The role of kinetic context in apparent biased agonism at GPCRs [PDF]
Biased agonism describes the ability of ligands to stabilize different conformations of a GPCR linked to distinct functional outcomes and offers the prospect of designing pathway-specific drugs that avoid on-target side effects. This mechanism is usually

Hyperactivity in Mice Induced by Opioid Agonists with Partial Intrinsic Efficacy and Biased Agonism Administered Alone and in Combination with Morphine. [PDF]
Opioid analgesics such as morphine and fentanyl induce mu-opioid receptor (MOR)-mediated hyperactivity in mice. Herein, we show that morphine, fentanyl, SR-17018, and oliceridine have submaximal intrinsic efficacy in the mouse striatum using 35S-GTPγS ...

Physiological implications of biased signaling at histamine H2 receptors [PDF]
Histamine mediates numerous functions acting through its four receptor subtypes all belonging to the large family of seven transmembrane G-protein coupled receptors. In particular, histamine H2 receptor (H2R) is mainly involved in gastric acid production,

Ligand recognition and biased agonism of the D1 dopamine receptor. [PDF]
D1 dopamine receptor is an important drug target for treatment of hypertension and Parkinson’s disease. Here, authors report three cryo-EM structures of the D1R-Gs complex bound to three distinct D1R-selective drugs.

Recent updates on GPCR biased agonism [PDF]
G protein-coupled receptors (GPCRs) are the most important targets for drug discovery and not surprisingly ∼40% of all drugs currently in the market act on these receptors. Currently, one of the most active areas in GPCRs signaling is biased agonism, a phenomenon that occurs when a given ligand is able to preferentially activate one (or some) of the ...

Gating Mechanism for Biased Agonism at Angiotensin II Type 1 Receptors. [PDF]
For the interaction of angiotensin II (AngII) with AngII type 1 receptors (AT1R), two potential proton hopping pathways have been identified, each associated with distinct physiological outcomes.

Allosteric coupling and biased agonism in G protein‐coupled receptors [PDF]
G protein‐coupled receptors (GPCRs) are essential cell membrane signaling molecules and represent the most important class of drug targets. Some signaling pathways downstream of a GPCR may be responsible for drug adverse effects, while others mediate therapeutic efficacy.

Structural basis of protease-activated receptor 2 activation and biased agonism. [PDF]
Protease-activated receptor 2 (PAR2) is a transmembrane receptor that is irreversibly activated by proteolytic cleavage of its N-terminus via extracellular proteases, resulting in the release of the tethered ligand (TL), which binds to and activates the ...

G Protein-coupled Receptor Biased Agonism. [PDF]
G protein-coupled receptors are the largest family of targets for current therapeutics. The classic model of their activation was binary, where agonist binding induced an active conformation and subsequent downstream signaling. Subsequently, the revised concept of biased agonism emerged, where different ligands at the same G protein-coupled receptor ...
