Mechanistic insights into the versatile stoichiometry and biased signaling of the apelin receptor-arrestin complex

open access: yesNature Communications
The apelin receptor (APJR) plays a pivotal role in regulating cardiovascular and metabolic health1,2. Understanding the mechanisms of biased agonism at APJR is crucial for drug discovery, as stimulation of the β-arrestin pathway may lead to some adverse ...

β-Arrestin-biased Agonism at the β2-Adrenergic Receptor [PDF]

open access: yesJournal of Biological Chemistry, 2008
Classically, the beta 2-adrenergic receptor (beta 2AR) and other members of the seven-transmembrane receptor (7TMR) superfamily activate G protein-dependent signaling pathways in response to ligand stimulus. It has recently been discovered, however, that a number of 7TMRs, including beta 2AR, can signal via beta-arrestin-dependent pathways independent ...

Signal transduction mechanism of biased ligands at histamine H2 receptors [PDF]

open access: yes, 2014
7TMRs (seven-transmembrane receptors) exist as conformational collections in which different conformations would lead to differential downstream behaviours such as receptor phosphorylation, G-protein activation and receptor internalization.

Biased agonism: An emerging paradigm in GPCR drug discovery [PDF]

open access: yesBioorganic & Medicinal Chemistry Letters, 2016
G protein coupled receptors have historically been one of the most druggable classes of cellular proteins. The members of this large receptor gene family couple to primary effectors, G proteins, that have built in mechanisms for regeneration and amplification of signaling with each engagement of receptor and ligand, a kinetic event in itself. In recent

Functional divergence in the role of N-linked glycosylation in smoothened signaling [PDF]

open access: yes, 2015
The G protein-coupled receptor (GPCR) Smoothened (Smo) is the requisite signal transducer of the evolutionarily conserved Hedgehog (Hh) pathway. Although aspects of Smo signaling are conserved from Drosophila to vertebrates, significant differences have ...

Mitragynine/Corynantheidine Pseudoindoxyls As Opioid Analgesics with Mu Agonism and Delta Antagonism, Which Do Not Recruit beta-Arrestin-2. [PDF]

open access: yes, 2016
Natural products found in Mitragyna speciosa, commonly known as kratom, represent diverse scaffolds (indole, indolenine, and spiro pseudoindoxyl) with opioid activity, providing opportunities to better understand opioid pharmacology.

G protein-coupled receptor-biased signaling: potential drug discovery to facilitate treatment of metabolic diseases

open access: yesActa Materia Medica
G protein-coupled receptors (GPCRs) are important, potential drug targets for the treatment of metabolic disorders, such as obesity. GPCRs crosstalk with several transducers, including heterotrimeric G proteins, GPCR kinases (GRKs), and β-arrestins. GPCR-

Advances in Achieving Opioid Analgesia Without Side Effects

open access: yesFrontiers in Pharmacology, 2018
Opioids are the most effective drugs for the treatment of severe pain, but they also cause addiction and overdose deaths, which have led to a worldwide opioid crisis. Therefore, the development of safer opioids is urgently needed.

Evaluation of Biased and Balanced Salvinorin A Analogs in Preclinical Models of Pain

open access: yesFrontiers in Neuroscience, 2020
In the search for safer, non-addictive analgesics, kappa opioid receptor (KOPr) agonists are a potential target, as unlike mu-opioid analgesics, they do not have abuse potential.

A GLP-1 analogue optimized for cAMP-biased signaling improves weight loss in obese mice

open access: yesMolecular Metabolism
Objective: Glucagon-like peptide 1 (GLP-1) receptor (GLP-1R) agonism is foundational to modern obesity pharmacotherapies. These compounds were engineered for maximal G protein alpha(s) (Gsα) signaling potency and downstream cAMP production. However, this
