WAY-310331 is primarily used in scientific research as a selective agonist for the GPR139 receptor, a G-protein-coupled receptor expressed in the central nervous system. Its main application lies in neuropharmacological studies, where it helps investigate the role of GPR139 in regulating neurotransmitter systems, particularly those involving dopamine and glutamate. Researchers use WAY-310331 to explore potential pathways related to psychiatric and neurological disorders such as schizophrenia, depression, and addiction. Due to its selectivity and potency, it serves as a valuable tool compound for validating GPR139 as a therapeutic target. It is not used clinically and remains restricted to preclinical research settings.
