Crustecdysone (20-Hydroxyecdysone) is a naturally occurring ecdysteroid hormone isolated from Cyanotis arachnoides C.B.Clarke which controls the ecdysis (moulting) and metamorphosis of arthropods, it inhibits caspase activity and induces autophagy via the 20E nuclear receptor complex, EcR-USP. Crustecdysone exhibits regulatory or protective roles in the cardiovascular system. Crustecdysone is an active metabolite of Ecdysone (α-Ecdysone; HY-N0179).
