The Allosteric Activation of α7 nAChR by α-Conotoxin MrIC Is Modified by Mutations at the Vestibular Site

open access: yesToxins, 2021
α-conotoxins are 13–19 amino acid toxin peptides that bind various nicotinic acetylcholine receptor (nAChR) subtypes. α-conotoxin Mr1.7c (MrIC) is a 17 amino acid peptide that targets α7 nAChR.

Allosteric Modulators of G Protein-Coupled Dopamine and Serotonin Receptors: A New Class of Atypical Antipsychotics

open access: yesPharmaceuticals, 2020
Schizophrenia was first described by Emil Krapelin in the 19th century as one of the major mental illnesses causing disability worldwide. Since the introduction of chlorpromazine in 1952, strategies aimed at modifying the activity of dopamine receptors ...

Discovery of positive allosteric modulators and silent allosteric modulators of the μ-opioid receptor [PDF]

open access: yesProceedings of the National Academy of Sciences, 2013
μ-Opioid receptors are among the most studied G protein-coupled receptors because of the therapeutic value of agonists, such as morphine, that are used to treat chronic pain. However, these drugs have significant side effects, such as respiratory suppression, constipation, allodynia, tolerance, and dependence, as well as abuse potential.

Development of pyrimidone D1 dopamine receptor positive allosteric modulators

open access: yesBioorganic & Medicinal Chemistry Letters, 2021
MLS1082 is a structurally novel pyrimidone-based D1-like dopamine receptor positive allosteric modulator. Potentiation of D1 dopamine receptor (D1R) signaling is a therapeutic strategy for treating neurocognitive disorders. Here, we investigate the relationship between D1R potentiation and two prominent structural features of MLS1082, namely the ...

Potentiation and allosteric agonist activation of α7 nicotinic acetylcholine receptors: binding sites and hypotheses

open access: yesPharmacological Research, 2023
Considerable progress has been made in recent years towards the identification and characterisation of novel subtype-selective modulators of nicotinic acetylcholine receptors (nAChRs).

Allosteric Modulation of Muscarinic Acetylcholine Receptors

open access: yesPharmaceuticals, 2010
An allosteric modulator is a ligand that binds to an allosteric site on the receptor and changes receptor conformation to produce increase (positive cooperativity) or decrease (negative cooperativity) in the binding or action of an orthosteric agonist (e.

Conformational diversity in class C GPCR positive allosteric modulation

open access: yesNature Communications, 2023
AbstractThe metabotropic glutamate receptors (mGlus) are class C G protein coupled receptors (GPCR) that form obligate dimers activated by the major excitatory neurotransmitter L-glutamate1,2. The architecture of mGlu receptor comprises an extracellular Venus-Fly Trap domain (VFT) connected to a transmembrane domain (7TM) through a Cysteine-Rich Domain

Positive allosteric modulators of the a-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor [PDF]

open access: yes, 2010
L-glutamate is the major excitatory neurotransmitter in the mammalian central nervous system (CNS) and plays a fundamental role in the control of motor function, cognition and mood.

Conformational transitions and allosteric modulation in a heteromeric glycine receptor

open access: yesNature Communications, 2023
Glycine receptors (GlyR) are a critical postsynaptic component of spinal neurons. Here, the auhtors present cryo-EM structures of a heteromeric GlyR in the presence of an antagonist, agonist and agonist with a positive allosteric modulator.

Development of allosteric modulators of GPCRs for treatment of CNS disorders

open access: yesNeurobiology of Disease, 2014
The discovery of allosteric modulators of G protein-coupled receptors (GPCRs) provides a promising new strategy with potential for developing novel treatments for a variety of central nervous system (CNS) disorders.
