描述:

AM251 is a potent CB1 receptor antagonist (IC50 = 8 nM, Ki = 7.49 nM) that displays 306-fold selectivity over CB2 receptors; also potent GPR55 agonist (EC50 = 39 nM).

溶解性:Ethanol :13.9 mg/mL (25 mM)
DMSO :55.5 mg/mL (100 mM)

体外研究:

AM251 reduces veratridine-dependent (tetrodotoxin suppressible) release of L-glutamic acid and GABA from synaptosomes with IC50 of 8.5 μM and 9.2 μM, respectively. AM251 increases (by 2.3 times) the Kd of radioligand without altering Bmax. AM251 inhibits equilibrium binding by allosterically accelerating the dissociation of the -batrachotoxinin A 20-alpha-benzoate:sodium channel complex. AM251 reduces cholesteryl ester synthesis in unstimulated and acetylated LDL-stimulated Raw 264.7 macrophages, CB2+/+ and CB2 ?/? peritoneal macrophages.

体内研究:AM251 causes a sustained reduction of daily food intake in the rat. AM251 produces food avoidance and behaviors associated with nausea but does not impair feeding efficiency in rats. AM251 disrupts memory consolidation of the inhibitory avoidance task. AM251 has caused a significative decrease in the test step-down latency when compared to the control group, but no differences are detected in the open field habituation task, including the number of crossings, i.e. there are no motor effects. AM251 (4.0 mg/kg) reduces freezing during a conditioned tone cue played within a novel context.
