BMY 7378 dihydrochloride is primarily utilized in research settings as a selective antagonist for the 5-HT1A receptor. It is commonly employed in pharmacological studies to investigate the role of serotonin receptors in the central nervous system. This compound helps researchers understand the mechanisms underlying various neurological and psychiatric conditions, such as anxiety, depression, and schizophrenia. Additionally, BMY 7378 dihydrochloride is used in experimental models to study the effects of serotonin receptor modulation on behavior, cognition, and neurochemical pathways. Its specificity for the 5-HT1A receptor makes it a valuable tool for dissecting serotonin-related signaling and developing potential therapeutic agents targeting this receptor.
