An analog of AEA that potentiates the activity of endogenous AEA by blocking its re-uptake into presynaptic neurons; selectively inhibits the carrier-mediated transport of AEA without affecting anandamide hydrolysis; inhibits the transport of AEA with an IC50 value of 1 µM in rat neurons and 5 µM in rat astrocytes; enhances and prolongs exogenous AEA-induced analgesia at a dose of 10 mg/kg in in vivo models.
