Ecdysone is a steroidal prohormone of the major insect molting hormone 20-hydroxyecdysone, which is secreted from the prothoracic glands. Insect molting hormones (ecdysone and its homologues) are generally called ecdysteroids. Ecdysteroids act as moulting hormones of arthropods but also occur in other related phyla where they can play different roles. In Drosophila melanogaster, an increase in ecdysone concentration induces the expression of genes coding for proteins that the larva requires, and it causes chromosome puffs (sites of high expression) to form in polytene chromosomes. Recent findings in the laboratory of Chris Q. Doe have found a novel role of this hormone in regulating temporal gene transitions within neural stem cells of the fruit fly.

A novel plant-derived ecdysone agonist from sida cordifolia and its preparation method and application
This invention discloses a novel plant-derived ecdysone antagonist derived from Dryopteris crassirhizoma, its preparation method, and its application, belonging to the field of biological control of agricultural pests and green pesticide technology. The novel plant-derived ecdysone antagonist disclosed in this invention has the molecular formula C0.05. 21 H 24 O8. This invention discloses a novel plant-derived ecdysone antagonist derived from Dryopteris crassirhizoma, targeting the insect's unique developmental system. It exhibits high safety for non-target organisms such as mammals and pollinating insects, and is readily degradable in the environment, perfectly meeting the dual requirements of agricultural product safety and ecological protection. This invention not only provides a novel pesticide but also establishes a complete technical system from target discovery and efficient screening to green application.
