Biochem/physiol Actions

AB-1 is a highly selective estrogen receptors ERα and ERβ modulator over G protein-coupled estrogen receptor GPER. AB-1 is an agonist of ER transcriptional activity, but it acts as an antagonist of rapid signaling through ERα.

Estrogen receptors alpha (ERalpha) and beta (ERbeta) have distinct functions and differential expression in certain tissues. These differences have stimulated the search for subtype-selective ligands. Therapeutically, such ligands offer the potential to target specific tissues or pathways regulated by one

Estrogen exerts extensive and diverse effects throughout the body of women. In addition to the classical nuclear estrogen receptors (ERα and ERβ), the G protein-coupled estrogen receptor GPER is an important mediator of estrogen action. Existing ER-targeted therapeutic agents act

An oxabicyclic template for estrogen receptor alpha and beta agonists has been identified which can be tuned to provide moderate levels of selectivity for either receptor sub-type. Structure-activity relationships within this phenol-substituted oxabicyclo[3.3.1]nonene series are described. Select compounds from the
