The M2 muscarinic acetylcholine receptor (mAChR) possesses at least one binding site for allosteric modulators that is dependent on the residues (172)EDGE(175), Tyr(177), and Thr(423). However, the contribution of these residues to actions of allosteric agonists, as opposed to modulators

At the rat motor endplate, pre-synaptic facilitatory adenosine A2A and muscarinic M1 receptors are mutually exclusive. We investigated whether these receptors share a common intracellular signalling pathway. Suppression of McN-A-343-induced M1 facilitation of [3H]ACh release was partially recovered when CGS21680C

Investigating how a test drug alters the reaction of a site-directed electrophile with a receptor is a powerful method for determining whether the drug acts competitively or allosterically, provided that the binding site of the electrophile is known. In this

We explored the interaction of a nitrogen mustard derivative of acetylcholine with the human M(2) muscarinic receptor expressed in Chinese hamster ovary cells using the muscarinic radioligand, [3H]N-methylscopolamine (NMS). Acetylcholine mustard caused a concentration-dependent, first-order loss of [3H]NMS binding at

The unusual pharmacology of McN-A-343 was first described by Roszowski in 1961. The agonist appeared to be a selective stimulant of muscarinic receptors in sympathetic ganglia, now known to be the muscarinic M₁ receptor subtype. However, subsequent research demonstrated that
