Used as a selective positive allosteric modulator of the M4 muscarinic acetylcholine receptor, this compound is primarily employed in neuroscience research to study receptor function and signaling pathways. It has shown potential in preclinical studies for treating central nervous system disorders, particularly those involving dopaminergic hyperactivity, such as schizophrenia and substance use disorders. Its ability to modulate M4 receptors without directly activating them allows for more precise control of cholinergic transmission, reducing side effects commonly seen with orthosteric agonists. It is also utilized in pharmacological studies to explore cognitive function, motor control, and neuroprotection.
