Carbamoylcholine, also known as carbachol, is an analog of acetylcholine that activates acetylcholine receptors (AChR). Carbamoylcholine is an agonist of both nicotinic (nAChR) and muscarinic (mAChR) receptors, with reported Ki values ranging from 10 to 10,000 nM for different receptors and different preparations. Carbamoylcholine (chloride) is used to study responses mediated by nAChR and mAChR, including smooth muscle contraction, gut motility, and neuronal signaling.
