WAY-388788 is primarily used in neuroscience research as a potent and selective agonist for the 5-HT6 receptor. Its main application lies in studying cognitive functions, particularly in models related to learning and memory. Researchers utilize this compound to investigate the role of 5-HT6 receptor activation in neurodegenerative conditions such as Alzheimer's disease. It has shown pro-cognitive effects in preclinical studies, enhancing memory performance in animal models when administered at effective doses. Due to its ability to cross the blood-brain barrier efficiently, it is a valuable tool in central nervous system drug development. WAY-388788 is not used clinically but serves as a critical pharmacological agent in understanding serotonin receptor pathways and developing potential therapeutics for cognitive disorders.
