ABD459 is a neutral antagonist of the central cannabinoid 1 (CB1) receptor (Ki = 8.6 nM). It inhibits food consumption in nonfasted mice without affecting motor activity. ABD459 reduces active food seeking for 5-6 hours after treatment, with no rebound after washout. ABD459 also diminishes rapid eye movement (REM) sleep, with no alterations of wakefulness or non-REM sleep. | [Uses]
ABD459 is a CB1 receptor antagonist with significant effects on regulating food intake and sleep-wake cycles. ABD459 completely displaces CB1 agonist CP99540 (Ki = 8.6 nM) and antagonizes CP55940-induced GTPγS binding (KB = 7.7 nM). ABD459 may specifically modulate endogenous cannabinoid release through cholinergic activity and plays a role in attention and arousal regulation. ABD459 is suitable for research in neurological disorders[1]. | [storage]
