Zusammenfassung: | The current study evaluates the effect of chelidonic acid on doxorubicin-induced cardiac toxicity. Chelidonic acid (CA) is a natural pyran-skeleton heterocyclic compound found in rhizomes of the perennial plant, celandine (Chelidonium majus).
Wistar rats were given an intraperitoneal injection of doxorubicin (1.25 mg/kg, cumulative dose of 20 mg/kg) four times per week for a duration of four weeks to induce cardiotoxicity. CA treatment (10, 20, and 40 mg/kg orally for four weeks) was started together with doxorubicin.
CA treatment reduced myocardial damage and improved cardiac dysfunction in doxorubicin-treated rats. It improved blood pressure, restored ST wave height and normalized the QTc interval compared to the rats treated only with doxorubicin. Administration of CA for four weeks reduced left ventricular end-diastolic pressure. Moreover, CA treatment decreased the level of cardiac markers such as creatine kinase-myocardial band (CK-MB), lactate dehydrogenase (LDH), aspartate aminotransferase (AST), and cardiac troponin-T. Masson's trichrome, hematoxylin, and eosin staining of heart tissue revealed that CA attenuated the deleterious effects of doxorubicin and prevented further damage and fibrosis in rats.
The study findings confirm that CA treatment can protect the myocardium against doxorubicin-induced cardiotoxicity.
O presente estudo avalia o efeito do ácido quelidónico na toxicidade cardíaca induzida pela doxorrubicina. O ácido quelidónico é um composto heterocíclico natural do esqueleto pirano encontrado nos rizomas da planta perene, celidónia (Chelidonium majus).
Ratos Wistar receberam injeção intraperitoneal de doxorrubicina (1,25 mg/kg, dose cumulativa de 20 mg/kg) quatro vezes por semana durante quatro semanas para induzir cardiotoxicidade. O tratamento com ácido quelidónico (10, 20 e 40 mg/kg por via oral durante quatro semanas) foi iniciado juntamente com a doxorrubicina.
O tratamento com ácido quelidónico reduziu o dano miocárdico e melhorou a disfunção cardíaca em ratos tratados com doxorrubicina. O tratamento com ácido quelidónico melhorou a pressão arterial, bem como restaurou a altura ST e normalizou o intervalo QTc em comparação com os únicos ratos tratados com doxorrubicina. A administração de ácido quelidónico por quatro semanas reduziu a pressão diastólica final do ventrículo esquerdo. Além disso, o tratamento com ácido quelidónico diminuiu o nível de marcadores cardíacos como creatina quinase-banda miocárdica (CK-MB), lactato desi |
