},"item_4_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AN00284903","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0031-6903","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":"小川, 数馬"}],"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-OGAWA-K-1151.pdf","filesize":[{"value":"721.8 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"PH-PR-OGAWA-K-1151.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/15065/files/PH-PR-OGAWA-K-1151.pdf"},"version_id":"46a61777-04b8-48cd-a615-a64ea0138f9e"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"転移性骨腫瘍の核医学診断・治療を目的とした薬剤の開発研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"転移性骨腫瘍の核医学診断・治療を目的とした薬剤の開発研究"},{"subitem_title":"Development of radiopharmaceuticals for diagnosis and therapy of metastatic bone cancer","subitem_title_language":"en"}]},"item_type_id":"4","owner":"3","path":["2270"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-04"},"publish_date":"2017-10-04","publish_status":"0","recid":"15065","relation_version_is_last":true,"title":["転移性骨腫瘍の核医学診断・治療を目的とした薬剤の開発研究"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-27T10:13:46.210449+00:00"}
