Chemical compound

4-DAMP (1,1-dimethyl-4-diphenylacetoxypiperidinium iodide) is aselectivemuscarinic acetylcholine receptor (mAChR) M3antagonist.[2] It is also able to antagonizeM1 receptors but has preferential activity at the M3 receptor.[3][4] It competitively binds to the acetylcholine binding site on mAChRs, causing right-ward shift in the dose response curves for mAChR agonists.
