Muscarinic Receptor Antagonists
2016Parasympathetic activity is increased in patients with chronic obstructive pulmonary disease (COPD) and asthma and appears to be the major reversible component of airway obstruction. Therefore, treatment with muscarinic receptor antagonists is an effective bronchodilator therapy in COPD and also in asthmatic patients.

Abstract:The muscarinic cholinergic receptors in the urinary bladders of man, guinea pig, rat and rabbit were studied by means of a receptor binding technique, with L‐quinuclidinyl [phenyl4‐3H]benzilate, (‐)3H‐QNB, as radioligand. The potential role of the receptors in the supersensitivity of the rat bladder to muscarinic agonists, following ...

Structure and Regulation of Muscarinic Receptors
Annual Review of Physiology, 1989Our knowledge of muscarinic receptor structure, mechanism, and regulation has increased enormously over the past five years. At this time, expression of receptor subtype and coupling via signal transducing elements to specific effector systems seems to be cell or tissue specific events.

Endocytosis and recycling of muscarinic receptors
Life Sciences, 1999Agonist stimulation causes the endocytosis of many G protein-coupled receptors, including muscarinic acetylcholine receptors. In this study we have investigated the agonist-triggered trafficking of the M3 muscarinic receptor expressed in SH-SY5Y human neuroblastoma cells.

Muscarinic receptors exist in both peripheral tissues and the central nervous system. Their activation is responsible for all the effects elicited by parasympathetic stimulation in the peripheral organs and modulate ganglionic transmission (Wallis, 1979).

Interaction of Atropine with the Muscarinic Receptor
Nature, 1970WE report here the crystal structures of two muscarinic antagonists of acetylcholine, (−)-(S)-hyoscine hydrobromide1 and (−)-(S)-hyoscyamine hydrobromide (atropine). Correlation of these two structures and that of quinuclidinyl benzilate hydrobromide2 shows marked similarities among the three molecules although they are subjected to very different ...

Abstract The pharmacology of acetylcholine is in many ways a very old subject. The use of antimuscarinic plant extracts as both poisons and therapies can be traced back to ancient times. Thus, Linnaeus gave the systematic name Atropa belladonna to the deadly nightshade, in homage to Atropos of Greek mythology, who cuts the thread of life,

CNS muscarinic receptors and muscarinic receptor agonists in Alzheimer disease treatment
This review explores the main aspects that form the basis of the cholinergic-oriented treatment of Alzheimer disease. Muscarinic acetylcholine receptor subtypes in the brain and periphery are discussed. It includes a new and updated overview of the involvement of muscarinic receptors in Alzheimer disease and the recent development of new and highly ...Abraham, Fisher, Allan I, Levey
