Summary
Selective estrogen receptor beta (ERβ) ligands are crucial for targeting diseases like cancer and osteoporosis. This review summarizes key ERβ ligands and analyzes their structure-activity relationships for therapeutic development.
Area of Science:
- Endocrinology
- Molecular Biology
- Pharmacology
Background:
- Estrogen receptors (ERs) are nuclear receptors implicated in diseases including cancer, inflammation, and osteoporosis.
- ERs exist as ERα and ERβ, with distinct functions and distributions.
- Selective ERβ targeting offers therapeutic advantages by modulating physiological functions while minimizing ERα-related side effects.
Purpose of the Study:
- To review various selective ERβ ligands.
- To analyze the structure-activity relationships of these ligands.
Main Methods:

Transducer Mechanism: Nuclear Receptors
5.5K
Nuclear receptors, or NRs, are unique transcription factors that regulate gene transcription and affect the cellular pathways involved in reproduction, development, or metabolism. Their ability to be stimulated by small lipophilic ligands and control vital cellular processes makes them ideal drug targets. Nearly 10-15% of currently prescribed drugs target these receptors.
About 48 different soluble family members of nuclear receptors are identified that can be divided into two main classes:

Adrenergic Antagonists: Chemistry and Classification of β-Receptor Blockers
1.7K
β-adrenergic antagonists, or β-blockers, modulate the sympathetic nervous system by targeting β-adrenoceptors and inhibiting catecholamine-mediated sympathetic responses. β-blockers differ in their adrenoceptor subtype affinity, lipophilicity, and α-blocking capabilities. The history of β-blocker development began with the prototype, dichloroisoprenaline, which exhibited partial agonist activity. As a result, propranolol was developed as a pure antagonist but...

Dose-Response Relationship: Selectivity and Specificity
10.7K
Drugs exert their therapeutic effects by interacting with receptors, enzymes, or ion channels that are present throughout the human body. The strength and duration of the interaction between a drug and its target receptor are characterized by the selectivity and specificity of the drug. Selectivity refers to a drug's strong preference for its intended target over other targets. For instance, isoprenaline, a non-selective β-adrenergic agonist, interacts with both β1- and...

Internal Receptors
76.5K
Many cellular signals are hydrophilic and therefore cannot pass through the plasma membrane. However, small or hydrophobic signaling molecules can cross the hydrophobic core of the plasma membrane and bind to internal, or intracellular, receptors that reside within the cell. Many mammalian steroid hormones use this mechanism of cell signaling, as does nitric oxide (NO) gas.

Transducer Mechanism: Enzyme-Linked Receptors
4.9K
Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.

G Protein-coupled Receptors
19.6K
G Protein-Coupled Receptors or GPCRs are membrane-bound receptors that transiently associate with heterotrimeric G proteins and induce an appropriate response to sensory stimuli such as light, odors, hormones, cytokines, or neurotransmitters.
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...
