Crustecdysone (Hydroxyecdysone) is a steroid hormone that regulates the processes of molting or ecdysis in insects.

Ecdysone is a major steroid hormone in insects and herbs. Ecdysone triggers mineralocorticoid receptor activation and induces cellular apoptosis. Ecdysone signaling through Ecdysone receptor isoform B1 is required cell autonomously for the muscle death.

2-O-Acetyl-20-hydroxyecdysone is an ecdysone present in insects and terrestrial plants. 2-O-Acetyl-20-hydroxyecdysone inhibits amyloid-β42-induced cytotoxicity and is able to reduce the formation of Aβ oligomers by promoting fibrillogenesis, which converts Aβ oligomers into less toxic fibers.

β-Gentiobiose is a natural oligosaccharide that promotes fruit ripening.

3-O-Acetyl-20-Hydroxyecdysone, a steroid extracted from the roots of Cyanotis arachnoidea C.B.Clark, is characterized by its unique structural modifications.

Makisterone A is an ecdysteroid that drives molting in insects. It binds the heterodimeric ecdysone receptor with nanomolar affinity.

Ponasterone A is an ecdysteroid with high affinity for the ecdysteroid receptor. It enables rapid switching on and off of reporter genes and is a potent regulator of gene expression in cells and transgenic animals.

Muristerone A is a phytoecdysteroid analog of ecdysone and a potent ecdysteroid receptor agonist with a K d of 1 nM [1].
