Repurposing NIC presents a current trend, offering significant time and cost savings compared to developing entirely new therapeutic chemical entities. However, its drawback lies in poor solubility, resulting in notably low oral bioavailability. This review consolidates efforts to overcome this limitation by summarizing twelve categories of formulations, spanning derivatives, amorphous solid dispersions, co-crystals, nanocrystals, micelles, nanohybrids, lipid nanoparticles and emulsions, cyclodextrins, polymeric nanoparticles, dry powders for inhalation, 3D printlets, and nanofibers. These formulations cover oral, injectable, inhalable and potentially (trans)dermal routes of administration. Additionally, we present a comprehensive overview of NIC characteristics, including physico-chemical properties, metabolism, safety, and pharmacokinetics. Moreover, we identify gaps in formulation and administration pathways that warrant further investigation to address NIC poor bioavailability.<br/><br/><strong>Keywords:</strong> niclosamide, drug repurposing, solubility, formulations, administration pathways, pharmaco-kinetics<br/>","PeriodicalId":11290,"journal":{"name":"Drug Design, Development and Therapy","volume":"16 1","pages":""},"PeriodicalIF":4.8,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142269605","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Exploring the mechanism and prevention strategy of cancer therapy-related cardiovascular toxicity (CTR-CVT) remains one of the research hotspots in the field of Cardio-Oncology in recent years. Cardiotoxicity of anticancer drugs involves heart failure, myocarditis, hypertension, arrhythmias and vascular toxicity, mechanistically related to vascular endothelial dysfunction, ferroptosis, mitochondrial dysfunction and oxidative stress. To address the cardiotoxicity induced by different anticancer drugs, various therapeutic measures have been put in place, such as reducing the accumulation of anticancer drugs, shifting to drugs with less cardiotoxicity, using cardioprotective drugs, and early detection. Due to the very limited treatments available to ameliorate anticancer drugs-induced cardiotoxicity, a few innovations are being shifted from animal studies to human studies. Examples include mitochondrial transplantation. Mitochondrial transplantation has been proven to be effective in in vivo and in vitro experiments. Several recent studies have demonstrated that intercellular mitochondrial transfer can ameliorate doxorubicin(DOX)-induced cardiotoxicity, laying the foundation for innovative therapies in anticancer drugs-induced cardiotoxicity. In this review, we will discuss the current status of anticancer drugs-induced cardiotoxicity in terms of the pathogenesis and treatment, with a focus on mitochondrial transplantation, and we hope that this review will bring some inspiration to you. <br/><br/><strong>Keywords:</strong> cancer therapy-related cardiovascular toxicity, CTR-CVT, mitochondrial dysfunction, oxidative stress, ferroptosis, mitochondrial transplantation<br/>","PeriodicalId":11290,"journal":{"name":"Drug Design, Development and Therapy","volume":"3 1","pages":""},"PeriodicalIF":4.8,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142178577","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
