Biological Activity

[Description]:

Ponasterone A (25-Deoxyecdysterone), an ecdysteroid, has strong affinity for the ecdysone receptor. Ponasterone A is a potent regulator of gene expression in cells and transgenic animals, enabling reporter genes to be turned on and off rapidly[1][2].

[Target]

ecdysone receptor[2]

[In Vitro]

Ponasterone A (1 nM-100 μM) shows significant gene induction activity in CV-1 cells[2].

[In Vivo]

Ponasterone A (3-10 mg; i.p.) produces robust inductions of gene expression in transactivator and reporter mice[2].
