Overview

AM281 is a selective CB1 receptor antagonist with an IC50 of 9.91 nM. AM281 inhibits CB2 receptor with an IC50 of 13000 nM。 

Application:

AM281 has been used as a cannabinoid 1 receptor antagonist:
to study its effects on memory deficit following naloxone-precipitated morphine withdrawal in mice
to study the role of CB1 receptor system in modulating acetaldehyde-induced effects in rats during the extinction-, relapse-, and conflict-experiments
to study its effect on scopolamine-induced memory deficit using object recognition paradigm
to block synthetic cannabinoid (HU210)-induced analgesia in the ventrolateral orbital cortex (VLO) to evaluate the effect of CB1 receptors on the VLO modulation of pain

Biochemical and Physiological Mechanisms
AM281 is less lipophilic compared to its analog SR 141716A, a cannabinoid receptor antagonist. AM281 may prevent memory deficit post morphine withdrawal by inhibiting cannabinoid receptors in mice. Potent and selective CB1 cannabinoid receptor antagonist/
