Used in research settings to modulate muscarinic acetylcholine receptors, particularly as a positive allosteric modulator selective for the M4 receptor subtype. This compound helps investigate the role of M4 receptors in neurological pathways, making it valuable in studies related to schizophrenia, addiction, and Parkinson’s disease. Due to its selectivity, it allows targeted exploration of receptor function without directly activating other muscarinic subtypes, supporting the development of more precise neuropharmacological treatments.
