Used as a selective positive allosteric modulator of the M4 muscarinic acetylcholine receptor, this compound is primarily employed in neuroscience research to study cholinergic signaling pathways. It shows potential in modulating dopamine release, making it a tool compound for investigating disorders such as schizophrenia, Parkinson’s disease, and substance use disorders. Its selectivity for the M4 receptor subtype allows researchers to probe the physiological and behavioral roles of this receptor without significant off-target effects. Preclinical studies use it to assess cognitive function, motor control, and psychiatric disease models.
