Ponasterone A

Semi-synthetic. Soluble in acetic acid, ethanol, methanol or DMSO. Insoluble in water. A member of the ecdysteroid family. Ecdysone receptor (EcR) agonist. Analog of ecdysone with similar properties to muristerone A. Functional, reliable and economical substitute for muristerone A as an inducer for the ecdysone-inducible mammalian expression system. Induces expression of ?-galactosidase to levels similar to those obtained with muristerone A induction. Potent compound for ecdysteroid activity. Insect steroid hormone involved in regulating metamorphosis.
