Oxo-analogues of 20-hydroxyecdysone in the synthesis of novel fluorinated ecdysteroid derivatives [PDF]

, 2018
Novel side chain ω-fluorinated ecdysteroid analogues were obtained starting from ω-functionalized ecdysteroids. Thus, the reaction of diacetonides of 25RS-hydroxy- and 24-hydroxy 27-nor- and 25,26,27-tris-nor-20-hydroxyecdysone derivatives with ...

Phytoecdysteroids in the Genus (Polypodiaceae) of French Polynesia

Natural Product Communications, 2007
A chemical survey of the six species of Microsorum in French Polynesia has been performed to determine and quantify the phytoecdysteroids. The content and composition of these compounds in the fronds of each of the six species were established.

miR-34-5p mediates 20E-induced autophagy in the fat body of Bombyx mori by targeting Atg1

BMC Genomics
Background 20-Hydroxyecdysone (20E) is an important hormone that regulates insect development and metamorphosis. The fat body of insects plays a crucial role in nutrient storage and energy metabolism and is considered the exchange center for regulating ...

SRP/dGATAb modulates the ecdysone response bidirectionally via locus-specific regulatory landscape

Epigenetics & Chromatin
Background Steroid hormones drive the transcription of developmental genes by activating distinct sets of enhancers across tissues and developmental contexts, but the mechanisms that target specific enhancers remain incompletely understood, even in model

Disrupting shadow in the prothoracic gland induced larval development arrest in the fall armyworm Spodoptera frugiperda

Frontiers in Physiology
IntroductionThe juvenile hormone (JH) and 20-hydroxyecdysone (20E) are the central regulating hormones of insect development. The timing of their secretion usually leads to developmental transitions.MethodsThe developmental transitions were evaluated via

L'arrêt du développement chez les lépidoptères : la 20-hydroxyecdysone est-elle toujours impliquée?

, 2018
Le développement des insectes est régulé par diverses hormones dont les deux principales sont la 20-hydroxyecdysone et l'hormone juvénile. Certains facteurs endogènes ou exogènes comme la diapause et le parasitisme, respectivement, peuvent perturber le ...
