Rimonabant, also known as SR141716, was the first selective CB1 (cannabinoid 1) central receptor inverse agonist (Ki = 1.8 nM). It is widely used as a tool to investigate CB receptor properties and the mechanisms by which CB agonists exert their pharmacological effects. In rodent models and clinical trials, rimonabant effectively induces lipolysis, reduces hepatomegaly, decreases body weight, and improves dyslipidemia by reducing triglyceride, free fatty acid, and total cholesterol levels and by increasing HDL/LDL ratios. However, rimonabant reportedly produces adverse psychiatric and neurological effects (e.g., depression or anxiety) and therefore is not approved by the FDA for use as a weight control medication. Rimonabant elicits antiproliferative and immunomodulatory effects (e.g., cell cycle arrest, increased expression of IκB and phosphorylated Akt, and decreased expression of NF-κB, phosphorylated ERK1/2, COX-2, and iNOS) in vitro.
