Abstract:
This article summarizes recent research on the development of estrogen receptor alpha (ER alpha) and estrogen receptor beta (ER beta) subtype-selective ligands based on our understanding of structure-activity relationships in these two estrogen receptors and differences in their ligand binding domains and activation function domains. The use of these ligands should enable greater understanding of the unique biologies mediated by ER alpha versus ER beta and may, as well, provide selective estrogen receptor modulators having unique biological and pharmacological profiles optimal for prevention and treatment of breast cancer, for menopausal hormone replacement, for prevention of osteoporosis, and for potential cardiovascular benefit.

G Protein-coupled Receptors
GPCRs are also called heptahelical, 7TM, or serpentine receptors, and consist of seven (H1-H7) transmembrane alpha-helices that span the bilayer to form a cylindrical core. The transmembrane helices are connected by three extracellular loops and three...
Transducer Mechanism: Enzyme-Linked Receptors
Major types that are helpful drug targets include:
Transducer Mechanism: Nuclear Receptors
About 48 different soluble family members of nuclear receptors are identified that can be divided into two main classes:
Dose-Response Relationship: Selectivity and Specificity
Adrenergic Agonists: Chemistry and Structure-Activity Relationship
Aromatic ring substitutions: Substituting the aromatic ring with –OH groups at positions 3 and 4 yields catecholamines (e.g., epinephrine), which have a high affinity for adrenoceptors. Hydrogen bonding between –OH groups and receptors enhances adrenergic activity.
Separation of the aromatic...
