Rimonabant

SKU: orb1308349

Description

Rimonabant (SR141716) is a selective CB1 receptor inverse agonist developed as an anti-obesity anorectic agent. It is widely used in metabolic and neurological research, with applications in both in vitro binding assays and in vivo models of appetite regulation and energy homeostasis.

In Vivo
Rimonabant is administered intraperitoneally or orally potently and dose-dependently antagonize classical pharmacological and behavioural effectos of cannabinoid receptor agonists. In the mouse model of azoxymethane-induced colon carcinogenesis, Rimonabant significantly decreased aberrant crypt foci (ACF) formation, which precedes colorectal cancer. Rimonabant (10 mg/kg by gavage) is fed for 2 weeks to 3-month-old male obese Zucker rats as an impaired glucose tolerance model and for 10 weeks to 6-month-old male obese Zucker rats as a model of the metabolic syndrome. RANTES (Regulated upon Activation, Normal T cell Expressed, and Secreted) and MCP-1 (monocyte chemotactic protein-1) serum levels are increased in obese vs lean Zucker rats and significantly reduced by long-term treatment with Rimonabant, which slowes weight gain in rats with the metabolic syndrome. Neutrophils and monocytes are significantly increased in young and old obese vs lean Zucker rats and lowered by Rimonabant. Platelet-bound fibrinogen is significantly enhanced in obese vs lean Zucker rats of both age, and is reduced by Rimonabant. Platelets from obese rats are more sensitive to thrombin-induced aggregation and adhesion to fibrinogen, which are both attenuated by Rimonabant therapy.

In Vitro
Rimonabant dose-dependently reduces ACAT activity in Raw264.7macrophages with IC50 of 2.9 μM and isolated peritoneal macrophages. Rimonabant inhibits ACATactivity in intact CHO-ACAT1 and CHO-ACAT2 cells and in cell-free assays with approximately equal efficiency with IC50 of 1.5 μM and 2.2 μM for CHO-ACAT1 and CHO-ACAT2, respectively. Consistent with ACAT inhibition, Rimonabant treatment blocks ACAT dependent processes in macrophages, oxysterol-induced apoptosis and acetylated-LDL induced foam cell formation. Rimonabant antagonizes the inhibitory effects of cannabinoid receptor agonists on both mouse vas deferens contractions and adenylyl cyclase activity in rat brain membranes in a concentration-dependent manner. Rimonabant significantly reduces cell growth and induces cell death of human colorectal cancer cells (DLD-1, CaCo-2 and SW620). Rimonabant is able to alter cell cycle distribution in all the cell lines tested. Particularly, Rimonabant produces a G2/M cell cycle arrest in DLD-1 cells without inducing apoptosis or necrosis.

Cell Research
Raw 264.7 cells (2 × 106 /well) in 12-well plates are rinsed with PBS and refed culture media supplemented with varying amounts of Rimonabant 1 hour prior to supplementation with 7-ketocholesterol (7KC). All wells are adjusted to receive equal amounts of vehicle. Following 16-hour incubation, caspase-3 and caspase 3-like activity are determined using a fluorogenic substrate (Ac-DEVD-AFC) and a spectrofluorometer equipped with a microplate reader.
