Glucagon-like Receptor Agonists

Glucagon-like Receptor Agonists

Incretins include glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), which stimulate insulin secretion post-meals. In type 2 diabetes, GIP's efficacy is reduced, making GLP-1 a viable drug target. GIP originates from preproGIP.
GLP-1, when administered in high doses intravenously, triggers insulin secretion, inhibits glucagon release, slows gastric emptying, reduces food intake, and restores normal insulin secretion. However, its rapid inactivation by the...

Target Cell Response to Hormones

Target Cell Response to Hormones

Hormones intricately bind to receptors on the surface or within target cells, initiating a cascade of cellular responses.
Notably, the cellular response can be regulated by altering the number of receptors expressed in the cell. For example, prolonged exposure to elevated hormone levels results in a gradual decline or down-regulation in the number of receptors for that specific hormone on the cell surface. Conversely, in response to low hormone levels, cells may use up-regulation, producing an...

Transducer Mechanism: Enzyme-Linked Receptors

Transducer Mechanism: Enzyme-Linked Receptors

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.
Major types that are helpful drug targets include:

Oral Hypoglycemic Agents: Glinides

Oral Hypoglycemic Agents: Glinides

Repaglinide (Prandin) and Nateglinide (Starlix), known as glinides, are oral insulin secretagogues that stimulate insulin release from pancreatic β cells by closing the ATP-sensitive potassium channels (KATP channel). Repaglinide controls insulin release from pancreatic β cells by managing potassium efflux. It shares two binding sites with sulfonylureas and also has a unique site, indicating overlapping mechanisms of action. With a rapid onset and a 4-7 hour duration, it effectively manages...

Transducer Mechanism: G Protein–Coupled Receptors

Transducer Mechanism: G Protein–Coupled Receptors

G Protein–Coupled Receptors (GPCRs) are membrane-bound receptors that transiently associate with heterotrimeric G proteins and induce an appropriate response to various stimuli. GPCRs regulate critical physiological pathways and are excellent drug targets for treating diseases such as diabetes, cancer, obesity, depression, or Alzheimer's. Nearly 35% of approved drugs implement their therapeutic effects by selectively interacting with specific GPCRs.
GPCRs are also called heptahelical, 7TM, or...

Intracellular Hormone Receptors

Intracellular Hormone Receptors

Lipid-soluble hormones diffuse across the plasma and nuclear membrane of target cells to bind to their specific intracellular receptors. These receptors act as transcription factors that regulate gene expression and protein synthesis in the target cell

Pharmacology

Background:

Growth hormone (GH) is crucial for somatic growth, metabolism, and body composition.
GH exerts its effects through the GH receptor (GHR), activating key signaling pathways like STATs, MAPK, and PI3-kinase/Akt.
GHR function is complex, influenced by ligand binding, receptor structure, and intracellular signaling.

Purpose of the Study:

To review modulators of GH receptor (GHR) signaling.
To explore novel GH agonists and antagonists based on GHR binding and activation mechanisms.
To discuss strategies for developing long-acting GHR agonists and understanding GHR regulation.

Main Methods:

Review of literature on GH receptor (GHR) binding, stoichiometry, and signal transduction.
Analysis of strategies for creating long-acting GHR agonists, including pegylation and fusion proteins.
Examination of hormonal regulation of GHR expression and signaling, such as the role of estrogens and SOCS proteins.

Main Results:

Novel GH agonists and antagonists have been developed based on GHR binding insights.
Pegylation of GH analogues, like pegvisomant, offers a successful strategy for treating acromegaly by blocking GHR activation.
Hormones such as insulin, thyroid, and sex hormones modulate GHR activity through various mechanisms, including receptor expression and signaling inhibition via SOCS proteins.

Conclusions:

Modulating GH receptor (GHR) activity through ligand modification and regulation of receptor expression/signaling presents significant therapeutic opportunities.
Understanding the intricate mechanisms of GHR regulation is key to developing effective treatments for GH-related disorders.
Future research should focus on refining GHR modulators and exploring their full therapeutic potential.
