20-Hydroxyecdysone (ecdysterone or 20E) is a naturally occurring ecdysteroid hormone which controls the scdysis (moulting) and metamorphosis of arthropods. It is therefore one of the most common moulting hormones in insects, crabs, etc. It is also a phytoecdysteroid produced by various plants, including Cyanotis, where its purpose is presumably to disrupt the development and reproduction of insect pests. In arthropods, 20E acts through the ecdysterone receptor. Although mammals lack this receptor, 20E does appear to affect mammalian(including human) physiology, but there is disagreement over the details of its effects. 20E is an ingredient of some preparations that aim to enhance physical performance.
