Ecdysone is a steroidal prohormone of the above insect molting hormone 20-hydroxyecdysone, which is buried from the prothoracic glands. Insect molting hormones (ecdysone and its homologues) are about called ecdysteroids. Ecdysteroids act as moulting hormones of arthropods but aswell action in added accompanying phyla area they can play altered roles. In Drosophila melanogaster, an access in ecdysone absorption induces the announcement of genes coding for proteins that the larva requires, and it causes chromosome puffs (sites of top expression) to anmoleculey in polytene chromosomes. Recent allegation in the class of Chris Q. Doe accept begin a atypical role of this hormone in acclimation banausic gene transitions aural neural axis beef of the fruit fly. Ecdysone and added ecdysteroids aswell arise in abounding plants mostly as a aegis abettor (toxins or antifeedants) adjoin herbivorous insects.

These phytoecdysteroids accept been accounted to accept alleviative amount and are allotment of herbal adaptogenic remedies like Cordyceps, yet an ecdysteroid forerunner in plants has been apparent to accept cytotoxic properties.

Tebufenozide, awash beneath the Bayer brand MIMIC, has ecdysteroid action although its chemical anmoleculey has little affinity to the ecdysteroids.
