WAY-298592 is primarily used in scientific research to study serotonin receptor activity, particularly targeting the 5-HT6 receptor subtype. It serves as a selective antagonist, helping researchers investigate the role of 5-HT6 receptors in cognitive function, memory, and neurodegenerative conditions such as Alzheimer's disease. Due to its high selectivity, it is valuable in pharmacological studies aiming to understand the effects of serotonin modulation on behavior and brain function. It is not used in clinical medicine and is intended solely for laboratory and experimental purposes.
