Application

Rimonabant hydrochloride has been used as an antagonist of cannabinoid 1 (CB1) receptor:
  • to study its effects on protein synthesis in C2C12 myotubes
  • to analyze its effects on human astroglia
  • in combination with methanandamide (mAEA) to study its effects on murine gastric vagal afferent mechanosensitivity

Biochem/physiol Actions

Rimonabant acts as a mycobacterial membrane protein large 3 (MMPL3) inhibitor. Rimonabant hydrochloride exhibits therapeutic activity against weight reduction and smoking cessation.
Rimonabant hydrochloride (SR-141716A) is a potent and selective CB1 cannabinoid inverse agonist/antagonist with a Ki of 1.6 nM, minimal affinity for CB2, and and some GPR55 agonist activity. Rimonabant was developed as an anti-obesity drug because of its appetite suppressant activity, but was taken off the market because of side effects of depression and anxiety.
Rimonabant hydrochloride (SR-141716A) is a potent and selecvtive CB1 cannabinoid inverse agonist/antagonist with some GPR55 agonist activity and an appetite suppressant.

Here we demonstrate that repeated microinjections
