Cyasterone is a phytoecdysteroid derived from plants, primarily researched for its role as an insect growth regulator. It acts as a molting hormone analog, influencing ecdysis and developmental processes in insects, which makes it valuable in agricultural entomology for developing novel, eco-friendly pest control methods targeting pest species. Additionally, like other ecdysteroids, it has been investigated for anabolic effects in mammals, including stimulation of muscle protein synthesis, promotion of muscle repair and growth, and potential therapeutic applications in muscle-wasting conditions such as sarcopenia or muscular dystrophy. It also shows anti-inflammatory and antioxidant properties, with emerging studies on its use in health supplements, anti-aging products, and plant defense mechanisms involving hormone signaling pathways.
