Used in pharmaceutical research as a potent and selective antagonist of the GPR139 receptor, which is implicated in neurological and psychiatric disorders. Shows potential in the development of treatments for conditions such as schizophrenia, depression, and Parkinson’s disease due to its ability to modulate dopaminergic and serotonergic pathways. Its carboxylic acid group allows for salt formation, improving solubility and bioavailability in preclinical studies. Also employed as a biochemical tool to investigate GPR139 receptor function in cellular and animal models.
