DIC is a fatal cardiomyopathy with a worse prognosis compared to other cardiomyopathies and limits the use of DOX in malignancies due to its cardiotoxicity. DIC has been proven to be associated with reactive oxygen species (ROS)-induced side effect damage in cardiac myocytes. Currently, scavenging of reactive oxygen species is a practical strategy to reduce chemotherapy-associated DIC. Although quercetin has already been reported to have superior antioxidant activity, its clinical application is severely limited due to its rapid degradation and poor tissue absorption. Herein, we reported the preparation of a novel enzyme mimic via coordinated albumin, Zinc Ion (Zn2+) and quercetin. The enzyme mimics were capable of simultaneously increasing the biocompatibility and efficiently overcame the drawbacks of free quercetin, and were achieved by long circulation in vivo. Most importantly, these quercetin-based enzyme mimics had no effect on the antioxidant activity of quercetin. These beneficial therapeutic properties, together with high drug-carrying capacity and redox stimuli, will significantly improve quercetin\u2019s alleviation of chemotherapeutic cardiotoxicity without causing significant side effects. Therefore, nanoparticles of albumin-based Zn (II)-Quercetin have a promising clinical application as an effective agent for mitigating the cardiotoxicity of chemotherapy.<\/jats:p>","DOI":"10.3390\/ph15121524","type":"journal-article","created":{"date-parts":[[2022,12,9]],"date-time":"2022-12-09T01:51:26Z","timestamp":1670550686000},"page":"1524","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Albumin-Based Zn (II)-Quercetin Enzyme Mimic Scavenging ROS for Protection against Cardiotoxicity Induced by Doxorubicin"],"prefix":"10.3390","volume":"15","author":[{"given":"Zehua","family":"Shao","sequence":"first","affiliation":[{"name":"Heart Center of Zhengzhou University People\u2019s Hospital, Fuwai Central China Cardiovascular Hospital of Zhengzhou University, Henan Provincial People\u2019s Hospital, Zhengzhou 450003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ran","family":"Li","sequence":"additional","affiliation":[{"name":"Heart Center of Zhengzhou University People\u2019s Hospital, Fuwai Central China Cardiovascular Hospital of Zhengzhou University, Henan Provincial People\u2019s Hospital, Zhengzhou 450003, China"},{"name":"National Health Commission Key Laboratory of Cardiovascular Regenerative Medicine, Fuwai Central China Cardiovascular Hospital & Central China Branch of National Center for Cardiovascular Diseases, Zhengzhou 451464, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dongxing","family":"Shao","sequence":"additional","affiliation":[{"name":"National Health Commission Key Laboratory of Cardiovascular Regenerative Medicine, Fuwai Central China Cardiovascular Hospital & Central China Branch of National Center for Cardiovascular Diseases, Zhengzhou 451464, China"},{"name":"Beijing Key Laboratory of Protein Posttranslational Modifications and Cell Function, Department of Biochemistry and Molecular Biology, School of Basic Medical Sciences, Peking University Health Science Center, 38 Xueyuan Road, Beijing 100191, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5401-7295","authenticated-orcid":false,"given":"Hao","family":"Tang","sequence":"additional","affiliation":[{"name":"Heart Center of Zhengzhou University People\u2019s Hospital, Fuwai Central China Cardiovascular Hospital of Zhengzhou University, Henan Provincial People\u2019s Hospital, Zhengzhou 450003, China"},{"name":"National Health Commission Key Laboratory of Cardiovascular Regenerative Medicine, Fuwai Central China Cardiovascular Hospital & Central China Branch of National Center for Cardiovascular Diseases, Zhengzhou 451464, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu","family":"Han","sequence":"additional","affiliation":[{"name":"Heart Center of Zhengzhou University People\u2019s Hospital, Fuwai Central China Cardiovascular Hospital of Zhengzhou University, Henan Provincial People\u2019s Hospital, Zhengzhou 450003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"558","DOI":"10.1097\/FJC.0000000000001206","article-title":"Saikosaponin D Alleviates DOX-induced Cardiac Injury In Vivo and In Vitro","volume":"79","author":"Zhang","year":"2022","journal-title":"J.
