Inhaled corticosteroids with combination inhaled long-acting beta2-agonists and long-acting muscarinic antagonists for chronic obstructive pulmonary disease.

Cochrane Database of Systematic Reviews, 2016
BACKGROUND Management of chronic obstructive pulmonary disease (COPD) commonly involves long-acting bronchodilators including beta-agonists (LABA) and muscarinic antagonists (LAMA).

Methylene Blue Is a Muscarinic Antagonist in Cardiac Myocytes [PDF]

Molecular Pharmacology, 1997
We studied the mechanism of action of methylene blue (Mblue), a putative guanylyl cyclase inhibitor, on the L-type calcium current (ICa) and the muscarinic activated K+ current (IK,ACh) in rat ventricular and atrial myocytes, respectively, and on the binding of [3H]quinuclidinyl benzylate in rat ventricular membranes.

Striatal cholinergic interneurons generate beta and gamma oscillations in the corticostriatal circuit and produce motor deficits [PDF]

, 2016
Cortico-basal ganglia-thalamic (CBT) neural circuits are critical modulators of cognitive and motor function. When compromised, these circuits contribute to neurological and psychiatric disorders, such as Parkinson's disease (PD).

The structural study of mutation-induced inactivation of human muscarinic receptor M4

IUCrJ, 2020
Human muscarinic receptor M4 belongs to the class A subfamily of the G-protein-coupled receptors (GPCRs). M4 has emerged as an attractive drug target for the treatment of Alzheimer's disease and schizophrenia.

Identification of atropine-and P2X1 receptor antagonist-reistant, neurogenic contractions of the urinary bladder [PDF]

, 2007
Acetylcholine and ATP are excitatory cotransmitters in parasympathetic nerves. We used P2X1 receptor antagonists to further characterize the purinergic component of neurotransmission in isolated detrusor muscle of guinea pig urinary bladder.

Single Inhaler LABA/LAMA for COPD

Frontiers in Pharmacology, 2019
Chronic obstructive pulmonary disease (COPD) is a common disabling disease characterized by progressive airflow obstruction. Great efforts were spent in the development of drugs able to improve symptoms, quality of life, reduce exacerbations ...

Characterization of the positive and negative inotropic effects of acetylcholine in the human myocardium [PDF]

, 1995
In the human isolated myocardium, acetylcholine (10−9 to 10−3 M) elicited a biphasic inotropic effect (a decrease in the lower and an increase in the higher concentration range) in atrial and a positive inotropic effect in ventricular trabeculae. However,

Structure-based discovery of selective positive allosteric modulators of antagonists for the M2 muscarinic acetylcholine receptor

Proceedings of the National Academy of Sciences of the United States of America, 2018
Significance The orthosteric binding sites of the five muscarinic acetylcholine receptor (mAChR) subtypes are highly conserved, making the development of selective antagonists challenging.

Combination therapy with indacaterol and glycopyrronium bromide in the management of COPD: an update on the evidence for efficacy and safety

Therapeutic Advances in Respiratory Disease, 2015
The international guidelines on chronic obstructive pulmonary disease (COPD) recommend inhaled bronchodilators for maintenance treatment of the disease. These drugs include β2-agonists and muscarinic antagonists, which are both available as short-acting ...

Muscarinic M1 receptors stimulated by intracerebroventricular administration of McN-A-343 reduces the nerve injury-induced mechanical hypersensitivity via GABAB receptors rather than GABAA receptors in mice

Journal of Pharmacological Sciences, 2020
Cholinergic neurons play an important role in the higher functions of the brain, such as the memory, cognition, and nociception. However, the exact mechanism behind how the stimulation of all the muscarinic M1 receptors in the entire brain results in the
