Cardioprotective and Hepatoprotective Actions of Phytoecdysteroids: Molecular and Clinical Perspectives
摘要
Phytoecdysteroids (PEs) are a distinctive class of polyhydroxylated plant-derived steroids that exhibit pronounced cardioprotective and hepatoprotective activities, clearly differentiating them from synthetic anabolic steroids and conventional hepatoprotective agents. Experimental and clinical studies show that ecdysterone, turkesterone, cyasterone, and related analogs act through multiple interconnected mechanisms. These include inhibition of lipid peroxidation, stabilization of mitochondrial bioenergetics, and preservation of membrane integrity. In addition, they normalize carbohydrate and lipid metabolism and modulate intracellular signaling pathways. In cardiac models, phytoecdysteroids reduce myocardial necrosis, preserve glycogen and ATP stores, prevent arrhythmias by maintaining Na+/K+ homeostasis, and protect the ultrastructural integrity of sarcomeres and mitochondria. In models of liver injury, they significantly lower serum transaminase and bilirubin levels, attenuate centrilobular necrosis, reduce hepatic cholesterol and triglyceride accumulation, enhance bile secretion, and preserve mitochondrial respiration. Clinical use of phytoecdysteroid-based preparations, such as Ecdysten and Eksumid, has confirmed these beneficial effects in patients with ischemic heart disease, myocardial dystrophy, and toxic or viral hepatitis. Treatment was associated with improved biochemical parameters, functional recovery, and overall well-being. Notably, phytoecdysteroids exhibit an excellent safety profile, lacking androgenic, hepatotoxic, or endocrine-disrupting effects even during prolonged administration. Collectively, these findings indicate that phytoecdysteroids act as multifunctional adaptogenic agents. They show substantial translational potential in cardiovascular and hepatic medicine by safely protecting and restoring vital organs under metabolic, toxic, and ischemic stress.
