FUB 359 is primarily utilized in research settings to study the endocannabinoid system and its receptors. It acts as a potent agonist for cannabinoid receptors, making it valuable for investigating the physiological and psychological effects of cannabinoid activation. Researchers use it to explore potential therapeutic applications, such as pain management, anxiety relief, and appetite regulation. Additionally, it aids in understanding the mechanisms underlying cannabinoid-related disorders and the development of targeted treatments. Its high potency and selectivity make it a useful tool for pharmacological studies, though it is not approved for medical or recreational use.
