Higenamine, a natural product with multiple targets in heart diseases, is originally derived from Aconitum, which has been traditionally used in China for the treatment of heart disease, including heart failure, arrhythmia, bradycardia, cardiac ischemia/reperfusion injury, cardiac fibrosis, etc. This study is aimed to clarify the role of higenamine in heart diseases. Higenamine has effects on improving energy metabolism of cardiomyocytes, anti-cardiac fibroblast activation, anti-oxidative stress and anti-apoptosis. Accumulating evidence from various studies has shown that higenamine exerts a wide range of cardiovascular pharmacological effects in vivo and in vitro, including alleviating heart failure, reducing cardiac ischemia/reperfusion injury, attenuating pathological cardiac fibrosis and dysfunction. In addition, several clinical studies have reported that higenamine could continuously increase the heart rate levels of healthy volunteers as well as patients with heart disease, but there are variable effects on systolic blood pressure and diastolic blood pressure. Moreover, the heart protection and therapeutic effects of higenamine on heart disease are related to regulating LKB1/AMPKα/Sirt1, mediating the β2-AR/PI3K/AKT cascade, induction of heme oxygenase-1, suppressing TGF-β1/Smad signaling, and targeting ASK1/MAPK (ERK, P38)/NF-kB signaling pathway. However, the interventional effects of higenamine on heart disease and its underlying mechanisms based on experimental studies have not yet been systematically reviewed. This paper reviewed the potential pharmacological mechanisms of higenamine on the prevention, treatment, and diagnosis of heart disease and clarified its clinical applications. The literature shows that higenamine may have a potent effect on complex heart diseases, and proves the profound medicinal value of higenamine in heart disease.

Heart failure is a devastating disease characterized by chamber remodeling, interstitial fibrosis and reduced ventricular compliance. Cardiac fibroblasts are responsible for extracellular matrix homeostasis, however upon injury or pathologic stimulation, these cells transform to a myofibroblast phenotype and play a fundamental role in myocardial fibrosis and remodeling. Chronic sympathetic overstimulation induces excess signaling through G protein βγ subunits and ultimately the pathologic activation of G protein-coupled receptor kinase 2 (GRK2). We hypothesized that Gβγ-GRK2 inhibition plays an important role in the cardiac fibroblast to attenuate pathologic myofibroblast activation and cardiac remodeling. To investigate this hypothesis, mice were subjected to ischemia/reperfusion (I/R) injury and treated with the small molecule Gβγ-GRK2 inhibitor gallein. While animals receiving vehicle demonstrated a reduction in overall cardiac function as measured by echocardiography, mice treated with gallein exhibited nearly complete preservation of cardiac function and reduced fibrotic scar formation. We next sought to establish the cell specificity of this compound by treating inducible cardiomyocyte- and activated fibroblast-specific GRK2 knockout mice post-I/R. Although we observed modest restoration in cardiac function in cardiomyocyte-specific GRK2 null mice, treatment of these mice with gallein resulted in further protection against myocardial dysfunction following injury, suggesting a functional role in other cardiac cell types, including fibroblasts. Activated fibroblast-specific GRK2 knockout mice were also subjected to ischemia/reperfusion injury; these animals displayed preserved myocardial function and reduced collagen deposition compared to littermate controls following injury. Furthermore, systemic Gβγ-GRK2 inhibition by gallein did not appear to confer further protection over activated fibroblast-specific GRK2 ablation alone. In summary, these findings suggest a potential therapeutic role for Gβγ-GRK2 inhibition in limiting pathologic myofibroblast activation, interstitial fibrosis and heart failure progression.
