Our results showed that BH formation was significantly inhibited by basic amino acids (arginine, lysine, and histidine), probably due to the abilities of these amino acids to complex with heme. The results suggest an involvement in the improvement of the blood-schizonticidal activity of 8-quinolinamine when conjugated with basic amino acids. In addition, cysteine also inhibited BH formation, possibly due to its ability to reduce heme iron or decompose heme in acidic conditions. In contrast, BH formation was enhanced by amino acids with high hydrophobicity values (leucine, isoleucine, valine, methionine, and phenylalanine), with the exception of tryptophan at high temperature but was not affected in Tween-induced BH formation under normal physiological conditions. The present results can lead to further research on the development of new antimalarials by conjugating these amino acids, especially basic amino acids, with other substances, or by forming complex or small peptides that could have special effects on BH formation.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"Biological & Pharmaceutical Bulletin, 31(8), pp.1483-1488; 2008","subitem_description_type":"Other"}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The Pharmaceutical Society of Japan"}]},"item_2_relation_11":{"attribute_name":"PubMed番号","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"18670076","subitem_relation_type_select":"PMID"}}]},"item_2_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1248/bpb.31.1483","subitem_relation_type_select":"DOI"}}]},"item_2_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"(c) 2008 The Pharmaceutical Society of Japan"}]},"item_2_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA10885497","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09186158","subitem_source_identifier_type":"ISSN"}]},"item_2_source_id_8":{"attribute_name":"EISSN","attribute_value_mlt":[{"subitem_source_identifier":"1347-5215","subitem_source_identifier_type":"ISSN"}]},"item_2_version_type_16":{"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":"Dinh, Thanh Uyen"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Huy, Nguyen Tien"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Dai, Thi Xuan Trang"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nguyen, Thanh Thuy Nhien"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Oida, Tatsuo"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hirayama, Kenji"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Harada, Shigeharu"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kamei, Kaeko"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-23"}],"displaytype":"detail","filename":"BPB31_1483.pdf","filesize":[{"value":"255.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"BPB31_1483.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/18211/files/BPB31_1483.pdf"},"version_id":"9a7b2e52-614e-4fd1-860a-5f6cf2d64f22"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"amino acid","subitem_subject_scheme":"Other"},{"subitem_subject":"beta-hematin","subitem_subject_scheme":"Other"},{"subitem_subject":"hemozoin","subitem_subject_scheme":"Other"},{"subitem_subject":"heme","subitem_subject_scheme":"Other"},{"subitem_subject":"malaria","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":"Effects of Amino Acids on Malarial Heme Crystallization","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Effects of Amino Acids on Malarial Heme Crystallization"}]},"item_type_id":"2","owner":"2","path":["36"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-08-28"},"publish_date":"2008-08-28","publish_status":"0","recid":"18211","relation_version_is_last":true,"title":["Effects of Amino Acids on Malarial Heme Crystallization"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-16T04:05:06.637929+00:00"}
