Cardamonin intervenes in myocardial hypertrophy progression by regulating Usp18

Myocardial hypertrophy is a chronic cardiac condition that often occurs from long-term pressure or volumetric load on the heart. Propranolol hydrochloride has been employed in research on hypertension, pheochromocytoma, myocardial infarction, arrhythmias, angina pectoris, and hypertrophic cardiomyopathy. Current treatments for this condition have side effects, such as arrhythmias and myocardial cell death, thus necessitating safer and more effective alternatives. Recently, natural products have gained attention in drug development because of their low toxicity and high efficacy. Cardamonin, a compound derived from Chinese herbal materials, has shown potential in inhibiting oxidative stress and inflammation, which is beneficial for cardiovascular health. Nevertheless, the impact on myocardial hypertrophy and cardiac remodeling is still uncertain METHODS: Approach We employed a transverse aortic constriction (TAC)model to simulate the pathological conditions of myocardial hypertrophy. Mice were administered varying doses of CAR (10 and 40 mg kg
