Embodiment 1

[0029] Example 1 Application of leucanthin in the preparation of medicaments for preventing and treating heart failure and pathological cardiac remodeling.

[0030] (1) Experimental animals

[0031] 12-week-old healthy male C57BL / 6J mice were provided by the Animal Experiment Center of the Air Force Military Medical University of the Chinese People's Liberation Army.

[0032] (2) Experimental materials

[0033] Lactocin (abbreviated as LCP, purity >95%) was purchased from Merck Sigma Company, product number PHL84796; Metoprolol (Metoprolol, purity >95%) was purchased from MedChemExpress Company, product code HY-17503.

[0034] (3) Animal model construction

[0035] The 12-week-old male C57BL6J mice underwent permanent ligation of the left anterior descending coronary artery for 28 days to establish a model of heart failure and pathological cardiac remodeling. The mice were randomly divided into 5 groups with 20 mice in each group, which were divided into: (1) Sham operation...

Abstract

The invention relates to the technical field of biomedicine, in particular to the application of leucanthin in the preparation of medicines for preventing and treating heart failure and pathological cardiac remodeling. The medicine uses leucanthin as an active ingredient, and can be mixed with pharmaceutically acceptable, inert, non-toxic excipients or carrier auxiliary materials to prepare a clinical medicine that is convenient for oral or intravenous application. Specifically, the application of leucetin in the preparation of anti-heart failure drugs, the application of leucetin in the preparation of anti-cardiac insufficiency drugs, the application of leucetin in the preparation of anti-pathological cardiac remodeling drugs, The role of leucanthin in the preparation of anti-cardiomyocyte hypertrophy drugs, the application of leucetin in the preparation of anti-cardiac interstitial fibrosis drugs, and the application of leucetin in the preparation of anti-cardiomyocyte death drugs.

Description

technical field [0001] The invention relates to the technical field of biomedicine, in particular to the application of leucanthin in the preparation of medicines for preventing and treating heart failure and pathological cardiac remodeling. Background technique [0002] Heart failure is a clinical syndrome manifested by the progression to the end stage of various cardiovascular diseases such as coronary atherosclerotic heart disease, myocardial infarction, hypertension, myocarditis and cardiomyopathy. A variety of symptoms caused by the inability to meet the blood supply to organs throughout the body. The key pathogenic mechanism of heart failure is pathological cardiac remodeling, which is mainly manifested by cardiomyocyte hypertrophy, myocardial interstitial fibrosis and myocardial cell death. How to effectively alleviate pathological cardiac remodeling becomes the prevention and treatment of heart failure and cardiac insufficiency. bottleneck link. [0003] At present...
