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 ...

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 in rat uterus
European Journal of Pharmacology, 1994The aim of this study was to characterise the muscarinic receptor present in the uterus of the virgin rat. Homogenate binding studies were undertaken using [3H]quinuclidinyl benzilate as the radioligand and atropine (10 microM) to determine non-specific binding.

Antidepressants and the Muscarinic Acetylcholine Receptor
Archives of General Psychiatry, 1977Several tricyclic antidepressants have been assessed for their potency in binding to the muscarinic acetylcholine receptor of brain and intestine. Amitriptyline hydrochloride is about ten times as potent as imipramine hydrochloride. Dimethylated drugs are more potent than monomethylated ones.

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).

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
