Biological Activity

FAAH-like anandamide transporter (FLAT) inhibitor (IC50 = 1.8 μM); cytosolic variant of FAAH-1 that binds anandamide. Attenuates anandamide internalization and deactivation in vitro and in vivo respectively. Exhibits analgesic effects in rodent models of CB1-mediated nociceptive and inflammatory pain.
