Chemical Structure

Biological activities

Rimonabant is an antagonist of the cannabinoid receptor type 1 (CB1). Rimonabant has a high affinity for the CB1 with an IC50 of 5 nM. Rimonabant is also shown to be potent in the CHO-hCB1R-Luciferase assay, with an IC50 of 92.5 nM.[1] Rimonabant has a high affinity for the CB1 with a Ki of 5.6 nM, and low affinity for the CB2 with a Ki > 1 mM. [2] Oral treatment of obese (fa/fa) rats with rimonabant (30 mg/kg) daily for 8 weeks abolishes hepatic steatosis. Rimonabant treatment reduces the high plasma level of the proinflammatory cytokine TNFa and increases the reduced plasma level of the anti-inflammatory hormone adiponectin. Rimonabant treatment also improves dyslipidemia by both decreasing plasma levels of triglycerides, free fatty acids, and total cholesterol and increasing the HDLc/LDLc ratio. [3] Rimonabant has anti-atherosclerotic effects in LDLR-/- mice. Rimonabant-treated animals have significantly reduced MCP-1, IL12p40/p70, and VCAM-1 levels. [4]

Protocols

Rimonabant is dissolved in Tween 80 (1%) and saline (99%).[5]
