A functional role for the M2 muscarinic receptor in smooth muscle contraction was investigated in isolated guinea pig ileum. Contractile responses to the muscarinic agonist oxotremorine-M (oxo-M) were measured in isolated ilea that had been pretreated with histamine (0.32 microM)

Irreversible ligands are useful tools for investigating the function of receptor subtypes in various physiological processes. The mechanism for alkylation involves the formation of a reversible receptor complex followed by a covalent reaction. The extent of receptor alkylation is determined

The compound 4-DAMP mustard (N-2-chloroethyl-4-piperidinyl diphenylacetate) is a 2-chloroethylamine derivative of the selective muscarinic antagonist 4-DAMP (N,N-dimethyl-4-piperidinyl diphenylacetate). At neutral pH, 4-DAMP mustard cyclizes spontaneously into an oziridinium ion that binds covalently with muscarinic receptors. Analysis of the kinetics of

Many irreversible antagonists have been shown to inactivate G protein-coupled receptors (GPCRs) and used to study agonists and spare receptors. Presumably, they bind to primary (agonist) binding sites on the GPCR, although noncompetitive mechanisms of antagonism have been demonstrated but

1. The role of muscarinic M2 and M3 receptors in ileal smooth muscle has been evaluated by use of selective receptor alkylation. The alkylating agents, 4-diphenylacetoxy-N-(2-chloroethyl)-piperidine (4-DAMP mustard) was studied for effects against (+)-cis-dioxolane, at muscarinic M2 and M3 receptors
