4-DAMP (1,1-dimethyl-4-diphenylacetoxypiperidinium iodide) is a selective muscarinic acetylcholine receptor (mAChR) M3 antagonist. [2] It is also able to antagonize M1 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.
