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

ecdysone receptor^[2]

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

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