Description

Ponasterone A is a 2beta-hydroxy steroid, a 3beta-hydroxy steroid, a 14alpha-hydroxy steroid, a 20-hydroxy steroid, a 22-hydroxy steroid, a 6-oxo steroid and a phytoecdysteroid. Ponasterone A is a natural product found in Zoanthus, Lomaridium contiguum, and other organisms with data available. D006730 - Hormones, Hormone Substitutes, and Hormone Antagonists > D006728 - Hormones 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].
