Muscarinic Receptor Agonists and Antagonists [PDF]

open access: goldMolecules, 2001
A comprehensive review of pharmacological and medical aspects of the muscarinic class of acetylcholine agonists and antagonists is presented. The therapeutic benefits of achieving receptor subtype selectivity are outlined and applications in the treatment of Alzheimer’s disease are discussed.

Isomerization of the muscarinic receptor . antagonist complex.

open access: hybridJournal of Biological Chemistry, 1979
The mechanism of binding of two antagonists, 3-quinuclidinyl benzilate and N-methyl-4-piperidinyl benzilate, to the muscarinic receptor was studied. The pseudo-first order rate constant of association showed a hyperbolic dependence on the concentration of the antagonist(s) indicating that the interaction involves two equilibria.

Multitargeting nature of muscarinic orthosteric agonists and antagonists

open access: yesFrontiers in Physiology, 2022
Muscarinic receptors (mAChRs) are typical members of the G protein-coupled receptor (GPCR) family and exist in five subtypes from M1 to M5. Muscarinic receptor subtypes do not sufficiently differ in affinity to orthosteric antagonists or agonists ...

Molecular probes for muscarinic receptors: Functionalized congeners of selective muscarinic antagonists [PDF]

open access: greenLife Sciences, 1995
The muscarinic agonist oxotremorine and the tricyclic muscarinic antagonists pirenzepine and telenzepine have been derivatized using a functionalized congener approach for the purpose of synthesizing high affinity ligand probes that are suitable for conjugation with prosthetic groups, for receptor cross-linking, fluorescent and radioactive detection ...

Migrastatin Acts as a Muscarinic Acetylcholine Receptor Antagonist [PDF]

open access: bronzeThe Journal of Antibiotics, 2006
Migrastatin and its analogs have various biological activities such as inhibition of cell migration and anchorage-independent growth of cancer cells. Although its biosynthesis and chemical synthesis have been under investigation, little is known about the biological target of migrastatin.

Investigating the Unbinding of Muscarinic Antagonists from the Muscarinic 3 Receptor

open access: yesJournal of Chemical Theory and Computation, 2023
Patient symptom relief is often heavily influenced by the residence time of the inhibitor-target complex. For the human muscarinic receptor 3 (hMR3), tiotropium is a long-acting bronchodilator used in conditions such as asthma or chronic obstructive pulmonary disease (COPD). The mechanistic insights into this inhibitor remain unclear; specifically, the

Additive interaction of intrathecal ginsenosides and neostigmine in the rat formalin test [PDF]

open access: yesKorean Journal of Anesthesiology, 2013
BackgroundThe authors evaluated the effect of intrathecal mixture of ginsenosides with neostigmine on formalin-induced nociception and made further clear the role of the spinal muscarinic (M) receptors on the activity of ginsenosides.MethodsA catheter ...

TLR2 and TLR4 Modulate Mouse Ileal Motility by the Interaction with Muscarinic and Nicotinic Receptors

open access: yesCells, 2022
Irritable bowel syndrome (IBS) is a chronic functional bowel disorder characterized by intestinal dysmotility. Changes in intestinal microbiota (dysbiosis) can lead to alterations in neuro-muscular functions in the gut. Toll-like receptors (TLRs) 2 and 4

The Spinal Muscarinic M1 Receptors and GABAA Receptors Contribute to the McN-A-343–Induced Antinociceptive Effects During Thermal Stimulation of Mice

open access: yesJournal of Pharmacological Sciences, 2008
The present study was undertaken to clarify how spinal muscarinic receptors are involved in the antinociceptive effects in thermal stimulation. Intrathecal (i.t.) injection of the muscarinic agonist McN-A-343 inhibited the tail-flick response to noxious ...
