AM 404 is a selective inhibitor of anandamide transport [1]. Also, it is an agonist of CB1 cannabinoid receptor and potential vanilloid type 1 (TRPV1).

The endocannabinoid transporter (eCBT) is a transporter for the endocannabinoid. The blockade of anandamide transport has anti-nociceptive effects.

AM 404 is a selective anandamide transport inhibitor. AM404 inhibited anandamide transport with IC50 values of 1 and 5 μM in neurons and astrocytes, respectively. However, AM404 had no effect on FAAH activity or on uptake of arachidonate or ethanolamine. Also, AM404 exhibited affinity for CB1 receptors with Ki value of 1.8 μM [1]. In rat hepatic artery contracted with phenylephrine, AM404 evoked relaxations in a concentration-dependent way, which was inhibited by capsazepine, a vanilloid receptor antagonist. These results suggested that AM404 activated vanilloid receptors [2]. In SK-N-SH neuroblastoma cells, AM404 inhibited NFAT and NF-κB signaling pathways [3].

In mice, AM404 (10 mg/kg) significantly prolonged and enhanced anandamide-induced analgesia [1]. In rats, AM404 inhibited motor behaviors induced by quinpirole, a D2 family receptor agonist. In juvenile spontaneously hypertensive rats, AM404 inhibited hyperactivity [4].
