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

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)

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

Our previous data indicate that M3 muscarinic receptors mediate carbachol induced bladder contractions. The data presented here were obtained by selective alkylation of M3 receptors with 4-DAMP mustard and suggest that the M2 receptor subtype may be involved in inhibition

Possible hypertension-related alterations in the nature- and receptor reserve of the muscarinic (M) receptors mediating endothelium-dependent vasodilation remain to be elucidated. Therefore we used 4-diphenylacetoxy-N-(2-chloroethyl)-piperidine (4-DAMPmustard), an irreversible M3-receptor antagonist, to estimate the receptor reserve for the methacholine (MCh)-induced endothelium-dependent
