Heart injury in patients with terminal cancer can lead to significant deterioration of left ventricular morphology and function. This specific heart condition is known as cancer-induced cardiac cachexia (CICC) and is characterized by cardiac dysfunction and wasting. However, an effective pharmacological treatment for CICC remains elusive.SUMMARYThe development and progression of CICC are closely related to pathophysiological processes, such as protein degradation, oxidative responses, and inflammation. Traditional Chinese medicine (TCM) monomers offer unique advantages in reversing heart injury, which is the end-stage manifestation of CICC except the regular treatment. This review outlines significant findings related to the impact of eleven TCM monomers, namely Astragaloside IV, Ginsenosides Rb1, Notoginsenoside R1, Salidroside, Tanshinone II A, Astragalus polysaccharides, Salvianolate, Salvianolic acids A and B, and Ginkgolide A and B, on improving heart injury. These TCM monomers are potential therapeutic agents for CICC, each with specific mechanisms that could potentially reverse the pathological processes associated with CICC. Advanced drug delivery strategies, such as nano-delivery systems and exosome-delivery systems, are discussed as targeted administration options for the therapy of CICC.KEY MESSAGEThis review summarizes the pathological mechanisms of CICC and explores the pharmacological treatment of TCM monomers that promote anti-inflammation, antioxidation, and pro-survival. It also considers pharmaceutical strategies for administering TCM monomers, highlighting their potential as therapies for CICC.","PeriodicalId":20209,"journal":{"name":"Pharmacology","volume":"53 1","pages":"1-13"},"PeriodicalIF":3.1,"publicationDate":"2024-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142180028","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
