Oxotremorine M is a muscarinic receptor agonist that activates both M2 and M3 subtypes of muscarinic receptors. It is a potent cholinergic agonist that stimulates the parasympathetic nervous system by mimicking the action of acetylcholine. Oxotremorine M binds to muscarinic receptors in various tissues, including smooth muscle, cardiac muscle, and exocrine glands, leading to a range of physiological responses. Oxotremorine M is used to study the role of muscarinic receptors in different biological processes. It modulates neurotransmitter release and synaptic transmission, providing insights into the mechanisms of neuronal communication. Oxotremorine M is for investigating the function of muscarinic receptors and their role in various physiological and pathological conditions.
