AM521 is a potent cannabinoid 1 (CB1) receptor antagonist with IC50 of 8 nM and Ki of 7.49 nM.
The cannabinoid receptor (CB1 and CB2) is a member of G-protein coupled receptor which plays a significant role in physiologic processes such as cognitive and immune functions.
AM251 inhibited the coupling of cannabinoid 1 receptor agonists and antagonists onto the rat brain membranes [1]. In hippocampus, 2 μm AM 251 reduced the endocannabinoids inhibitory effects on GABA release [2]. 1 μm AM 251 inhibited endocannabinoid-signaled depression of interneuron firing [3]. AM251 reduced neuronal excitability and inhibited excitatory and inhibitory transmitter release via inhibition of voltage-dependent Na+ channels [4].
AM251 caused sustained anorectic effect in rat for obesity treatment [5]. AM251 may also disrupt the training – induced increase of hippocampus cannabinoids level that promotes memory consolidation [6].
