Abstract:
The endocannabinoid (EC) system is a physiological system with an important regulatory role in numerous biological functions, both centrally and peripherally. In certain conditions it can become hyperactive and induce a variety of disorders. The system has two receptor types, designated CB1 and CB2 (present respectively in the CNS and the periphery), as well as endogenous ligands (AEA and 2-AG) and equipment for transporting, synthesizing and degrading them. The discovery of specific CB1 antagonists has opened up interesting new possibilities for the treatment of obesity, diabetes and cardiometabolic risk factors.

Drug-Receptor Interaction: Agonist
Agonists can bind to receptors in different ways. Some agonists bind directly to the receptor's active site, mimicking the endogenous ligand's action.
Drug-Receptor Interactions
Several parameters, such as the drug's affinity for its receptor and its efficacy, which is its ability to activate the receptor, determine the drug's effect on the tissue.
G Protein-coupled Receptors
GPCRs are also called heptahelical, 7TM, or serpentine receptors, and consist of seven (H1-H7) transmembrane alpha-helices that span the bilayer to form a cylindrical core. The transmembrane helices are connected by three extracellular loops and three...
