WAY-330332 is primarily used in scientific research as a selective antagonist for the 5-HT6 receptor, making it a valuable tool compound in neuroscience and pharmacology studies. It has been investigated for its potential to modulate cognitive functions, particularly in models related to Alzheimer’s disease and other cognitive disorders. By blocking the 5-HT6 receptor, WAY-330332 helps researchers understand the role of serotonin signaling in learning, memory, and behavior. It has shown procognitive effects in preclinical models when administered alone or in combination with other agents. Due to its specificity, it is also used to validate the therapeutic potential of 5-HT6 receptor modulation without the confounding effects of activity at other receptor sites. Its application remains confined to laboratory and experimental settings, with no current clinical use in humans.
