Abstract:
In order to develop agonist ligands that are specific for the estrogen-related receptors ERRbeta/gamma, a hydrazone with a 4-hydroxy group at one phenyl ring and a 4-diethylamino moiety at the other phenyl ring was synthesized. We demonstrate that compound 3 (DY131; N'-{(1E)-[4-(diethylamino)phenyl]methylene}-4-hydroxybenzohydrazide) effectively and selectively activates ERRbeta/gamma. DY131 had no effect on the structurally related receptors ERRalpha or the estrogen receptors alpha and beta (ERalpha/beta). This work defines a convenient synthesis for a novel and selective pharmacologic tool that can be used to elucidate the biological activities of ERRbeta/gamma.

Drug-Receptor Interaction: Agonist
Agonists can bind to receptors in different ways. Some agonists bind directly to the receptor's active site, mimicking the endogenous ligand's action.
Transducer Mechanism: Nuclear Receptors
About 48 different soluble family members of nuclear receptors are identified that can be divided into two main classes:
The Two-State Receptor Model
The binding affinity of a drug determines its interaction with one...
Drug-Receptor Interactions
Several parameters, such as the drug's affinity for its receptor and its efficacy, which is its ability to activate the receptor, determine the drug's effect on the tissue.
Internal Receptors
Transducer Mechanism: Enzyme-Linked Receptors
Major types that are helpful drug targets include:
