The muscarinic antagonists scopolamine and atropine are competitive antagonists at 5-HT3 receptors. [PDF]

open access: yesNeuropharmacology, 2016
Scopolamine is a high affinity muscarinic antagonist that is used for the prevention of post-operative nausea and vomiting. 5-HT3 receptor antagonists are used for the same purpose and are structurally related to scopolamine. To examine whether 5-HT3 receptors are affected by scopolamine we examined the effects of this drug on the electrophysiological ...

Investigating the Unbinding of Muscarinic Antagonists from the Muscarinic 3 Receptor. [PDF]

open access: yesJ Chem Theory Comput, 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

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 ...
