蜕皮酮或为蜕皮甾酮(英语:Ecdysone)是一种昆虫的类固醇激素原,是涉及昆虫蜕皮的主要激素20-羟基蜕皮酮的前体,由前胸腺英语prothoracic gland分泌。蜕皮酮与其衍生物等统称为蜕皮激素,作用于节肢动物相关门类起到蜕皮与其它作用。在黑腹果蝇Drosophila melanogaster)中,蜕皮酮浓度的增加会诱导编码幼虫蜕皮所需基因的蛋白表达,并导致染色体膨大和多线染色体(polytene chromosomes)形成。Chris Q. Doe的实验室最近发现了蜕皮酮在果蝇的神经干细胞中的新作用[1]

蜕皮酮与其它蜕皮激素也存在于许多植物中,作为毒素或拒食剂来保护植物对抗植食性昆虫[2]。这些植物蜕皮类固醇英语phytoecdysteroid被认为具有药用价值,常作为草药补品上市,但其中部分成分可能具有细胞毒性[3]
