Allosteric antagonists of the muscarinic acetylcholine receptor
Biochemical Pharmacology, 1991For the most part, the interaction of these selective antagonists with muscarinic receptors has been interpreted in the context of simple competitive bimolecular reaction which obeys the law of mass action. In fact, the use of selective antagonists as a pharmacological tool to identify receptor types and subtypes is based on this premise.

Aprophit: An irreversible antagonist for muscarinic receptors
Biochemical Pharmacology, 1990The development of selective irreversible ligands has proven to be an invaluable technique for the isolation, purification and characterization of many receptor proteins. An isothiocyanato-derivative of the muscarinic antagonist aprophen was synthesized and evaluated as a potential irreversible ligand for muscarinic receptors.

The effects of atropine, pirenzepine and AF-DX 116 on the high K(+)-evoked release of endogenous ACh from rat hippocampal slices were compared. As expected, atropine in concentrations of 10(?5) and 10(?6)M increased the release of acetylcholine, to 128 and 157% of the control value, respectively. While AF-DX 116 was also able to increase the release to

[Antianaphylactic effects of muscarinic antagonists].
Eksperimental'naia i klinicheskaia farmakologiia, 2010The study was carried out on color guinea pigs, in which anaphylactic shock was induced by sensitizing and challenging doses of normal horse serum (HS). Administration of atropine, ipratropium, or ipratropium in combination with neostigmine led to reduction of sensitizing effect of HS: anaphylactic index was decreased up to (2.2 - 2.4) +/- 0.1 ...

Benzylidene ketal derivatives as M2 muscarinic receptor antagonists
Bioorganic & Medicinal Chemistry Letters, 2000Benzylidene ketal derivatives were investigated as selective M2 receptor antagonists for the treatment of Alzheimer's disease. Compound 10 was discovered to have subnanomolar M2 receptor affinity and 100-fold selectivity against other muscarinic receptors. Also, 10 demonstrated in vivo efficacy in rodent models of muscarinic activity and cognition.

Selective muscarinic antagonists as bronchodilators.
Agents and actions. Supplements, 1992The non-selective muscarinic antagonist ipratropium is widely used as bronchodilator. Due to its pharmacokinetic properties this drug, after inhalation, acts only locally on the airways and no unwanted anticholinergic side-effects are observed. Another approach is the use of selective muscarinic antagonists. Based on their selectivity for M3- and/or M1-

Improved Muscarinic Antagonists as Anticholinesterase Antidotes
1990Abstract : Muscarinic antagonists play an important role in anticholinesterase agent therapy by reducing the response of muscarinic receptors to acetylcholine, acting synergistically with cholinesterase reactivators. Therapy with antagonists such as atropine is difficult to manage because of the toxicity of these compounds, atropine antagonizes the ...
