CB1 antagonist 1 is a CB1 receptor antagonist, used in the research of obesity and metabolic syndrome, neuroinflammatory disorders, cognitive disorders, and gastrointestinal disorders, psychosis, and cardiovascular.
Leelamine hydrochloride, a tricyclic diterpene extracted from pine tree bark, inhibits the transcriptional activity of the androgen receptor, known to regulate fatty acid synthesis [2,3]. This compound acts as a cannabinoid receptor type 1 (CB1) agonist and suppresses SREBP1-regulated fatty acid/lipid synthesis in prostate cancer cells, irrespective of androgen receptor status.
In humans, two forms of diacylglycerol lipase, DAGLα and DAGLβ, generate the endocannabinoid 2-arachidonoyl glycerol by attacking DAG at the sn-1 position. O-7460 is a selective inhibitor of 2-AG biosynthesis via DAGLα (IC50 = 690 nM). It demonstrates much weaker inhibition towards human monoacylglycerol lipase and rat brain fatty acid amide hydrolase (IC50s > 10 μM) and does not bind to CB1 or CB2 cannabinoid receptors (Kis > 10 μM). At 0-12 mg/kg, i.p. in mice, O-7460 was reported to dose-dependently inhibit high-fat diet intake and reduce body weight.
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.
