Induction of choriogenesis by 20-hydroxyecdysone in the german cockroach

Tissue and Cell, 1993
Experiments in vitro have shown that 20-hydroxyecdysone (at a concentration of 0.2 and 2 microM and after 12 and 24 hr of incubation) is able to induce the precocious deposition of chorion materials by the follicular epithelium of young oocytes of the cockroach Blattella germanica.

Stereoselective synthesis and moulting activity of 2,3-diepi-20-hydroxyecdysone and 2,3-diepi-5α-20-hydroxyecdysone

Tetrahedron, 2004
The ecdysteroid analogues 2,3-diepi-20-hydroxyecdysone and 2,3-diepi-5α-20-hydroxyecdysone have been synthesized from the readily available ecdysteroid, 20-hydroxyecdysone, and moulting activity has been determined using the Musca bioassay. As expected, the 2,3-diepi-analogue was less active than the parent ecdysteroid, 20-hydroxyecdysone. However, the

Juvenile hormone membrane signaling phosphorylates USP and thus potentiates 20-hydroxyecdysone action in Drosophila.

Science Bulletin, 2021
Juvenile hormone (JH) and 20-hydroxyecdysone (20E) coordinately regulate development and metamorphosis in insects. Two JH intracellular receptors, methoprene-tolerant (Met) and germ-cell expressed (Gce), have been identified in the fruit fly Drosophila ...

Activation of the ROS/CncC and 20-Hydroxyecdysone Signaling Pathways Is Associated with Xanthotoxin-Induced Tolerance to λ-Cyhalothrin in Spodoptera litura.

Journal of Agricultural and Food Chemistry, 2021
Adaptation to phytochemicals in herbivorous insects can influence tolerance to insecticides. However, it is unclear how insects use phytochemicals as cues to activate their metabolic detoxification systems.

Proapoptotic and proautophagic activity of 20-hydroxyecdysone in breast cancer cells in vitro.

Chemico-Biological Interactions, 2021
The present study was designed to identify the biological activity of three ecdysones, i.e., 20-hydroxyecdysone (20-HE), ajugasterone C, and polypodine B isolated from Serratula coronata.
