LY 344864 racemate is primarily utilized in research settings to study its effects on serotonin receptors, particularly the 5-HT1F subtype. It is often employed in pharmacological studies to understand the role of these receptors in various physiological and neurological processes. Researchers use it to explore potential therapeutic applications, such as in the treatment of migraines, due to its ability to modulate serotonin pathways. Additionally, it serves as a valuable tool in preclinical studies to investigate receptor binding, signal transduction, and the development of new drugs targeting serotonin-related disorders. Its application is largely confined to experimental and investigative contexts, contributing to advancements in neuroscience and drug discovery.
