[Selective muscarinic receptor antagonists].
3ubtypes of muscarmic receptors, first hypothesized by Birdsall et al. ~ to explain the anomalous binding of cholinergic agonists to brain receptors~ were later demonstrated with the seEective muscarinic antagonist, pirenzepine 2. Interestingly, the search for selective antagonists, which usually follows the acceptance of a concept, antedated by many years the notion of heterogeneity of rmecari...
متن کاملVolatile anaesthetics have differential effects on recombinant m1 and m3 muscarinic acetylcholine receptor function.
Muscarinic acetylcholine signalling plays major roles in regulation of consciousness, cognitive functioning, pain perception and circulatory homeostasis. Halothane has been shown to inhibit m1 muscarinic signalling. However, no comparative data are available for desflurane, sevoflurane or isoflurane, nor have the anaesthetic effects on the m3 subtype (which is also prominent in the brain) been ...
متن کاملBinding and functional profiles of the selective M1 muscarinic receptor antagonists trihexyphenidyl and dicyclomine.
The selectivity profiles of the muscarinic receptor antagonists dicyclomine and trihexyphenidyl have been examined in binding and functional studies and compared with those of pirenzepine and atropine. Dicyclomine, trihexyphenidyl and pirenzepine demonstrated the highest affinity for the M1 muscarinic receptor subtype as revealed in competition experiments against [3H]-pirenzepine labelling of ...
متن کاملOrthosteric and allosteric modes of interaction of novel selective agonists of the M1 muscarinic acetylcholine receptor.
Recent years have witnessed the discovery of novel selective agonists of the M(1) muscarinic acetylcholine (ACh) receptor (mAChR). One mechanism invoked to account for the selectivity of such agents is that they interact with allosteric sites. We investigated the molecular pharmacology of two such agonists, 1-[3-(4-butyl-1-piperidinyl)propyl]-3,4-dihydro-2(1H)-quinolinone (77-LH-28-1) and 4-n-b...
متن کاملMuscarinic acetylcholine receptor M1 and M3 subtypes mediate acetylcholine-induced endothelium-independent vasodilatation in rat mesenteric arteries.
The present study investigated pharmacological characterizations of muscarinic acetylcholine receptor (AChR) subtypes involving ACh-induced endothelium-independent vasodilatation in rat mesenteric arteries. Changes in perfusion pressure to periarterial nerve stimulation and ACh were measured before and after the perfusion of Krebs solution containing muscarinic receptor antagonists. Distributio...
